This is probably really easy to everyone but me. I'm in the crypt, with the crystal, in front of the elevator (or what I think is the elevator-maybe that's what's wrong). I've read here and other places "Use the crystal to call the elevator." How?

Turn just slightly to the left as you face the north wall (elevator). There should be a small indenture that when you point to it says "Receptacle". "USE" the crystal on it.

BTW, you'll be using similar receptacles later in the crypt with other crystals, so be on the lookout for them.
