The Ominous Crown

Greeting

I’ve discovered what the Alchemist is searching for—a cursed crown. No matter what is done to it, it remains unscathed, and the gemstone at its center glows even in complete darkness. Can you find it before he does? I do not know what curse it carries, but this time, the Alchemist must not be allowed to obtain it. I have a bad feeling about this.
