A demonic cult recently performed a ritual to great success, part of its leader's grander schemes. Her work near Nerosyan complete for now, she left a token force to guard the site, no longer needing it, and prepared to travel elsewhere for grander plans. This activity, though, has been noticed. The ritual site was supposed to be completely abandoned, but a group of traveling merchants noticed the strange activity. This was reported to the Nerosyan leadership, who in turn have pressured Venture-Captain Jorsal of Lauterbury to get involved. Jorsal has decided to send the PCs, to investigate the site itself, assuming that a place so near the city likely isn't much of a threat.
