On the topic of falling, is it guaranteed that someone who “slipped up” and fell wouldn’t be allowed to atone and resume/rejoin the guard? Hinjo even suggests this as a possibility for Miko when planning for her to be tried with the assumption that a guilty verdict is guaranteed, and the Aurzurites don’t seem to regard the goblins as having any protections under the law. So it seems plausible that they would give fallen paladins a chance to atone and consider their own ability to atone properly as a test of whether or not they should remain.
