That queen is just as guilty for allowing shit to continue without putting a stop to it. It angers me, that she will not face any repercussions for her inaction.
The goblin guy can probably take out the entire official military force of that country on his own.
Idk what you want the queen, who's effectively a hostage to do?
Turn to the church? As far as she knows they could be all in on it + all the ones in her country are probably controlled by bishop goblin anyways.
Turn to the otherworlders? They are all going through bishop goblin as well, before they end up controlled as well.
Everyone who thinks that it's easy to stand up against overwhelming evil, when you are weak yourself, has never been under true duress.
