"Once you're all up there, I'm moving her a bit off from the Tower," Covis says, "I heard that once the whole building exploded, sinking the keelboat that was waiting for the scavengers to return."
Ghuntomas gives the rope a tug, and it holds. He starts the slow ascend towards the window. As he's barely gotten on the wall, the rusty piece of railing that the hook attached to breaks off, the piece dropping to the waters and the climber ending up on his hind.
Another throw, this time more accurate, sends the grappling hook inside the window. Without another incident, everybody manages to scale the wall. A single blood rook circles around as the group is climbing, though as nobody is approaching the roof, it doesn't show any aggression.
The arrow slits didn't yield much information as not much light passed through them and there was no source of light inside.
At last everybody is in the same place. The room you entered is a large semi-circle, probably occupying half of this floor. There isn't much in this room, though marks here and there show that there has been something here before: scraps of cloth remaining of wall hangings ripped down, and even some of the floor stones have been dug out of their place. There is also a monstrous form the size of a cat, though judging from its pose and not moving, it is merely a corpse (Damien recognizes it as a monstrous breed of centipedes).
The room only contains one wooden door in the middle of the straight wall ahead of you. The door looks somewhat bloated due to the damp air, but it doesn't look like it's stuck.
