This is so sad and so true. We don't know anything about Fissoa, 90% of the realm has no real opinion of anything in the East... it's very parochial, else why would we have a tradition of depositions? There is a lot of self loathing in PeL.
Insular realms usually don't go making wild threats to their far-off neighbours about forcing a religion upon them and having them abandon their claims to half their land.
