Most everyone here is going to try to sway you to join their realm on BT; everywhere always needs more nobles. I am part of Fronen and IVF, though soon to be Melhed and IVF. Heavy fighting will be found everywhere except Nothoi, who seems to just chill in their regions.
I suggest that rather than ask the players where you should join, go to the wiki and read about each realm, their government, etc.
