Cerebro
Cerebro is a system that was created for Professor Xavier back around the 1960's. Cerebro can track each and every Mutant in the world with the help of a telepathic mutant. If any other mutant were to use Cerebro, they could die. The only one capable of running Cerebro now is the Headmaster. The room is huge and shaped in a sphere with silver tiles all around it. Only with authorization from the Headmaster can anyone enter Cerebro.
