@RimewindPhoenix If she said "I quit" and left I'm not sure if she could still be an adventurer, at least not with the same name. She carries the noble family's name and their backing. Would another guild be able to shield her from the consequences? I don't think the Silver Rabbit of the Night Sky could, they depend a lot from their backers. And the hero's party was the strongest group until Orin was kicked out, whoever is backing that group might be on par with that status or even be more influential. Orin was able to leave because it was the hero's decision to kick him out and like the noble said they don't care about him. It was probably this group that suggested to throw Orin out, it doesn't seem that the hero is that capable of thinking for himself.
