Gothi and the Priesthood of Gorum
All of the holds around Feyjasfjord belong to former vikings, and they all primarily revere Gorum, the god of battle. Each farm's master is also the gotha (plural "gothi"), the main priest of Gorum. He has Knowledge (religion) and knows how to lead the various rites, but mostly they aren't actual clerics – they tend to be fighters, warriors, or barbarians. If the farm is held by a woman, then of course she is the gotha. Gull-Skeggi is the local gotha; he is quite lax about the rites unless there's an actual battle on. Gorum probably doesn't mind.
