Gunfire.

Wax responded immediately. He Pushed himself sideways off an iron gate, then ducked in a roll. He came up and reached for a Sterrion with his right hand, his left steadying the shotgun in its sleeve in his coat.

He peered into the night. Had his thoughtless shotgun blasts drawn the attention of the local constables? The guns fired again, and he frowned. No. Those are too distant. Something’s happening.

This actually gave him a thrill. He leaped into the air and down the street, Pushing off that same gate to get height. He landed atop a building; this area was filled with three- and four-story apartment structures that had narrow alleyways between. How could people live without any space around them? He’d have gone mad.

He crossed a few buildings—it was handy that the rooftops were flat—and then stopped to listen. His heart beat excitedly, and he realized he’d been hoping for something like this. It was why he’d been driven to leave the party, to seek out the skyscraper and climb it, to run through the mists. Back in Weathering, as the town grew larger, he’d often patrolled at night, watching for trouble.

He fingered his Sterrion as another shot was fired, closer this time. He judged his distance, then dropped a bullet casing and Pushed himself into the air. He’d restored his weight to three-quarters and left it there. You needed some weight on you to fight effectively.

The mists swirled and spun, teasing him. One could never tell which nights would bring out the mists; they didn’t conform to normal weather patterns. A night could be humid and chill, and yet not a wisp of mists would appear. Another night could begin dry as brittle leaves, but the mists would consume it.

They were thin this night, and so visibility was still good. Another crack broke the silence. There, Wax thought. Steel burning with a comfortable warmth within him, he leaped over another street in a flurry of mistcoat tassels, spinning mist, and calling wind.

He landed softly, then raised his gun in front of him as he ran in a crouch across the roof. He reached the edge and looked down. Just below him, someone had taken refuge behind a pile of boxes near the mouth of an alley. In the dark, misty night, Wax couldn’t make out many details, but the person was armed with a rifle resting on a box. The barrel was pointed toward a group of people down the street who wore the distinctive domed hats of city constables.

Wax Pushed out lightly from himself in all directions, setting up his steel bubble. A latch on a trapdoor at his feet rattled as his Allomancy affected it. He peered down at the man firing upon the constables. It would be good to do something of actual value in this city, rather than just standing around chatting with the overdressed and the overprivileged.

He dropped a bullet casing, and his Allomancy pressed it down onto the rooftop beneath him. He Pushed more forcefully on it, launching himself up and through the swirling mists. He decreased his weight dramatically and pushed on a window latch as he fell, positioning himself so he landed right in the middle of the alleyway.
