Knight
Something flops onto Tim's hand as he scratches his head... it's an ear, and it's fuzzy and long. He can actually feel it touching his hand and hair. As he walks down the corridor, there don't seem to be any other people around. However, he can hear the rushing of water on either side of the tunnel. He comes across another maintenance door, and the rushing water sound comes from the other side too.
Evra
The water equals out the pressure from outside, making it an easy swim across the bridge. The door opposite is stubborn, and doesn't open until Erik is completely submerged in the chilly, tingly water. He gets spilled out into another metal chamber with the same red yellow and green lights as the other. This chamber has open vents already in the floor that drain the water. There is no other door though. Instead, he finds a series of control panels and levers next to a large viewscreen. It's all currently off at the moment.
Milli
The pain from the cut dulls somewhat after a while. As he climbs down, something interesting happens. Mell finds gaining footholds and handholds easier. Rather, his grip on the metal is stronger. Even if he's not clutching anything, just making skin contact seems enough to make a secure connection. He makes faster work of the climbing, and soon finds himself at the bottom of the tower. There is a relatively small building forming the base, and empty streets leading towards the light of his goal.
