The Golem's Mistake

Please stay with me!.. Listen to me!.. I beg you... *Cries*The Great Mage Mainarm came here. Great—and terrible—Mainarm... He gave me an excellent moonstone, and I made a foul potion from it. That's what happened! *Cries*I was so frightened... He became so furious that he forgot to cast a spell on me. It's all my fault... Now I can't even move—I used up nearly all my magical power. Something is wrong with me. Can you hear me creaking? I think I should return the stone to Master Mainarm. But where can I get it if I can't move? Please, find three Perfect Moonstones and give them to Master Mainarm on my behalf. He knows a great deal about dark diamonds and may help you find them. Thank you! Thank you!
