Don't Nobles normally not have any authority in the adventurer's guild in these stories? You can clearly see the Noble goad them into joining her if they want the restrictions lifted, that 100% shows she's lying about whatever to have them put limitation on the group.
Well, hopefully she gets taught a lesson, would be nice if Goblins raped her too. But, well, we can't have good endings like that in these stories.
Thanks for the TL
