Warptorch

This magic item looks exactly like a burned-down torch, and may be found in a wall-bracket in one of the warp passages of the castle. When lit, the Warptorch casts light just like a normal torch, but it is not consumed by the fire. Someone carrying the Warptorch can see all the possible exits from a variable warp point or passage in the Castle, and may choose which one to leave by.
