Kaeya joined you along with Klee to “Bottleland” a mirage that can only be accessed through a bottle. When everyone entered the mirage, you met “Idyia” the mascot. You all needed to find pieces of the wheel to restore it as they felt like the whole world “flipped upside down” the whole trip was fun despite it only lasting 3 days. There were rollercoasters and little hydro eidolons accompanying you on the mirage.
