If you mindread one of the idiots in the upper roon you'll find out that he threw the key out of the window and it's on the beach underneath eagles nest.

The upper room in eagle's nest has three levers by the far wall that disable all the barriers in that area.

Note: i'm a warrior & i also summon a demon to fight beside me so i basicly have 2 warriors

I use the demon for melee and the creature for throwing range spells when he's not busy peeing on everything.

It is a side quest (not pertinent to main quest) but you can find the Book of the Dead through the top teleporter in the old cave.
