My son marries a Tarth girl, they have a daughter. She grows up and decides to join forces with Granny Irane. A couple of years later, my other son who married a Pariden girl, has a son who comes of age and stays with me. Can he marry his cousin, since she resides with the Tarth? Or say he was a son from the first couple, can he marry his sister? Also on a different note (and not so deranged), why does everyone hate Altar? It doesn't matter where in the faction power tree they are, every one is always asking me to go to war with Altar.
