Amora Underwood fell unto a spell her mother put on her to protect from evil forces that would give her powers for evil. She transferred her in a box, sending it through a portal to a place where she knew her daughter would be safe. Her book of spells is inside the box along with her valuables except for her necklace that holds the key to her destiny. Amora's mother, Cyerra, fought off her captors to ensure her daughter's safety. As the portal is closing, she threw the necklace before her enemies took her away. Ten centuries later, a young man sneaking into a museum to steal artifacts comes across the crate, not knowing his world will clash with hers.
