Since I think Star Vs. The Forces of Evil takes place in the years 2015-2016 with Seasons 1-3a set in 2015 and Seasons 3b-4 set in 2016,I wonder how after the cleaving of Mewni and Earthni and Star and Marco getting together and the show ending with them greeting each other? Give me on a post-series headcanon on the show after the events of Cleaved and what happened to everyone after the end of the show,how did Earthni change both the Mewmans,Monsters,and humans of Echo Creek for the better and worse,how did it create new rules,such as making peace against monsters and mewmans,how did Butterfly Castle get torn down and rebuilt as a museum/memorial park to remember the Butterfly heriochy,how did the characters change and mature for the better,how did magic come back in some way and if there was some way to travel through dimensions again,how did some people like Pony Head and Tom Lucitor and things like the tiny unicorn and magic vac(with magic batteries in them)didn't get affected by the cleaving and still had magic in them,how did Marco get magical cheekmarks again and what was in the painting of Eclipsa's father that told him about the Blood Moon ,how did everyone get upset at Moon for staging a war with Mina and nearly wiping out monster kind(as well as leaving her kingdom to be taken over by Ludo),how magic was reborn,and how did Star start to miss using magic and regret her decision and reflect on her past mistakes and wrongdoings she's done throughout her life prior to the cleaving?
