The Eidu Amulet was a mystical device used to transfer beings from the astral plane into a host body. In 2001, Spike got hold of the Eidu amulet before it was taken by force by the Eidu, minions of Yuki Makimura. Yuki hoped to resurrect The Master from the astral plane and bring him back to life in the body of Xander Harris. The Eidu amulet was placed on Xander's chest to awaken the Master. Unfortunately for Yuki, just as the Master entered the real world, he was killed once more by Dawn Summers using the vapor blade.
