Earthrealm

Earthrealm is one of the many dimensions known in Jeice's AU.

Taking place thirty after the Final Splatfest (Chaos vs Order), Earthrealm experiences an invasion of mysterious monsters from an unknown place on Earth, leading Inkopolis and a group of new members of the Inkopolis residents to fight back and protect the world from their rampage, and whoever is making them appear.

Due to the gods of Earthrealm wishing to make a larger and better world for the mortals they watch over, the planet is 1/3 bigger than the original Earth, and allowed for an otherworldly object to crash into the Earth, where it still lay dormant.
