Pursuit

Straight ahead, there was a metal train track embedded in the floor.

It seemed as if it was an escape route.

"Shit. When will this facility end?" Draven muttered, irritation creeping into his voice.

They had been running for over an hour, but the endless metal corridors stretched like a long tunnel.

As they did so, the atmosphere shifted.

The further they ran, the colder the air became.

Belle and Deka rubbed their arms, shivering.

"Hey, this isn't normal," Deka muttered. "It wasn't this cold earlier."

As they reached an intersection, they skidded to a stop.

There are two paths to take.

To the left there's a heavy steel door.

Frost formed along its edges. 

The temperature dropped significantly in that area.

Bella and Deka panted from running, catching their breath.

"Which way?" Belle asked.

Draven stared straight ahead.

He knew Commander Dex and Duke Marcus had gone that way.
