Advanced Dungeons & Dragons Eye of the Beholder 2: The legend of Darkmoon

After the adventures of the first game, the heroes head to a local inn to rest and enjoy their newfound fame but a note gets slipped to them from Khelben "Blackstaff" Arunsun (Archmage of Waterdeep) who says that he sent a scout (Amber, a female elven thief/mage of neutral good alignment) to investigate reports of evil brewing in a temple known as Darkmoon but she has not returned. Khelben then transports the heroes to the temple to find Amber and continue the investigation, but it soon becomes apparent that not everything is as it seems....
