Achadamey Of Magic

People randomly find these necklaces, or should I say, amulets. the amulet has a voice trapped inside, the voice can help people through their journeys of magic their necklace provides. but there's a catch. deep inside your head, something you won't remember doing, you choose if you will be good, or evil. Relationships with good and evil are against the law, but two people do it anyways.
