Oh lord. That proclamation is probably so much legal trouble. So, Mathilde has always been a dwarf. Is she a subject of Karaz Ankor, though? A case can be made both ways. And it's more complicated than Empire dwarves, as she is a thane and coucilor of a Karaz Ankor hold. Moreover, does it mean that Karaz Ankor has to recongise the Grey College as a proper guild? I mean, not recoginising it would make Mathilde obligated to declare a grudge on the spot.
This is a legal shitstorm.
And we propably won't see it until we return from the expidition.
