ES AU: Cloudy, with a Chance of Thunder

(Yes, the description is bad, I'm sorry qwq)
Jolteon, Flareon, Vaporeon and Shiny Sylveon have lived their entire lives in Greenhill forest. While both Flareon and Vaporeon had pretty shelterd childhoods, the same cannot be said for the other two who did everything in their power to provide for them.

Things however, weren't meant to last, as shortly after evolving the Sylveon mysteriously disappeared without a trace.

The story picks up two years later when unbeknownst to the three Eeveelutions one walk in the forest and the sudden reappearence of their brother would turn their world upside down.
Join them in their new day-to-day lives filled with drama, heart break and dark secrets, but also laughs, good times and maybe, just maybe... love?

(The story mainly follows the events of ES, with the addition of a Shiny Sylveon named Cloud, who sets in motion a chain of events that could reshape the multiverse as we know it.)

All feedback is appreciated as this is my first story, and I hope you enjoy reading. Thanks, and I wish you all the best!
