OK, so I encountered the Wandering Monks for the second time and even though I know the correct answers, I accidentally selected the wrong answer for the number of ports and of course the monks attacked me. I was getting creamed (low on health, no potions, Gris incapacitated) but I was close to Kingsbridge so I ran back to town. I thought maybe the guards would step in, as they do with most aggro characters, but no, so I instead went into the Inn and rested for 6 hours. So here's the weirdness: when I came out, the Monks were still there and attacking BUT it restarted the dialogue and this time I chose the correct answer, got the reward from the Master Monk, BUT they were still attacking me anyway! I went BACK into the Inn and slept another 6 hours, and this time they were gone.
