EarthPlanet EarthThe World, or Earth-U662312 (the "U" standing for universe) is an expansive planet that features a wide variety of people, cultures, and ecosystems. It is the main setting of countless media, including most roleplays. Earth contains many native species, with the dominant, sentient species being humans. It is also an abandoned Gem colony.

Earth is a vast planet that includes plains, mountains, oceans, and deserts. The planet is divided into seven continents surrounded by vast oceans. The planet is orbited by a single moon.

While not usually mentioned, the Earth in The PvZ Institute is actually the same one from In a Locked Room. In the Institute RP, events like Quadmageddon are referenced and the Locked Room Gang (usually Jelo) have made cameos, while in the IaLR RP the Institute was even shown in an Easter special. While this may not be true despite evidence and mentioning, this still is a bit of lore that some roleplayers, like RodimusPrimeHans-Cuff210 and JeloElducal widely accept.
