Encounter Summary: The characters scour the Crab River shantytown for clues about the thieves of the Purple Sapphire and quickly run afoul with an up-and-coming crime lord and a priest of Dagon, both of which have interest in the gemstone.
One or more of the characters have contacts in the shantytown. Note that the bulleted information should be revealed through role-play, though a skill check raise should be required for each bullet past the first. Once the characters arrive in the shantytown there's a cumulative 20% chance per hour that Vendermark's spy and assassin, Priam, picks up their inquiries and their trail. At an opportune time (determined by the GM and gameplay) Priam and his thugs attack, as detailed in Disturbing Development, below.
