Hey Jack, I have to wonder: did Victor visit the labyrinth, or is knowledge of what a Pthumerian is something common (at least to a hunter)? Correct me if my understanding of the lore is wrong, but I would imagine that the average Yharnamite has no idea about Pthumeru or possibly the labyrinth in general - and by that token I would also think that Adelicia would not be familiar with them? On the flipside I could see her knowing about the significance of bells in matters of the arcane.
