Displacer Disk (Magic Disk)

Rary's favored mode of transportation throughout his fortress is a system of devices he calls displacer disks. Each disk resembles an intricate, circular pattern inlaid in a fine marble or tile floor, and is magically triggered by a code word known only to Rary and Robilar. The disks' code words can be changed at will by Rary alone. A single master disk controls all the others. An individual who knows the proper code words can be instantly teleported without error, either from the master disk to one of the other disks throughout the fortress, or from a lesser disk back to the master disk. Transport between the minor disks is not possible. Rary must first teleport back to the master disk in order to move to a different room. Each lesser disk has a different code word. A second, entirely different code word is required to teleport back to the master disk.
