I dunno how thoroughly you've read the boards so far, but in a nutshell: the party was friends of this guy Edvers Kells, this sort of larger-than-life adventurer/homesteader guy, who got accused of stealing a prized artifact called the Iron Sphere of Sthombo and was executed for it. While they were attending his burial the party got ambushed by this cult called the Six-Pronged Crown and started investigating what happened. They fled Sthombo looking for Edvers' daughter Zora, had some wacky misadventures, and found her in this massive subterranean complex known as the Badgerways which she was trying to use as a way to sneak into the city of Hazard undetected. She informs the party that Edvers really did steal the Sphere, but that the Six-Pronged Crown forced him to somehow, and before he was captured and executed he gave Zora a coded message and told her to take it to her mother in Hazard. Right now the party is in a crypt under the city, trying to find a way up and out.
