The Asgardian Pantheon, by contrast with the Southern one, maintains a single, separate High Priest for each of their major Gods, including among them Hoder, Odin, Thor, Loki and Heimdall.
High Priests are formally designated (or perhaps chosen by their patron Gods) and it has been hinted that they are unique for each god at any given time, and usually but not necessarily the most powerful clerics of their patrons.
Most if not all High Priests can invoke avatar proxies of their Patron Gods for manifestation during a Godsmoot.
