Ruslan, Baril, and Lou:
The door swings open very easily, nearly banging against the stone wall from Lou's pull. Inside, you see bodies. Various bodies of different shapes, sizes...and stages of decay. In fact the smell reaches you just as your eyes take in the hallway. It goes on for another thirty feet, bodies of humans, humanoids, and animals littered throughout and making the stone floor impossible to see before there is another door.
Along the walls, there is dried, brown coloured splotches of blood and clawmarks of various shapes and sizes. But the door on the opposite end is clean and pristine...wooden, but with four vertical, metal bars along its surface. From this distance, you can't make out any handle on it.
Toryn, Pabsit, and Oskar:
There aren't any hidden drawers that you can find within the desk, and Pabsit's examination of the tiny lines tells him that more of the lines go to the stairs than anywhere else...though the desk area is still very populated with them.
And in the silence, you all hear a noise. Above you. Not walking...but moving. Sliding almost, but not even that really fits. Grating, maybe? Or scratching...but single, and moving from one end of the ceiling to the next. However, you cannot see anything directly above you, so either you're imagining things, or the source of the sound is up on the next level.
