sprawling wetlands. The junction of the marsh and the fortified walls was held by offsetting way forts, the two dry canals and—behind the entire defense—the camp of the First Minerva, their own veteran Legion.
'You think they'll try and break through, to swing south of the town,' Frontius said. 'Cutting us off from retreat, save over the Nile bridge. We'd be bottled up in Pelusium itself.'
Aurelian nodded, but he did not seem convinced. 'There's no reason to besiege the town—not if they can isolate us here and go around. Then we'd be forced to abandon the entire position, to fall back and defend the delta and Alexandria. The bridge is narrow—we'd take some time withdrawing across the span. So—I want the two of you at the southernmost mirror tower by daylight. If the Persians break across both ditches, I want the dam opened.'
Sextus saluted, acknowledging the order. 'Should we give the men in the forward works time to fall back across the second canal, if the first wall is breached?'
Aurelian's lips quirked into a grim smile. 'Once the dam is opened, the canals will flood all the way to the sea within two hours. Time enough for the Persians to get their neck out of the trap. But I will not be there, Sextus. You will have to use your own judgment. Of course, when I send the signal—'
'—we will obey instantly, Caesar!' Frontius managed a chuckle, rubbing the back of his neck.
'Good. Now, go.' Aurelian turned away. Servants were waiting with his armor, a single-piece breastplate of Indian steel, etched with the eagle and laurel crown of Rome and designed to fit over a mail shirt. Other slaves held his long single-edged cavalry sword, a plain, battered helmet, and a broad leather belt. Both engineers saluted, then hurried out. The southern mirror tower was five miles away, down roads sure to be crowded with men moving up to the fortifications.
In the east, the sky was still dark, without even a hint of the coming sun.

Zoe knelt on the rolled-up edge of her cloak, among a field of stumps, beside the old Roman road. Lines of men in armor tramped past along the raised highway, starlight glimmering on their helms, each man watching his file leader, following the bare gleam of hooded lanterns. The armies of Persia, the Decapolis and the Arab tribes had been in motion for more than two hours. Zoe shut the sound of boots and sandals on stone and sand out of her mind, fingertips pressed to her temples. She let her mind settle, let her thoughts calm.
The sorcerer crouched in the fallen orchard as well, though he wore the tall, powerfully muscled shape of his servant, Arad. The iron mask, the jackal snout, were bent as if in prayer. Zoe turned her attention away, banishing a familiar distraction.
The dodecahedron swelled, split apart, fractured into dozens of similar geometries, then split again. A flood of shining motes darted away and Zoe looked upon the hidden world, blazing bright.
The columns of soldiers shone with ruddy light, the road a dull blue streak, the distant fortifications of the Romans a shining golden wall. Immediately to hand, the shape of the jackal was a black void, without the inner fire of a human soul or even the flickering pattern of an animal or bird. Behind the sorcerer, beside Zoe, Odenathus was also preparing himself, a steady forge-red pattern, all confidence and strength.
Zoe grimaced, though her waking mind continued its plunge into the matrices of the hidden. A pattern of defense built around her, swirling with half-seen glyphs and words of power. She reached out to Odenathus, felt his familiar thoughts, then the shield of Athena was complete, a steadily burning blue-white sphere. One edge of the pattern enclosed the jackal, though the ebon power within the dead shape distorted the smooth surfaces, making them bend and dip like cloth pressed down by a leaden weight. The Palmyrene woman concentrated and the shield sluiced away, leaving the jackal alone and outside its aegis. The blue-white dome strengthened.
Zoe let her awareness recede a step, allowing her physical senses to flood back into focus. Her skin tingled with the chill of the night; her ears heard the soft wail of horns, the quickening steps of men on the highway, the snort of horses.
His will gripped them like a vise, holding them powerless. Zoe felt darkness flood into her, felt the Queen flee deeper into the inner void, felt her limbs twitch with Dahak's intent, nerves burning with fire. She hunched down, bowing at his side.
She froze, breath coming in short, sharp gasps. Dismay rose in her, icy water spilling into a shattered hull.
With a tremendous effort, bringing to mind a calming meditation, she drove the thoughts of murder and insurrection from her mind. A cold clarity settled over her.

Sextus jogged south, measuring his stride, conserving his breath. Frontius was lagging, still cursing under his breath, anger radiating from every pore.
'Dick-licking bastards! How could they steal our mules?'
Sextus ignored his friend, swerving around a wagon rumbling past. The road on the second wall was crowded with men; cohorts tramping past, torches held overhead, wagons filled with bundles of arrows, coffers of sling stones, more spears, healers in white cloaks, caduceus staves over their shoulders. The engineer pushed through a crowd of Blemmyenite archers, feathered plumes dancing over shaven heads. Sextus broke through into a clear section of the road. Furious himself, he glanced over his shoulder for Frontius. 'Don't waste your...'
The eastern sky was glowing a pale pink. Tiny, crescent-shaped clouds caught the dawn as she climbed up over the rim of the world, burning like spilled, molten gold.
'Shit!' Sextus scrambled up the nearest steps to the fighting wall. A dim light spilled across the land, picking out the roofs of the watchtowers on the first wall, ignoring the deep cavity of the dry canal. Frontius clambered up, puffing, unable to speak, his breath spent. Sextus wiped his forehead, fingers brushing against chilled metal. He stared out across the sprawling fortifications.
The edge of the sun peeked over the horizon, a single burning golden dot.
Sextus swallowed. The world seemed very quiet, still, without motion or sound.
