I realized that "Cleaved" does not make that much sense when watching other Disney shows. One question that I have is what is the realm of magic supposed to be? It was implied to be connected to every world, yet destroying the magic only had an effect on the version of reality that Star versus the Forces of Evil takes place in. On the Boiling Isles there is magic so whatever happened in "Cleaved" could not have been multiversal. Also confusing is that Meteora stayed a baby after the magic was erased from Mewni, if her infancy was magic based then how did she remain a baby? Implications are that her powers and not magic were what made Meteora a baby again.
