Good call Sypher 
I believe it can split if it wants. I see no reason why it doesn't, if they are so angry about having Sevastian around. It's not like they had BR before Sevastian joined, or any of the regions commonly acknowledged as his domain.
It can not split. The last city of the realm is unable to leave the realm through secession though I don't know about changing allegiance. Also, I am not fighting for sides exactly or that iron willed is bad, what I don't like is that it is one-sided so I just don't like the situation in general. In any realm where the ruler is elected regularly, like Sevastion's, the exiled can always win the battle. Always. All you have to do is wait long enough and you win. That's what I don't like, that iron willed on the ruler's part does nothing, while iron-willed on the exile's part means he can't lose.
