Wizard Sky, remaining in Larege to rest, undertakes to help a student with an unfamiliar spell. It turns out that another student has already suffered from him, and the spell itself locks the door to an abandoned dungeon. However, instead of a treasure in the catacombs, they are waiting for numerous traps, a skeleton and a gallery with creepy paintings depicting the murders. Some of the portraits are centuries old, some are very fresh. Sky wants to catch a serial killer, but will he have time to prevent more victims?
