No never played one but my good party gets bad sometimes (XP does that to my guys, we just can't help it) and I, like you accidentally

wiped out the whole of the Radiant Heart. Just to let you know that you can also (accidentally once their quests are over) assasinate all the Morning Knights for good XP and no rep' loss. This accident occured during an interrupted thieving spree, I would have given the stuff back but noooooooo, they wanted to fight so it's their fault right.
