They had already lost the runner twice that morning. Cael hated losing.
Morning market crowds packed the street from stall to stall. Vendors shouted prices over one another while the smell of citrus, hot bread, and frying oil drifted through the cold air. The thief cut through it all like he belonged there, slipping between bodies with casual precision. Shoulders turned just in time to avoid contact. Feet never slowed. No panic. No stumble. Every stride carried the calm rhythm of someone enjoying the chase.
A grin spread slowly across Cael's face.
Finally.
Ten strides off to the left, Riven watched the city instead of the runner. Sightlines first. Windows above the street. Fire escapes. Loose laundry lines. Corners that narrowed movement and roofs that could collapse under sudden weight. The path ahead was not random. Whoever planned the route had guided the pursuit deeper into tighter streets where a mistake would break stone and bone at the same time.
The runner angled sharply past a spice cart. Riven called out across the crowd.
He is steering us.
Good. Cael vaulted a stack of crates without slowing. I was getting bored.
Metal clinked faintly at the thief's belt while he cleared a fruit stand in a smooth leap. A flash of polished steel caught the morning light before vanishing again into motion.
The shine tugged at memory. Riven's new knuckle plate. Weeks of skipped meals had paid for that polished edge. Pride hidden beneath practical silence.
Boots slammed onto the fruit stand an instant later. Apples burst across the street as the structure collapsed under Cael's weight. A woman screamed. Someone swung a broom that caught nothing but empty air. A shopkeeper began shouting about damages before realizing the damage was still running.
Heat rolled beneath Cael's skin. Restless. Hungry.
The runner glanced over his shoulder.
A sharp smile followed.
He wants space. Riven's voice carried through the chaos. Stop feeding it.
Then stay close.
Instead of following the alley turn, Cael drove shoulder first into a brick wall beside it. Impact thundered through the street. Mortar exploded outward while heat pulsed violently through the stone. Shutters rattled along the building front. A second floor window cracked under the sudden force. Somewhere farther down the street a dog began barking in alarm.
Pain shot through spine and ribs.
Laughter followed anyway.
That was faster.
That was loud, Riven answered while stepping through the settling dust. And unnecessary.
It worked.
Iron rang above the street as the runner climbed a fire escape two buildings away. Wind tugged loose banners between rooftops. Fabric snapped and twisted like warning flags.
Cael sprinted straight at the wall.
Three vertical strides carried momentum upward. Brick fractured under each step. Fingers caught a broken ledge and hauled the rest of the climb into motion. Crumbling stone scraped across palms and knuckles while loose grit embedded itself beneath skin.
The rooftop greeted the climb with shifting tile and cold wind. Boots slid half a step before balance returned.
The runner stood waiting across the roof.
Lightning crawled across both hands in thin blue threads that slowly tightened into spiraling arcs. Sweat glistened along his temple now. Breathing had grown heavier. The chase was no longer a game.
Good, Cael said while advancing. Interesting.
The first bolt tore through the air.
Down.
Instinct dropped Cael flat against the tile. Lightning detonated behind him in a spray of shattered stone. Fragments sliced across cheek and jaw while the sharp smell of ozone filled his lungs.
Movement returned immediately. A roll carried him upright just as another strike came faster and closer.
Forward.
Heat flared outward from both arms in a violent surge. The lightning bent slightly under the pressure. Not enough to avoid contact completely but enough to keep the strike from tearing straight through muscle.
The impact rattled ribs and shoulder. Fingers twitched as shock crawled through nerves.
Worth it.
A heated fist drove toward the runner's ribs. Leather caught the strike instead of flesh, yet the force still staggered him half a step. Lightning snapped again at point blank range. White current locked muscles long enough to freeze the next movement.
The tremor began there.
Not from the city.
From inside Cael.
Nerves misfired while heat surged too high and too quickly. Familiar warmth sharpened into something unstable. Forearms burned wrong. Control slipped along the edges of every motion.
Boots struck the roof behind him.
Riven landed beside the fight with quiet precision. Sigil lines cut sharp geometry through the dust and wind.
You are overextending. Again.
I am managing it.
You are not.
The runner broke contact and sprinted across the rooftop line. Breathing had turned ragged now. One arm held tight against the ribs where the punch landed. No more smiling. Only calculation.
A gap between buildings opened ahead.
Cael jumped without hesitation.
Stone cracked beneath the landing as weight struck harder than intended. The roof sagged slightly before holding. Reserve burned faster than expected. Power still existed but shape had begun to fray.
Another leap clipped a chimney. Loose brick shifted underfoot while balance faltered.
For one brief second the world became open air.
Hands caught the roof edge at the last instant. Shoulder screamed as body weight dragged downward. Dust and grit rained into the alley below like falling ash.
Stabilize your breathing, Riven called from above.
Air scraped into Cael's lungs while he pulled himself back onto the roof. The tremor crawled slowly from wrist toward elbow. Small movement. Persistent.
The runner noticed.
Lightning gathered again, this time forming a full arc instead of scattered bolts.
Defensive heat came too slow.
The strike slammed directly into raised arms. Force exploded outward and sent Cael skidding backward across the rooftop until a low ridge stopped the slide with a cracking impact.
Air vanished from his lungs.
Vision narrowed.
Heat escaped uncontrolled in a sudden outward pulse. Windows shattered along the street below. A man in the alley shouted and dove behind a wagon.
The runner flinched at the noise.
Riven moved at that exact moment.
Sigil light ignited beneath fleeing boots. Binding geometry rose in narrow bands that wrapped the runner mid stride. Momentum twisted sharply downward before redirecting into a controlled fall.
Cobblestone ended the pursuit with a hard final impact.
The chase stopped there.
Boots touched the alley floor moments later. Balance wavered once before stubborn pride forced the body upright. Breathing refused to settle. Hands shook more than pride wanted anyone to see.
Perfect, Cael said while forcing a grin.
Riven studied the cracked wall behind them.
Reserve lasted less than three minutes.
I am fine.
You are depleted. Output spikes whenever control slips.
Sirens echoed through nearby streets as arcane response teams reacted to shattered windows and fractured stone.
A hand caught Cael's wrist briefly.
Pulse quick. Skin overheated.
Your rhythm is unstable.
It always is.
Not like this.
The grip released.
The tremor remained.
The captured runner watched the exchange with shallow breathing and wide eyes.
You fight like you want to die.
Cael crouched until both stood eye level.
No. The answer came quiet. I fight like I do not want to.
Silence followed.
Something tightened in Riven's expression that had nothing to do with tactics.
An arcane carriage turned into the street moments later. Blue sigils burned across reinforced panels while wheels hissed against wet stone.
We move.
Cael rolled his shoulders once and forced posture back into something looser.
Next time I pace it better.
You will listen.
Side streets swallowed both figures just as officers flooded the block. Broken brick and shattered glass marked the path of the chase. Excess damage perhaps. Nothing that suggested instability.
Laughter returned while running.
Thinner this time.
The tremor still had not stopped.
Riven had felt exactly how close collapse had come.
That worried him far more than the lightning ever could.
