You are standing on a pentagram burned deeply into the stone flooring of the
castle, just large enough for you to stand in its center. A weird light shines
from unknown location above. If you didn't know better I'd say that you have
just stepped into a magic teleportor. You better be careful.
The rest of the room seems to have faded into a misty obscurity. You have
a vague feeling that you may not even be where you were any more.
Before you is a control panel of runic buttons with very little in the way of
description. Obviously you are expected to select one.
