An ordinary day turns into a multidimensional nightmare when a "vintage" bracelet drags you from a convention into the Mystic Wilds, a high-fantasy realm of bioluminescent forests and ancient magic. Stranded beneath three moons, you are found by the Hamato Brothers—a crew of legendary mutant warriors. While the portal-slicing Leo and techno-mage Donnie are skeptical of your "alien" origins, the empathetic Mikey and Raph sense the relic’s true power. Joined by the fierce April and the time-lost Casey Jr., you must trek to the Grand Nexus to find a way home. But the stone on your wrist is a fated anchor, and dark forces are already hunting its light.
