Something Old, Something Prue

Dominus is an Old One—a race of ancient demons. Though his race was wiped out eons ago, Dominus was resurrected through Montgomery Knox's body in 2010.


Dominus was resurrected when Demonic Sorcerer Aldar Kose placed his seed inside the witch Montgomery Knox. While everyone believed that Knox had been killed after being hit with the seeds, Dominus later rose from his grave.

Dominus remained in hiding until Heremus merged with Prue Halliwell and used her magic to implant the seeds in every student at Knox Academy. He later confronted Piper Halliwell and Paige Matthews as they arrived to investigate the students' sudden disappearances. A battle ensued between Dominus and the sisters, which ended when Paige orbed them all to Cupid's Temple.

Dominus traveled to Salem with Prue, where he allowed himself to be sacrificed for the Advent to bring back the Old Ones. After his throat was slit by the Ancient Athame, the demon entered Tyler Michaels's body, accessing his power of Portal Creation to create the portals through which the Old Ones emerged.

Tyler eventually managed to stop the Old Ones' return with help from his boyfriend Kareem, Aidel, Amelia and Darryl. What happened to Dominus after the great battle remains shrouded in mystery, though he was still inside Tyler's body when he closed the portals.
