Hmmm... I'm not sure exactly where you are, but I think you're in the area Wyv is talking about. CAn you find the spot on
Bsftcs' maps? I know it's not specifically marked, but it can help to identify just where you are.
I thought the problem with the kitchen elevator involved being stuck at the top, with the elevator refusing to go down. If you're below the elevator, you *should* be able to jump into the shaft and exit through the opening on the bottom. I don't remember if there's a wall or door there that gets opened when you activate the elevator; if there is, you're indeed toast (barring the casting of vanish, teleport, or the mystical reverse time spell).
I don't think that Call of Home will work; seems to me that works outdoors only. If you are really stuck, you can click on revert game, which will take you back to the last town you exited. Sometimes you can lose a lot of gaming that way, but it may be better than starting over...
Let us know if that covers it or not.
