Then, in the sky above the castle, Kylar saw a long arc of blue-green flame. He started walking.

The wytches looked pleased. They conferred with an officer, who started barking orders. One of the Khalidorans raised a torch and waved it twice. Lefty and Bernerd took torches of their own, walked to either side of the bridge, and waved twice.

All clear. Right.

Kylar drew Retribution. As it hissed out of the scabbard, the bashers turned. Lefty blinked and leaned forward. With the torches in their hands blotting out their night vision, all they saw was a thin strip of dark metal bobbing and floating through the air. Then it moved with terrible speed.

In a moment, both men were dead. Kylar replaced the torch he’d plucked from Bernerd’s hand and checked the men on the barges. They had already formed up and were walking, single-file, up the narrow switchbacks that led to the bridge.

Grabbing the keys off Bernerd’s body, Kylar opened the gate and slipped through the inset door. The crank and the release for the river gate were there. The gate itself was simply a massive, counterweighted portcullis that could drop into the water. In this case, onto a ship.

Kylar threw the release. The river gate dropped two feet—and didn’t crunch. It clanged. Kylar looked over the side of the bridge. The river gate had slammed down onto magical stops that glowed and sparked in the darkness. Wytches were on the deck of the first barge, shouting.

He ran into the guard station. There was a fire pit with a cauldron full of stew, cooking paraphernalia, a helmet, several cloaks, chests for the men’s personal belongings, and a set of knucklebones on the low table. There was a closet full of old broad carpets stuffed in fat buckets.

Kylar rushed out of the guard station. Surely the king wouldn’t have left his military bridge with only that defense. The pilings of the bridge were wood sheathed in iron—impervious to fire. The sheathed wood still got wet, but couldn’t breathe and release the water it absorbed, so every beam rotted within years and had to be replaced.

Why would the king be so particular about fire?

And then Kylar saw why. Along either side of the bridge were long wooden beams set on pivots. On the end of each beam was a huge clay globe as wide as Kylar was tall. At least part of the clay was molded over iron because a mooring rope was tied to an iron loop at the top of the globe. Several small handles also protruded from the sides.

Pulling on one handle, Kylar found a bracket. As he slid it out, a wash of oil fumes swept over his face.

It took him several precious seconds of staring at the entire contraption to understand. The arms would swing out over the side of the bridge, holding the globes full of oil, then drop them onto any boat passing underneath—and hopefully set it on fire in spectacular fashion.

He rushed back to the gate and grabbed the torches the guards had been carrying. He closed and locked the gate quickly. The advance party of Khalidorans were almost to the bridge.

What am I doing?

The first barge was just starting under the bridge. There was no time. Kylar kicked a safety latch holding the beam in place and pushed on it. It didn’t move. He stumbled and almost tripped over taut ropes at his feet, cursed, and flung himself against the beam again. Hadn’t the damned soldiers ever greased this thing?

Finally it occurred to him to use his Talent. He felt power flowing through him—he could lift a wagon on his back. He pressed against the beam and could feel himself shimmering, the ragged black covering and uncovering his skin as he redirected his Talent.

If I’m lucky, they won’t even know I’m here until it’s too late.

A ball of crackling green wytchfire flew over the globe, missing it by a yard. Yells sounded from below. Whether the wytches saw Kylar or just his torches, they weren’t pleased.

Kylar pushed against the beam, but with nothing to brace his feet against, he just slid across the planks. The beam barely moved.

A ball of wytchfire caromed off the globe and ricocheted up into the sky. Kylar ignored it. Something white was blooming above the deck of the barge—now directly under him. A small creature took shape in front of a red-haired wytch and started flying up like a hummingbird. The wytch chanted, his vir-marks thick with power, directing the creature.

Kylar heaved and the ropes at his feet tripped him hard.

The homunculus took shape as it zoomed toward Kylar. It was small, barely a foot tall, and pasty pale. It wore the likeness of the red-haired wytch like ill-fitting clothes. It landed on the globe gently and then rammed steely claws into the iron as if it were butter. It turned to Kylar and hissed, baring its fangs.

Kylar scuttled back and almost fell off the edge of the bridge.

A concussion thudded below. The air in front of the red-haired wytch rippled like a pond absorbing the shock of a thrown rock. Something was moving as if it were just under the surface of the air. Something huge. Reality itself seemed to be stretching—

And tearing. Kylar saw hell and rushing skin as reality itself ripped under the pressure of the wyrm’s passage.

It was coming for him.

Twenty feet from him, reality frayed and tore. Kylar had one glimpse of a gigantic, lamprey-like circular mouth. It seemed to throw its mouth inside out in a spiny cone. Then the narrowest ring of teeth hit the homunculus and the teeth snapped in the opposite direction, tearing into the pasty creature. Each successive circle of teeth pulled and snapped onto everything surrounding the homunculus with hideous strength, the cone inverting, sucking everything in.

The last, widest row of teeth snapped closed on the widest part of the iron globe and the pit wyrm whipped back into its hole as suddenly as it had emerged. The air rippled again and then faded as if nothing had happened.

The homunculus was gone. So was three quarters of the globe, clay crunched and iron sheered off as if it were lard. Oil dribbled onto the water beside the barge. The soldiers cheered. The first barge had passed the bridge, and the second barge was just emerging.

Feeling weak, Kylar scooted back and almost fell on ropes again. He cursed loudly. Then his eyes followed the ropes. They were connected to a pulley system—attached to the beam.

“I’m an idiot!” Grabbing a rope, Kylar pulled it hand over hand as fast as he could. The arm supporting the second globe swung out over the side of the bridge smoothly and easily. Kylar heard a yell, and two green missiles flew past.

Next to the pulley, there was another rope. Thin. Probably important.

Kylar yanked it and the beam holding the clay globe suddenly dropped. The globe dropped with it. For a moment, Kylar was afraid that he’d just dropped his only weapon straight into the water, but the mooring rope swung the globe like a pendulum a foot above the river. The globe slammed into the second barge at the waterline.

There was no explosion. The side of the boulder that struck the barge was iron beneath a patina of fired clay. It burst through the side of the barge as if the hull were birchbark and blasted through crowded ranks of highlanders.

The rest of the globe was clay. It disintegrated. The oil that filled the globe splashed violently over men and their gear, soaking the wood decks.

Kylar looked at the barge from above. A nice hole gaped at the waterline and the men inside were screaming, but he’d hoped for something more impress—

BOOM!

The barge exploded. Flames leaped out of the hole the globe had made and tore it to three times its original size. Fire burst from the portholes. The doubled and redoubled screams of men were swallowed in the sudden roar of flames.
