Saetha's Wedding

The Lodgers and Heroes Act return to the world of Mewni to attend the wedding of Saetha and Anewas, hosted and protected by Star and Marco and their families and friends, and while the wedding goes smoothly, a new monster comes in the form of Chaemera, a deformed monstrosity feared by even other monsters and created by Globgor from stolen magic from Eclipsa and biological remains of all the monster races exterminated during Mewnipendence Day as a weapon meant to scare Mewmans away for good before meeting Eclipsa, who was released by a very overeager Junjie, and thus with the groom and bride captured by this abomination born from the ancient sins of Mewmans and while it starts turning people in Mewni and beyond into monsters, the Lodgers and Heroes Act have to put a stop to this.
