The coffee cup suffused Captain Karen Blaylock's hands with a cheery warmth as she strode purposefully onto the bridge of her ship, the Excelsior-class starship Slayton. Though the alpha watch wasn't due to begin for another ten minutes, she wasn't at all surprised to see several key bridge officers already hard at work at their consoles, which hummed and beeped agreeably.

Commander Ernst Roget, her executive officer, turned toward her in the command chair and favored her with a reserved smile. "Captain on the bridge," he said, vacating the seat for her.

Heads turned toward Blaylock, distracted momentarily from their vigilance. These were good officers, science and engineering specialists all, and she hated allowing command protocol to interfere with their work, even momentarily. She often envied them their single-minded dedication to discovery. How ironic, she thought, to have allowed her command responsibilities to come between her and the very thing that had brought her out to the galactic hinterlands in the first place: the pursuit of pure knowledge.

Blaylock nodded a silent as you were, and each crewmember quickly returned to the work at hand. She took her seat and sipped her coffee.

Commander Cortin Zweller approached Blaylock from the science station on the bridge's starboard side. His thick shock of white hair was belied by the boyish twinkle in his eye. During the nearly four months he had served as chief science officer, he had proven to be a valuable member of the Slayton team. Though by no means a brilliant researcher, Zweller was well-liked by the other science specialists, an administrator apparently gifted with the good sense not to step on the toes of his better-trained subordinates -- unless absolutely necessary.

"The anomaly still seems to be hiding from us," Zweller said. "So far, at least."

Blaylock sighed, disappointed. The Slayton had last made long-range sensor contact with the subspace anomaly eight days previously, but had turned up nothing since. Several weeks before that, the Federation's Argus Array subspace observatory had detected intermittent but extremely powerful waves of subspace distortion that seemed to be coming from the region of space for which the Slayton was now headed. Unfortunately, the phenomenon had neither lasted long enough -- nor repeated itself regularly enough -- to reveal much else.

How wonderful it would have been, Blaylock reflected, to have discovered an entirely new physical phenomenon while en route to a dreary diplomatic appointment on gods-forsaken Chiaros IV. But Blaylock knew it would be just her luck for the anomaly to return briefly -- and then vanish forever -- while she and her crew were preoccupied with the tedium of galactic politics.

The captain turned toward Lieutenant Glebuk, the Antedean helmsman. In the year since Glebuk had come aboard, Blaylock had assiduously avoided asking the galley replicators to create sushi, one of her favorite foods. Glebuk, who was essentially a two-meter-tall humanoid fish, was notably edgy about such things.

Like most of her kind, Glebuk would have found the rigors of interstellar travel intolerable but for the effects of the cortical stimulator she wore on her neck. Its constant output of vertigo-nullifying neural impulses kept her from lapsing into a self-protective catatonic state during long space voyages. Despite this handicap -- or perhaps because of it -- Glebuk was one of the best helm officers Blaylock had ever worked with.

"What's our present ETA at the Chiaros system?" Blaylock asked Glebuk.

The helmsman fixed an unblinking, monocular gaze on the captain and whispered into the tiny universal translator mounted in the collar of her hydration suit. "The Slayton will reach the precise center of the Gulf in approximately fifty-three minutes. We will arrive at the fringes of the Chiaros system some six minutes later."

Blaylock nodded. Almost the precise center of the Geminus Gulf, she thought with a tinge of awe. Three wide, nearly empty sectors. Sixty light-years across, all together. Nearly two weeks travel time at maximum warp. Even after a decade of starship command, she found it hard to wrap her mind around such enormous distances.

During the long voyage into the Gulf, Blaylock had had plenty of time to familiarize herself with the region. More than enough time, actually, since so little was actually known about it, other than its size, location, and strategic significance -- or rather its lack thereof. It was well-known, however, that most of its sparse stellar population were not of the spectral types associated with habitable worlds. In the Geminus Gulf, young supergiant "O" type stars predominated -- the sort of suns whose huge mass blows them apart only a few hundred million years into their lifespans -- rather than the cooler, more stable variety, such as the "G" type star that sired Earth and its immediate planetary neighbors.

But the Geminus Gulf was important in at least one respect; it lay just outside the boundaries of both the Federation and the Romulan Star Empire, and it had yet to come formally into the sphere of influence of either power. Nearly smack in the center of the Gulf's unexplored vastness lay one inhabited world, the fourth planet of the politically nonaligned Chiaros system. Under recently negotiated agreements, neither the Federation nor the Romulans could establish a permanent presence in the Gulf until invited to do so by a spacefaring civilization native to the Gulf. Blaylock was only too aware that her job was to do everything the Prime Directive would allow to obtain that invitation from the Chiarosans, who comprised the only warp-capable culture yet known in the Gulf, and thus were the key to the entire region, and to whatever awaited discovery within its confines.

Never mind that there isn't any there there, Blaylock thought, absurdly reminded of the 20th-century human writer Gertrude Stein's often-mischaracterized description of an empty region on Earth.

Settling back into her chair, Blaylock smiled to herself. She had already reviewed the Chiarosan government's preliminary application for Federation membership. Less than two weeks from now, the planet's general population would formally vote on whether to invite in the Romulans or the Federation. Fortunately, since the pro-Federation position was being staunchly backed by the planet's extremely popular ruling regime, it seemed to Blaylock that her mission was already all but accomplished.

Blaylock therefore felt amply justified in allowing her thoughts to return to the matter of the mysterious subspace distortions -- and their possible causes. Now that they had piqued her curiosity, she couldn't bear the thought of leaving the bridge for a diplomatic conference whose results were already foreordained.

"Just how important is the captain's presence at this conference?" Blaylock said, turning toward Roget.

Seated in the chair beside Blaylock's, Roget leaned forward, his mahogany-colored brow wrinkled in evident confusion. "It's crucial, Captain. The natives of Chiaros IV are a warrior people. If you're not there, they're likely to take offense."

Her exec's discomfiture brought a small smile to her lips. "Don't panic, Ernie. I'm not planning on going AWOL. What I mean is, how important is it that the captain be present with the first away team?"

Roget appeared to relax at that. Stroking his jaw, he said, "It's not critical, I suppose. You have to remember, though, that the Chiarosans are very hierarchical and protocol-conscious."

"So I noticed," Blaylock said. "They've planned just about every minute of our itinerary while we're on their planet. And we won't even meet First Protector Ruardh until our third day on the planet. It's all just lower-level functionaries until then."

"'When in Rome,' Captain," Roget said.

"I agree. Therefore I've decided I'm staying aboard the Slayton until you finish up the preliminary business with the first away team. That'll give me at least another full day here on the bridge before I have to join you down on the planet."

Roget smiled knowingly. "You want to keep looking for those subspace distortions yourself."

Blaylock didn't smile back. Roget needed to know that she was deadly serious. "There's more at stake here than my scientific curiosity. We already know that the Romulans will have a delegation on Chiaros."

"That's unavoidable, unfortunately, under the treaties." Roget, too, was no longer smiling.

"Wherever you find Romulan diplomats, you'll probably also find a cloaked Romulan ship nearby -- certainly up to no good."

Roget regarded her with a silent scowl. He was giving her the look again. She knew that he had to be thinking, a cloaked Romulan ship that causes intermittent subspace distortions that can be picked up five sectors away? Fortunately, Roget was not one to question her orders in front of the crew.

Until I find out the answer, she told herself, I'll be damned if I'm off this ship one second longer than I absolutely have to be.

At that moment, Zweller rose from his station and faced Blaylock, an eager expression on his face. Though he was in his sixties, his unbridled enthusiasm made him appear much younger.

"Captain?"

"Yes, Mr. Zweller?"

"If it's all right with you and Commander Roget, I'd like to be part of the first away team. From what I've read about Chiaros IV, the place could keep a dozen science officers busy for years."

Blaylock looked toward her exec, who nodded his approval. She turned the matter over in her mind for a moment, then rose from her chair and regarded Zweller approvingly. She liked officers who weren't afraid to show a little initiative.

"All right, Mr. Zweller. Assemble a few of the department heads in the shuttlebay at 0800 tomorrow. You and Commander Roget will oversee the opening diplomatic ceremonies."

Zweller thanked Blaylock, then returned to his station to contact his key subordinates. She had no doubt that Chiaros IV would more than justify his scientific curiosity. For a moment, she regretted her decision not to lead the first away team.

But she had a mystery to solve, and a ship to worry about. Needs must, Blaylock thought, when the devil drives.

Or the Romulans.

Sitting beside Roget in the cockpit of the shuttlecraft Archimedes, Zweller finished his portion of the preflight systems checks in less than five minutes. The eight-person craft was ready for takeoff even as the heads of the biomedical science, planetary studies, xenoanthropology, and engineering departments took their seats.

At Roget's command, the triple-layered duranium hangar doors opened, accentuating the faint blue glow of the shuttlebay's atmospheric forcefield. The shuttle rose on its antigravs, moved gently forward, and accelerated into the frigid vastness of space.

The perpetually sunward side of Chiaros IV suddenly loomed above the Archimedes, presenting a dazzling vista of ochers and browns. Gray, vaguely menacing clouds surged over the equatorial mountain ranges. High above the terminator separating eternal night from unending day, Zweller could see the glint of sunlight on metal -- Chiaros IV's off-planet communications relay, tethered to the planet's narrow habitable zone by a network of impossibly slender-looking cables. Zweller noticed that the portion of the tether that plunged into the roiling atmosphere was surrounded by transitory flashes of light.

Lightning? he wondered, then looked more closely. No, it's thruster fire. If the Chiarosans didn't compensate somehow for the motions of their turbulent atmo-sphere, that orbital tether wouldn't last ten minutes.

Zweller took in this vista -- the untamable planet as well as the tenacious efforts of the Chiarosans to subdue it -- with unfeigned delight.

"Hail the Chiarosans, Mr. Zweller," Roget said, interrupting his reverie. Zweller complied, immediately all business once again. His hail was answered by a voice as deep as a canyon, which cleared the shuttlecraft to begin its descent into the churning atmosphere. The computer received the landing coordinates and projected a neat, elliptical course onto the central navigational display.

"A pity we can't just beam straight down to the capital," Roget said as the Slayton receded into the distance.

Andreas Hearn, the Slayton's chief engineer, spoke up from directly behind Zweller. "Between the radiation output of the Chiarosan sun, the planet's intense magnetosphere, and the clash of hot and cold air masses down there, we can't even get a subspace signal down to the surfaceleast not without the orbital tether relay. I wouldn't recommend trying to transport anyone directly through all that atmospheric hash."

"Oh, enough technical talk," said Gomp, the Tellarite chief medical officer, who was seated in the cabin's aftmost section. "I want to know what these people are really like. The only things I've seen so far are their official reports to the Federation. Medically speaking, all I can really say about them is that they're supposed to be triple-jointed and faster than Regulan eel-birds."

"Then I wouldn't recommend challenging them on the hoverball court," Hearn said with a chuckle.

The Archimedes entered the upper atmosphere. On the cockpit viewer, Zweller watched as an aurora reached across the planet's south pole with multicolored, phosphorescent fingers. Lightning split the clouds in the higher latitudes. Atmospheric friction increased, and an ionized plasma envelope began forming around the shuttle's hull.

"Gomp makes a good point," said xenoanthropologist Liz Kurlan, as though this didn't happen very often. "All we know about these people so far is what they want us to know."

"So we'll start filling in those gaps in our knowledge today," Roget said with a good-natured shrug. "That's why we're all here, isn't it?"

Sitting in silence, he moved his fingers with deliberate precision over the controls. Then the shuttle hastened its descent toward the rapidly approaching terminator, the demarcation line between the planet's endless frigid night and its ever-agitated, superheated sunward side.

On the Slayton's bridge, Blaylock heard an uncharacteristic urgency enter Glebuk's voice. "Captain! The anomaly has reappeared!"

The bridge crew suddenly began moving in double-time. Blaylock was on her feet in an instant. "Location!"

"Scanning," Glebuk said.

Ensign Burdick, the young man at the forward science station, beat the Antedean to the answer. "A massive subspace distortion wave-front has appeared... four-point-eight astronomical units south of the planet's orbital plane."

"Speed?"

"One-tenth light-speed in all directions. Speed is constant."

"Transfer the coordinates to the helm," Blaylock said.

"Coordinates received," acknowledged Glebuk.

"That's our heading, helmsman. Engage at warp factor two. Take us half an AU from the wave-front, then full stop. Close, but not too close. On my mark, get the hell away at maximum warp."

"Aye," Glebuk said, altering the ship's speed and direction. Blaylock could feel the slight telltale vibration in the deckplates.

"Ensign Burdick, record everything you can about those subspace distortions," Blaylock barked, then whirled toward the tall, dark-tressed woman who was working the aft communications station. "Lieutenant Harding, try to raise the Archimedes."

Precisely sixteen seconds later, the Slayton had come to a full stop at a safe distance from the slowly-expanding subspace effect. On the forward viewer, the starfield rippled slightly, as though attached to a curtain being blown by a strong wind.

"No contact with the Archimedes, Captain," Harding said. "They must have already entered Chiaros IV's atmosphere."

"Captain!" Burdick suddenly cried out from the science station, getting Blaylock's full attention. "The wave-front's speed has just increased almost a hundredfold!"

How can that be? Blaylock thought in the space of a heartbeat. Unless the phenomenon has begun dropping in and out of normal space, gaining velocity from subspace...

She wasted no time. "Raise shields!" she shouted. "Glebuk, get us out of--"

The wave-front struck at that moment, instantly overwhelming the Slayton's inertial dampers. The bridge went dark and the deck lurched sideways, throwing Blaylock from her feet. Her body slammed hard into a railing, which she grabbed with both arms. She felt at least one of her ribs give way under the impact. A portside panel exploded in a bright shower of sparks, leaving tracers of light behind her eyelids. She heard a sharp scream cut through the alarm klaxons, then cease.

The emergency lighting kicked in, casting an eerie, blood-colored pall across the bridge. The deck leveled itself. Smoke billowed from a burning panel. Bodies lay sprawled everywhere, some moving, some not. The bridge viewer was dead. Blaylock noticed that Glebuk had been hurled forward over the helm console and onto the deck. The Antedean lay still, water seeping from a tear in her hydration suit, her neck bent into an impossible question-mark shape. Fighting down a surge of horror, Blaylock sat behind the helm console.

The controls resolutely refused to respond. What the hell was she dealing with here?

Blaylock spun her chair toward Burdick, whom Harding was helping back into his seat. Blood surged into the ensign's eyes from a gash on his forehead.

"Status report!" Blaylock snapped.

Harding, the more experienced officer, began consulting a nearby undamaged instrument panel. "The shields are down. We've got hull breaches all over the place and we're down to battery power."

"I need to see what's out there. Can you get that screen working, Lieutenant?"

"I'm on it." Harding tapped a console at a furious pace.

The bridge lights dimmed. "Try not to lose the mood lighting, Zaena," Blaylock said. Harding smiled weakly in response.

The viewer came to life in a brief burst of static. Stars shone whitely, no longer distorted by the subspace phenomenon. And something else was there as well. A shape...

"Can you increase the magnification?" Blaylock said.

Harding nodded. The lights dimmed further and the half-seen shape resolved itself into lines of hard metal. It was a large, toroid-shaped ship -- or perhaps it was a space station -- circled by dozens, or perhaps hundreds, of much smaller objects. Buoys? Service modules of some sort?

"Why didn't we notice all of this when we entered the system?" Blaylock said, turning toward Burdick and Harding.

Blaylock saw that Burdick's eyes were glued to the screen. Pointing a shaking finger, he said, "Maybe because they didn't want us to?"

Blaylock was unsurprised to see the ominous, double-bladed shape of a Romulan warbird rippling into existence on the viewer. I hate being right all the time, she thought mirthlessly.

The Slayton had to be well within the range of the decloaking warship's weapons. The Romulan vessel was more than twice the Slayton's size, and her disruptor ports glowed with menace. And the Slayton was dead in space.

But Blaylock told herself that the warbird's captain wouldn't harbor any hostile intent. With so little really known about the Geminus Gulf, why would the Romulans want to risk starting a war over it?

Then the warbird fired.

The Slayton lurched again, and the lights failed once more. Blaylock wondered how long it would take for the warp core to lose antimatter containment. And just what it was the Romulans knew about this place that she didn't.

The bridge flared into cerulean brilliance a moment later, followed immediately by more blackness. This time, the dark was absolute and eternal.

The Archimedes continued its descent through Chiaros IV's storm-tossed Dayside atmosphere. Zweller ignored the low conversational murmurs passing between the department heads and concentrated on his piloting chores. Though the inertial dampers succeeded in canceling out most of the turbulence, Zweller could still feel the deck shimmying slightly beneath his boots. And the structural integrity field was being taxed far more than usual.

Adjusting the viewer to compensate for the ball of white-hot plasma that now completely surrounded the shuttle's hull, Zweller quietly admired the savage beauty of the landscape quickly scrolling by below. It was a place of immiscible contrasts, irresistible forces in perpetual stalemate. It was a place he could understand.

As the Archimedes entered the nightward terminator, Zweller reduced the craft's velocity, lowering the hull temperature and making the plasma fires gutter out. He brought the shuttle down toward a range of cheerless brown mountains and arced into a northeasterly heading. In seconds, the craft cleared the peaks, and the relentlessly baked Dayside gave way to a fog-shrouded valley. Auroral flashes arced repeatedly across the sky, leaping the planet's everlasting twilight belt, momentarily linking day with night. The vapor dispersed as the ground grew nearer and unveiled a quiltwork of hardscrabble farmland and narrow roads. Small settlements and isolated dwellings hove into view and just as quickly passed away. A great cityscape glittered in the haze, barely perceptible on the northern horizon. It appeared to fade toward a tumble of dry hills and barren escarpments that extended into the planet's dark side as far as Zweller could see. Lights twinkled across the city's remote nightward periphery.

"Looks like we've found the planet's single worthwhile piece of real estate," Gomp said with a porcine chortle.

Finishing a long countdown in his head, Zweller thought: It's time.

An alarm light suddenly flashed on Zweller's console, and a klaxon brayed a warning. The tactical display at Zweller's left side came to life.

"What is it?" Roget said, sounding cautious, though not particularly alarmed.

"I think we're about to have some company," said Zweller.

"A Chiarosan honor guard?" Hearn ventured.

Zweller felt his jaw clenching involuntarily. "I... I don't think so."

"Shields up!" Roget shouted. "Red alert!"

Something struck the shuttle at that moment, making the hull reverberate like an enormous bell. The engineer and the doctor fell into a heap atop Liz Kurlan. Tim Tuohy, the head of planetary studies, helped Gomp get his hooves beneath him. Everyone scrambled back into their seats and activated the crash harnesses.

The shuttle rocked again, more violently than before, as though punched by a giant. His harness kept Zweller from being spilled from his seat. Though partly obscured by static, the tactical display showed a fast-approaching trio of small, aggressively contoured vessels. They appeared to be fighter craft of an unusual configuration. Zweller recognized them as Chiarosan.

"Status!" Roget shouted, trying to compete with the rumbling of the hull.

"Shields and weapons are off-line," Zweller said. "I can't keep anything working with all this atmospheric ionization."

A static-swept male voice, deep and harsh, emanated from the comm system. "Federation shuttle: You will follow our lead vessel's navigation beam into Nightside. Consider yourselves our prisoners."

Roget spat a nearly inaudible curse before replying. "We are here on a diplomatic mission at the invitation of First Protector Ruardh, the head of this world's duly elected government. On whose authority have you attacked us?"

"Had we attacked you, you would be dead," came the reply. "You are in the custody of the Army of Light. If you attempt to resist or flee, we will not hesitate to destroy your vessel."

Roget made a slashing gesture, and Zweller responded by temporarily interrupting the audio.

"Make best speed for the capital, Mr. Zweller," Roget said. "There are bound to be official patrols there who can drive these characters off."

Zweller shook his head emphatically. "They're right on top of us, sir. We'll never make it."

The shuttle lurched again and the hull braces groaned. Zweller watched the structural integrity telltale dip into the red. A near-miss, Zweller thought; a direct hit probably would have breached the hull and blown everyone out of the shuttle. The lights flickered as the battery-powered backup life-support system kicked in.

Roget's frown could have curdled milk. "You don't seem to be trying very goddamned hard, mister."

Raising an eyebrow, Zweller ignored the comment. "I don't think our welcoming committee enjoys being kept waiting, sir."

After pausing to glare at Zweller, Roget tapped a command into the console, relinquishing control of the shuttle's navigational computer to their captors. He turned toward the somber group in the seats behind him.

"Looks like we're taking an unscheduled detour, folks."

"Never a cop around when you need one," Gomp muttered. Nobody laughed.

The Archimedes abruptly banked and descended even farther. The shuttle barely cleared the hills beyond the sprawling city's nightward side as she continued into utter blackness, flanked by her "escorts."

Chiaros IV had no natural satellites and possessed a thick cloud canopy, conditions that made Nightside quite dark, except when the clouds were riven by lightning and auroral fireworks. The Archimedes' trajectory, however, stayed mostly within the swirls of the clouds blown in from Dayside, cover that made the auroras -- and therefore the ground -- difficult to see from the shuttle's windows. The few flashes of light that did enter the cabin merely served to prevent the crew's eyes from adjusting to the darkness. To the hapless occupants of the Archimedes, Nightside appeared more tenebrous than the inside of any tomb.

After crossing the terminator into night, the Archimedes flew for more than an hour, changing directions sharply several times, banking and spiraling. Whether because of atmospheric effects or damage sustained in the attack, the onboard instruments couldn't determine the shuttle's location or even its altitude. Sitting behind his useless control panel, Zweller realized that he might as well have been blindfolded.

Roget and the department heads somberly discussed their options, including whether or not they ought to open the weapons locker and put up some real resistance after landing. Though Gomp was the loudest proponent of the "stand-and-fight" notion, Zweller suspected that it was all rhetoric; he'd never met a Tellarite who didn't prefer a loud, abusive argument to actual combat. After everyone had spoken his piece, Roget announced that they were to forget about fighting their way out of this situation; after all, they had come to conduct diplomacy, not warfare.

They received a hail, and the crew cabin fell silent. "Prepare to land," said the harsh voice of their captor over the background of static.

A pattern of lights appeared on the ground, perhaps a quarter of a kilometer below the shuttle. Roget tried to turn the landing over to the computer, but it again failed to respond. Zweller tripped the manual override and began bringing the craft down, aiming for the center of the landing pattern.

A moment after the shuttle came to rest, the ground itself began to sink. Enormous mechanisms groaned as the surface beneath the shuttle lowered into a dimly illuminated subterranean chamber. Zweller watched on the viewer as a metal roof quickly rolled into place about eight meters overhead, shutting out what could be seen of the obsidian sky.

"I'll bet this place is completely invisible from the air," Gomp said, sounding impressed. "Very neat."

A bank of bright lights flared to life along the chamber's ceiling, revealing its enormous size. Several small fighter craft of the same type as their attackers were parked nearby. Perhaps twenty large, armed humanoids were taking up positions surrounding the Archimedes.

Kurlan and Tuohy both gazed significantly at the weapons locker, and then back at Roget, as if to say, This is our last chance.

"No phasers," Roget reiterated, and the rest of the human officers nodded their assent. Gomp spat a monosyllabic Tellarite curse.

Roget fixed a steely gaze on Zweller, but Zweller met it unblinkingly. "Commander Zweller and I will go out first," Roget said. "Unarmed."

Hearn opened the shuttle's hatch manually, then stepped aside. Roget walked through it to meet their captors. Zweller followed, the planet's slightly higher-than-Earth-normal gravity making his feet feel leaden.
