Gosh, you spend a couple days not really paying attention and suddenly everyone's out for your blood... what's this, now, about killing/purging the Exiles? I'd like to note that never, at any point, has Oran or the Orange Clan done any aggressive or hurtful action to anyone in Nesse, and arguably we did a recent service to the city by removing those Exile clans who have. Before anyone gets to invading just yet, why don't we actually start some diplomacy, hmm?
EDIT: and actually, the term "Exile" doesn't really apply anymore. Or at least, not to the Orange Clan (and probably Moon Shadow too); we have not been a part of Nesse for a couple hundred years, and Oran has existed as a working entity for three generations or so. Try "Oranites", or "Orana", or even "Oraquis". And really, there is a new crop of perfectly good exiles that might want to use the term now, so why don't we let them have it?
