Erik
The Hanging Men
Acting on instinct, Erik grabs his bag and bandolier as the water washes him away. He hastily buckles them on before being thrown down the hallway by the torrent of water. Although he strikes the walls and metal doors, his armor seems to protect him from the worst of the blows.
Crashing into the large pool of water, he is drawn notably deeper than most of the others, no doubt on account of his heavy armor. Feeling the strange water sap his life force, Erik swims to the surface. Although a lesser man might've struggled under the weight of his armor, Erik navigated upwards with ease. Rising to the surface, he grabs hold of parts of the floor-now-wall, pulling himself some ten feet above the water line.
Now Erik is plainly visible to the others for the first time. Covered head to toe in thick metal plates, and nearly a head taller than most men, Erik appears much like a metallic construct. Wasting no time, he digs out a silken rope from his dangling backpack, searching for someway he could use it to heave himself up further above the encroaching water.
"How far do we need to go to make it out of the array?"
Even as he speaks, Erik is turning his head from side to side, searching for an escape route, or any more dangers that might spring themselves upon him.
