Murder in the Abandoned Dungeon

Wizard Sky, staying in Larage to rest, takes on the task of helping a student with an unfamiliar spell. It turns out that another student has already been harmed by it, and the spell itself locks the door to an abandoned dungeon. However, instead of treasure in the catacombs, they are met with numerous traps, a skeleton, and a gallery filled with terrifying paintings depicting murders. Some portraits are centuries old, while others are quite fresh. Sky wants to catch the serial killer, but will he be able to prevent new victims in time?
