* You yourself may believe in a different faith, heresy, or profess to only follow the Master's Church, but if discovered, you will be tried for heresy, the punishment for which can be as light as excommunication ( the inability to be apart of the Church ), or as serious as death.
You mean a lord of Lundland should not be openly affiliated with or believing in non-Lundish faiths or risk punishment? That's a bit of a problem in Almare's case, where the clansmen's religion has pushed aside the Lundish faith quite efficiently, and believing in their ancient gods is quite normal there, for lords and peasants alike. Perhaps uniquely in all of Lundland, I would definitely consider the Lundish church to be the minority here, as being practiced mostly by members of certain upper castes (old lineages of lesser nobles and knights who cling to the values of their forefathers (e.g. Owain Griffiths, the lord's brother, or Llyr Cardiff, Almare's ambassador in Jorvik)), and a few small converted communities.
So how does that work with the church? If they decide to excommunicate the lords of this realm, that seems reasonable enough to me, but I'd be unpleasantly surprised if they sent the inquisition to sentence the poor lord to death for heresy.
