Kardak the Mystic (One Shot)

All John Cardy ever wanted was to be recognized for his talents at magic tricks and sleight of hand. He's talented, but not enough to get noticed for it until he comes across a (unbeknownst to him) cursed ruby. This ruby grants John the power of invisibility. As Kardak the Mystic, he performs feats no one else can with this magic. Unfortunately for him, going invisible isn't just a trick of the eyes, but rather entering another realm parallel to our own. And something inside that realm wants to use Kardak to enter our world for dark purposes.
