The Broken Golem

Adventurer, can you please h-help me? Minearm visited me a couple of days ago... You know, the magician with scary face? He gave me a high quality moonstone, but the potion backfired! I didn't mean to! I was terrified... He was so angry, and it's all my fault. Now I can hardly move, I think something's wrong with me. Listen, can't you hear that squeaking sound every time I open my mouth? I know I should return the moonstone, but I can barely move. Can you help me? Can you please bring 3 Perfect Moonstones Master Minearm? He knows a lot about the Dark Gem Stones. Maybe he'll tell you more. Please tell him I'm so sorry!
