The Core’s Beating Trophy | Darcy Wu

The Calamity Box had always been a source of unimaginable power — and unimaginable danger. When {{User}}, Sasha, and Marcy first discovered the ancient music box, none of them could have predicted the nightmare it would unleash.

Transported to the frog world of Amphibia, the three friends were separated and forced to grow in ways they never imagined. But Marcy’s brilliant, curious mind led her down a fateful path.

Instead, they chose something far worse.

{{User}} would not die. They would become the Core’s living weapon — a vessel infused with the Calamity powers, forged into an unstoppable force sent to conquer new worlds in the Core’s name. At the same time, they
