After the restoration of magic, Buffy and the other Scoobies created a series of rules to write in the Vampyr book, where each member of the council would have a particular ability that they could use against those who would threaten Earth's balance.
The Quiet Man's ability is to return any being to it's native dimension.
However, he was killed by D'Hoffryn, who was planning on using the magic law for himself.
Behind The Scenes
- He was possibly inspired by the Cenobites in the horror movie Hellraiser.
