If all the force field in the sinister cavern is gone, means you already shut them down. There only 2 generator that need to be deal with.
If you are referring to locked chest which is near the generator that surrounded by a small pool of lava, the key for it is in another area. There is another area with the moving platforms on lava pool, right after you enter at the T intersection, it is on the alcoves in the wall. It can be easily spotted with the flaming bars.
The book of death is for Igor's quest. If you had the other guys as your necromancer, the book is basically useless.
