You should be able to fabricate claims anywhere you've got a landborder or a shared seazone unless it's the capital of a merchant republic.Did a game as Nubia. I've noticed that I cannot expand into the Sahel because in my path there is a province which is Sunni (I can't holy-war it), and it is ruled by a burgher so I cannot fabricate a claim on it. Is there any way this can be addressed in some way?
(Edit) And some more:
Ultimogentire is available to unreformed pagans.
Committed a change to the beta branch that should hopefully fix Ultimogeniture.
Nope.OK. What about the pagan with Primogeniture? Any idea?
