However, the Society's ally Lady Gloriana Morilla has secured a small group of Pathfinders a unique opportunity to study the museum's relics. All she needs in return is the Pathfinders' investigative skills to uncover the local earl's indiscretions—an earl who proudly identifies as Arnisant's direct descendant.
