Hriston
Dungeon Master of Middle-earth (He/him)
I haven’t read the adventure, but it seems clear to me from what I’ve read here in this thread that the NPC is an Easter egg included to be recognized by fans of the novels in which she appears. To the OP, I would say that your experience is the module working as intended. Your character most likely recognizes the NPC by name because she’s an infamous personage of the FR.
