From the depths of the cosmos descended a single stone, which started everything. When Twilight picked it up to study it, she didn't expect it to thrust her and her friends into different worlds. Being split up in the vast multiverse whose existence they've only discovered now, was already hard enough to handle. But they are now forced to fight against all odds and new enemies for the hope of getting back home.
Thankfully, some of them may receive the help of familiar faces.
