[spoiler]who was the guy in the room?

[Thaliur]

MAny spiders might be large enough to move a human body.
He could also have been killed (also could have been killed? Sounds better, but it's been a long time since I had English in school) by a yet not encountered species of giant ants

[edit]
I just thought I should clarify that by "Many spiders" I meant "Many spiders working together", not "Many types of spiders"
