In the realm of the Boiling Isles, where magic and mystery intertwined, a once-innocuous experiment gave rise to unforeseen consequences that would forever alter the fate of its inhabitants. One day, Amity Blight accidentally fell into a puddle of Duplication Goo, which connected to oceans and lakes of it, filling the entire Boiling Isles with Amity Blight Clones with 50% thinking they're the real Amity Blight, and the other half knowing they're clones.

And Luz, unable to watch the Amitys argue over who gets to be with Luz, goes into the goo on purpose. This led to chaos across the Boiling Isles, especially when you throw in the DNA and traits of Amity and Luz's friends and family. The DNA of Eda, Lilith, Hooty, King, Willow, Emira and Edric and Boscha were inserted into the clones. At first, Odalia wanted nothing to do with it, but she inserted her and Alador's DNA's into the goo, but they also inherited Amity's good natured soul, so the Amitys with Odalia's DNA Traits recieved the best of Odalia's traits without receiving the worst traits.

Unfortunately, there was an army of Amity clones, led by the Leading Amity Clone, wanted to rule the Isles for themselves. The Leading Amity Clone rallied a legion of like-minded Amitys, and together, they schemed to claim the Boiling Isles as their own, fueled by resentment and envy.

The battle that ensued was a clash of ideals, a confrontation between darkness and light. Amidst swirling magic and fierce determination, the Leading Amity Clone's army of Amitys faced off against the united front of Luz and Amity clones led by the originals themselves. Sparks of magic illuminated the sky, echoing the intensity of their emotions.

In the end, it was the unbreakable bond between Luz and Amity and all of their friends and doubles – the original souls that had sparked the very adventure – that proved to be the catalyst for victory. Fueled by the depth of their connection and a shared understanding, Luz and Amity's army prevailed against the odds. The Leading Amity Clone's malevolence was quelled, and her clones were freed from the twisted influence that had consumed them.

With the conflict resolved, the Boiling Isles began the arduous process of healing. The duplication goo, tainted by the echoes of discord, was carefully contained and eventually transported into separate realms – the Luz Realm and the Amity Realm. These realms would become homes to the countless clones, where they could forge new lives and embrace their individuality in harmony in their own realms.

However, one day, their worlds will collide, and they will meet, leading to something pretty interesting.
