A reclusive widow is in over her head with supernatural forces. Discover the twisted secrets of the Margaster family and put an end to an evil threat before it overruns the city! The party's plans to steal some magic items from a rich noblewoman go awry when they find out she's made a horrible deal with a fiend to smuggle an army of Cambions into the city, bypassing Silverymoon's protective wards. Can the party stop her and defeat the fiends, or will they end up as a few more human sacrifices? This is as an expansion for Storm King's Thunder, but can easily be dropped into any campaign. Made for a party of 3-4 characters around levels 6 or 7. Content Warning! This adventure is pretty dark, and may not be suitable for all tables. The adventure's backstory involves a woman being driven mad by bearing fiendish children.
