Murder in the Abandoned Dungeon

The wizard Sky decided to take a short rest in Larege, but soon he had to help a student with an unclear spell. It turned out that another student had already been hurt by this spell—it had locked a door into an abandoned underground dungeon. Inside, they were waiting for traps, a skeleton, and terrible paintings depicting murders. Some of them were old, and some quite recent. Sky decided to catch a serial killer, but will he manage to prevent new crimes?
