A question.
House Ærthegn, if one paints them as 'classical' Ærthegn "Wrækan Dreor" by canon seem to be both a Renegade Knight house, and a Imperial aligned one.
Would I find rules for this house someplace, if Im tempted to get and paint a knight as a old style House Ærthegn? Or do they count as something else for rules as imperial allies?
