Ow God I am happy about your enthusiasm. I am just going back home today so I will be able to answer and post in full detail later.
Later I will post a draft map with the territory claims and a genealogic map that I think will be useful for everyone. I will try to clarify any open aspect as well.

Honestly, I love the idea of the IC funeral situation, so we will do that. I have to anounce a few NPC which will kind of represent a small neutral fraction remnants of Muin's nobles, captains, courtisans and bureucrats. 

In any case most of these passed away aristocracy has dissolved into each of your clans, and only few remain as mere administrators of Muin's keep. Just wait a little longer and we take off with this NRP.
