"Reverse engines, Karn!"
The ship's power core went silent. The hatch to the engine room flung back. Steam billowed out above the deck. From that hissing cloud emerged the silver mass of Karn. He climbed laboriously from the hatch and strode with heavy intent toward the forecastle.
"Karn! What's happening?"
"The power cores," he said, leaping from amidships to the forecastle. His legs drummed the deck. "They're drawing each other together like a pair of magnets. Every time we fire up our engine, it pulls us deeper. The only way to get out is to shut down their engine."
Eyes wide, Gerrard said, "And how do we do that?
Karn gestured toward the prow. Thick metal curled away from the ship's hull. "Give me a door."
Wordlessly, Gerrard nodded. He swung his cannon toward the armor of the Phyrexian ship and squeezed off two shots. Red rays melted air and then metal. It dripped through the breach, revealing the cross section of a corridor.
Dipping his head, Karn vaulted over the prow rail and in through the red-hot hole. His feet struck a floor of metal grate. The sound echoed both ways down the long corridor and was answered by more feet-Phyrexian feet. Gibbering hungrily, monsters scampered down the passage toward the intruder. They loped on all fours like wolves, though their bodies were scaly and their mouths could have swallowed a wolf whole. The monsters converged on Karn and leaped, howling.
Rearing his fist back, Karn hurled a roundhouse at the first beast. Silvery knuckles cracked through rows of teeth. Enamel tumbled in the creature's mouth. Karn's hand rammed down the monster's throat. It closed its bite on him, hoping to sever his arm.
Karn whirled, bashing the second attacker down with the writhing body of the first. He withdrew his arm from the creature's throat, bringing with it a handful of innards. A third hound died beneath a stomping foot, and a fourth with a broken back. The last beast leaped on Karn and bit his head, trying to take it off. Sliding hands into the chewing jaws, Karn opened them wider than they ever should have opened.
He took a moment to make sure all the beasts lay destroyed and then shouted toward Weatherlight, "A door for me is a door for them. Defend this breach until I return."
Gerrard's sardonic face shone above the smoking barrel of his cannon. "Aye aye, Engineer!"
Karn looked down, considering the dead. At one time, he would not fight, would not harm a soul. Now, Karn had just torn five creatures apart. Perhaps these were mere beasts, but smarter foes would lurk ahead. They would realize what he was trying to do and would fight-and would die.
"Better them than my friends," Karn thought aloud. Without another word, he headed down the passage toward the ship's power core. He could sense its emanations. There was an uncanny kinship between Karn's body and the cruiser. Even the runes carved in the ships inner halls resembled the characters scribed on Karn's chest. Living metal surrounded him, half designed, half grown. The dark corridor had an organic logic, more like a vein than a hallway. Each footfall seemed a heartbeat. For a moment, the passage dissolved, replaced by another from long ago. It was a white hallway. He walked beside a young man, a boy really, though a genius. Beneath his bald forehead lurked impish eyes and a slightly cruel smile. It was no Gerrard. His skin was too dark. It was another friend, Karn's first friend. He struggled to remember a name. Ladlepate? Arty Shovelhead? No, those weren't names for the boy, but for Karn. The boy's name was… Teferi?
Karn surfaced from his waking dream in the midst of a fierce fight. Phyrexian shock troops-more machine than creature-swarmed him. Their human heads and torsos were deeply ensconced within a framework of artifact mechanisms. On draconic legs, they ran. With scythelike arms, they fought. Their horns could impale three men abreast, but they could not impale Karn.
Karn patiently grabbed their arms and ripped them loose. It was the treatment he had given Tsabo Tavoc and now to her children.
The beasts fought on. They couldn't destroy him, but they could halt his advance until more troops arrived. That would be enough to doom everyone aboard Weatherlight.
Growling, Karn knocked down a trooper blocking his path. It landed on its back. Karn stomped on the thing's chest. Metal failed. Flesh oozed out like paste from a tube. This was worse than killing the hounds. These creatures had once been human.
Karn finished the wretched work. Glistening-oil coated him from feet to hips. It poured in a regular rain through the grating. Trying to shut the sound out of his mind, Karn strode deeper. The engine core called him.
Again, the tunnel closed to a single point. It opened in another place and time, but the circumstances were the same. He was killing Phyrexians to defend a friend.
This was a true friend, not like Teferi. This was Karn's first true friend. Her name came ringing back through his body like the toll of a bell. Jhoira. She had saved him from loneliness, and he had failed to save her from Phyrexians. She lay, bloodstained and broken, on the floor of her cell there at the academy (the academy?), and Karn fought in rage against the negator that had slain her. He was not really defending Jhoira, for she was already dead. He was avenging her, bloodily, with a sense of righteous rage.
The killing strokes of that bygone day-how long ago?-elided with the killing strokes Karn would swing in mere moments.
He had reached the engine room-a huge arched chamber. At its center was an enormous engine, ten times the size of Weatherlight's. Buttresses of Thran metal braced a sloping manifold in foot-thick steel. Within that framework surged energies that glowed red-hot. Power coursed from the main engine into countless arteries. Auxiliary powerhouses crouched on the floor around the mother machine. The air throbbed with noise. The engineers were utterly unaware of Karn's approach.
They were almost human-tall, thin, with weighty brains and narrow digits. Their bodies bore slender metal implants. No doubt these were compleated Phyrexians, but they had not been much modified from the human stock whence they had been drawn.
Without pause, Karn strode to them. They died like birds in his grip. How could he do this? Karn, who had stood by while Tahngarth was tortured in the Stronghold? Karn, who had allowed Vuel to make off with Gerrard's Legacy? Karn, who had failed Jhoira in her hour of greatest need?
No, he had not failed. In fact, he had turned back the hour, had turned back even the day. He'd gone back in a time machine-strange memories!-to kill her killer, to save her and the whole academy of Tolaria.
Tolaria! But Tolaria was a myth, less real even than its master Urza.
If Tolaria was a myth, why did Karn remember its destruction? To save the academy-no, to save Jhoira-he had pushed the time machine to its limits and destroyed it all.
To save his one true friend…
The Phyrexian engineers were dead. Gerrard and the others would be dead too unless Karn shut down the engine. There were countless ways, but as Karn read the configuration of power cells, he knew the main core would always restart itself. There was only one way to shut it down permanently.
Striding along the oil-stained flank of the engine, Karn shoved levers upward. Power mounted. One cell began to whine and then the next. Mana superfluids boiled violently. The rumble crescendoed to an angry wail, then a deafening shriek.
It was enough. Karn turned. He ran back the way he had descended. It was an easy trail, marked with bodies. Seventeen engineers beside the power core, twelve shock troops in the passageway, and there, ahead, where clear sky shown through a hull breach, five vampire hounds.
Behind Karn, the core went critical. White-hot fire engulfed the engine room. It burst the walls outward. It flung the doors from their hinges. Pure energy bounded up the corridor behind Karn.
He ran. His feet clanged on the grating. From heat alone, the vampire hound bodies burst into flame. Their glistening-oil blood made a wall of fire before him. White power behind and red flame before, Karn hurled himself through the hull breech. He roared. His bloodied hands burned as he hurtled through the air.
