[spoiler]who was the guy in the room?

[Swarms]

I didn't finished the game yet but in the begining when we are in the tunnels with spiders the first ones wich haves a ladder that u need to bring back. I mean who actualy was the guy who got killed by something in the upper room(he's that guy that cotted off hes thongue). I still haven't found out who he was... i'm on the chase part! and i can't pass it cuz my graphic card sux and things get all laggy so its very hard (i have a Nvidia Geforce 6200 TurboCache...i know it sux!!)Guess i can only continue penumbra with a new graphic card...I just wanted to know whos that guy.

I don't know about the guy but another question could be that: What was the thing that draged that guy in that hole?

Spoiler below!

'Cause it doesn't sound a Spider, and Dogs don't go into that sort of holes or even make them, and it wasn't that Rock Worm 'cause the hole is much more smaller than the Worm...

Spoiler below!

You see worms in different sizes, maybe a worm who fitted that hole exists?
