"The cherubs’ live in the universe the kids’ session will eventually create so we know they complete sburb in the future." I thought they lived on the earth that the beta kids left, but way in the distant future, like how the exiles live on the destroyed planets after the sburb players enter the medium. Because I dont see why the universe created by the kids would include an earth. No hate, just trying to understand this.

The exiles lived on pre-scratch Earth long after the kids had entered the Medium. Post-scratch Earth is the one covered in water. The kids will bring post-scratch Earth into the new universe since Vriska has captchalogued Earth and given it to John then suggested that they live on it in the future. Also the room where the cherubs live is on the meteor that the trolls and Dave and Rose traveled on which has landed on Earth.
