The tomb was an African construction, from the same place Mʔ was forged, during the Primordium Age. It had the form of a pyramid, with an entrance to a lower, subterranean section, and several pillars and urns inside. For millennia, one of the Guardians waited in the temple for the next Slayer to use the Mʔ.
By the year of 2003, the woman had became the last Guardian, and the tomb placed in a cemetery in Sunnydale. Buffy Summers found the tomb, where she met the Last Guardian and learned their history.
Although, during the encounter, Caleb had invaded the place and killed the Last Guardian, ensuing a duel against Buffy. During the fight, Angel arrived and assisted Buffy, to step out and watch her finally defeat Caleb, cutting him in half with the Scythe. Buffy and Angel kissed, and he gave her the Amulet. Unknown to them, the First Evil and Spike watched the entire exchange from the shadows.
