Crystal Library Card

Jealously guarded by the toughest Zugzwang Tower Mice, this beautiful card is actually a teleporter that will warp you inside Zugzwang's Crystal Library... so long as you are permitted to enter by the owner. Upon Zugzwang's disappearance, ownership of the Crystal Library has been passed down to the King of Gnawnia.
