I just realized that the yellow people on the map are actually Yelb, not Herenthor. That is kind of embarrassing. I could continue on the current track of interaction with the Herenthor if they so wish, or I could take back the encounter. I'll wait until Joegreenbean is able to say whether he is in favor of this or otherwise before I make another post. Sorry about that, I'll make sure that my color-detection abilities are up to the task next time.
