Starting and staying as a North Germanic Asatru of any kind, take the Found Witch Coven Decision
Needs Northern Lords, and you must start AND stay North Germanic Ásatrú. The wiki build: in 867, replace the Chief of Gotland with a custom 34-year-old Norse Ásatrú ruler with six children plus the Diplomat and Witch traits. From day one, run Convert to Witchcraft schemes on your children - your HEIR must be among the converted, that's a hard requirement of the decision - and once three are witches, take the Found Witch Coven decision. The family that hexes together, stays together.
