Suibhne's Quiz

Speak to Suibhne once per game day to take a quiz about the Corpselights in the Feretory and their mannequin counterparts. The true identities for each NPC vary for every player. However the Q&As never change for the player each time the player has to re-take the quiz. The quiz is a basic elimination game. Remember your correct responses, and or write them down in case the next question you answer is the wrong answer. You only need to get all 3 questions right to unlock Bee (MON).
