Per discussion here, when Norman resurrects from his death, he will immediately reach out to Elias, confessing to what he did under the Fog's influence as the Goblin and seeking his forgiveness for being so ... monstrous. Once Elias has reassured him that he was, indeed, under the Fog's control and that All Is Well in terms of his follower status, Norman will share his idea:

With Elias' help (and other Fourthies TBD), he wants to establish a facility where he can try to engineer chemical cures/medicines to curb the hunger or lessen the pain or severity of transformations and weaknesses to things like sunlight or water. I've saved up Mana coins for him to buy the building space necessary, but I would really love to give you the opportunity to use this as a plot seed if it works at all with anything you've got planned for Elias!
