The Dark Lord

cut blocks of the wall's foundation, but they had been leached of power long ago.

Lightning blossomed, stabbing out from her hand as she moved her fingers in an old, old sign. The sky answered and brilliant blue-white thundered against the golden wall, ripping through gossamer, shattering delicate patterns, a sledge crashing into new-blown glass. Zoe gasped in surprise—she had never thrown such power before! A dark current boiled in her mind, flooding her senses, threatening to burst free of the binding of flesh and will. An enormous pressure crushed against her and Zoe screamed in panic, feeling the might of the Lord of the Ten Serpents flow through her.

Another bolt flashed across the narrowing distance and the golden wall shuddered. Below, in the fight still raging along the wall, men screamed in despair, throwing themselves to the earth. Wooden towers wicked into flame, pitch exploded in its barrels, scattering smoke and living green fire everywhere. Zoe felt the Roman thaumaturges reel back, stunned. Of her own accord, she struck—fist twisting into a pattern to rip the earth, to sunder stone, crack wood.

The shadow arm moved in unison with her will and an ephemeral fist smote the earth.

Khalid, still on his hands and knees, flinched back. A huge, towering figure—two hundred feet tall, his mind gibbered—strode out of the desert, skin black as night, face that of an enormous jackal, white fangs a tall man's length, red lips hideous against the ebon flesh, eyes blazing crimson. Lightning flashed, rocking the air with a stupendous boom and splintered across the sky, flooding over some invisible wall rising up from the Roman fortifications. A long, ringing tiiiiing followed, as if a stupendous crystal shattered. The Arab threw himself down the slope, thorns ripping his flesh, his arm crunching against another stake.

Behind him, the actinic glare of lightning flashed along the wall, driving men back with terrible heat, incinerating those still struggling on the rampart. When Khalid stopped rolling, the entire slope of the earthwork was on fire, wooden stakes and thornbush alike billowing flame and smoke. The titanic jackal wavered, its edges dancing with heat haze. It smashed a fist down into the center of the Roman wall. Khalid flinched and the earth jumped with an enormous crunch. A huge blast of dust roared up, logs and clods of earth flying in all directions.

For an instant, Khalid saw the sky distort, burning sparks licking off in jagged paths through the air. Pressure beat against his ears and he gasped for breath. The air itself bent, throwing insane reflections of the sky, the ground, running men. The smoke-jackal bent a vast dark shoulder, pressing at the empty air, an enormous foot grinding across the earthen rampart, splintering wood and crushing soldiers already stunned by the blasts ringing in the air into a crimson smear.

Thunder boomed out of the west and Khalid—still cowering at the base of the slope—saw blue-white lightning leap down from the sky, flaring across the jackal's shoulder and chest. The thing howled, ebon flesh incandescent where the blast had lit, then smote the air with a fist, then again. Tongues of fire slashed out of the west, haloing the monstrous creature's head with smoke. Still the air bent and Khalid realized some kind of invisible barrier was deforming under the jackal's attack. He crawled away from the smoldering brush, then remembered the blade of night lay somewhere behind, lost among the flames.

'Curse it!' he growled, hurriedly wrapping the tail of his kaftan around his face, leaving only a slit for his eyes. The fires were still sputtering, flames licking up here and there, curling bitter white smoke from the ashy ground. The young Arab scrambled up the slope, casting about wildly, desperate to find the sword of the city. His skin flushed with sweat. Where are my people?

Together! roared Dahak and Zoe's mind submerged in a rushing black flood. The hidden world convulsed with stabbing white bolts of power. The Roman thaumaturges were weighing in, furious in their assault, bending the earth and sky to crush the shadow creature mired against the golden wall. Zoe felt the serpent curse in rage, then she, Arad and Odenathus moved as one, colossal arm swinging back as they bent their power against the tattered, deformed pattern. Dimly, though the helices of fire slamming into their own wards, she perceived a huge group of desperate minds—sixty? seventy?—hurling flame, lightning, every scrap of power against them.

The shadow's vast hands tore into gossamer gold, fingers wrapped in lightning, blazing with ultraviolet, and Dahak spoke a word. The sound reverberated in the smallest stone. Men fell dead for miles around, though others staggered and lived. The shining wall froze—constant motion stilled—and Zoe saw a vast overlapping matrix of geometric forms congeal from hurrying, inconstant, undefined motion. Dahak bellowed, forcing his strength through the shuddering form of Arad, and the golden ice shattered violently, breaking away in dizzying fragments from a pinpoint blast of will.

The opposing minds vanished from Zoe's perception, blown aside like leaves ripped from the trees by a titanic gale. The golden wall crumpled, breaking into brilliant shards, each one splintering into smoke, then nothing. The jackal strode forward, shadow long upon the land.

Khalid clung to the earth, feeling mud and brick buck under him like a wild horse. A log fell past, rolling down the slope. A huge ripping sound split the sky, then a shattering boom, followed by rushing, forge-hot wind. Khalid cowered, digging into the loose earth. A colossal footstep slammed down, followed by the screams of men. The Arab looked up and saw, not more than a yard away, a bronze-bound hilt gleaming in the wreckage.

'At last!' he croaked, crawling forward to seize the hilt with both hands. The blade of night sighed free from the earth and Khalid felt his heart soar with relief. The blade was unharmed! He rose to his feet, staring to the north. The head and shoulders of the jackal loomed up, wrapped in billowing smoke and dust. The thing's face was lit with flames. Stone splintered under its tread and Khalid saw a huge section of the Roman fortification was gone, cast down, only rubble and corpses remaining.

'Forward!' he screamed, pointing with the sword. 'To me, Sahaba! To me!'

In the canal bottom, those men who still lived picked themselves up, caked with mud, streaked with crimson. Khalid ran along the slope, dodging fallen timbers, leaping across the dead. His men saw him, recognized the shining ebon blade in his hand, and they raised a tumultuous shout.

'The Eagle!' they cried, running forward, spears raised, catching the sun cutting down through the dust. 'The Eagle!' Thousands of the Sahaba, shaking free of surprise and fear, flooded forward into the breach.

'That's torn it!' Sextus picked himself up from the road. An earth tremor had rippled the length of the wall and the military road, shaking open huge cracks in the earthwork, jumbling the logs laid down to provide a mud- resistant roadway. 'Are you hurt?'

Frontius rolled over, unable to stand. His face was a tight mask of pain, gnarled hands wrapped around his ankle. 'Aiii... I think it's broken.' The engineer gasped. Sextus knelt down, fingers tugging at his friend's boot. Frontius turned a funny color, lips going white. 'Don't...'

Sextus stopped messing with the laces, then slipped a knife from his belt. The heavy military leather resisted for a moment, then parted with a scraping sound. Sextus worked the remains of the hobnailed boot free, jaw clenching as he saw a purplish-black bruise around Frontius' ankle and shin. 'It's bad,' he bit out.

The earth quivered again and now a rolling series of crashing sounds, interspersed with thunderclaps, shook the air. Grunting, Sextus got a shoulder under Frontius, then staggered to his feet. The other engineer, hanging upside-down, croaked in alarm, then convulsed, vomiting. Sextus ignored the slick wet feeling on the back of his bare legs. He cast a look behind him, over his shoulder.

Smoke obscured the center of the Roman line. Black smoke billowed up from burning, damp wood. Clouds of dust were interspersed with the smoke and leaping flames intermittently lit the haze. Sextus blinked, unsure of his own eyes. Lightning jagged and ripped through the smoke, briefly illuminating something huge moving at the center of the conflagration. The engineer cursed, suddenly realizing what he was looking at. The distortion of scale was too vast to easily comprehend.

A colossal figure a hundred yards high plowed out of the smoke. Mangonel stones smashed against its chest, bursting with green fire. Clouds of arrows leapt up from the ground, clattering away from ebon-hued skin. A vast jackal head appeared from the smoke. Fire burst upon it like spring flowers—blossoming in a hundred radiant hues, then vanishing again. The thing chopped an enormous hand down and the earth shook. Sextus staggered, shifting his balance. A flare of unnamable color burst from the moving fist and siege
