You knocked on the tombstones in the graveyard as Derot ordered, causing an ancient ghost to appear. You killed the ghost and recovered the Charmed Cube from its body. However, you could not open the cube and were forced to ask Munin for help. He promised to open it if you killed a few Sparkles for him. You did as Munin asked. As promised, he opened the cube, which was full of precious treasures. Derot, not wishing to anger Ulgorn, decided to report the treasure to the boss.
