Demon Realm

The Demon Realm is the homeworld of Eda, King, Amity Blight, Willow, Gus, Tibbles, Bosch, Warden Wrath, and Principal Bumpa. Despite it's name, it is a world of fantasy creatures including griffins, vampires, and so on (As well as giraffes, which were banished to Earth), as every myth made by humans were from this world leaking to Earth. As revealed in the SAFA series, the Boiling Isles, the setting of The Owl House, rests on the Lovecraftian world of Yuggoth, which has changed a noticeable lot since it's description in Lovecraftian lore, and that it was only adjacent to Pluto for a short time during Lovecraft's time. The realm itself was made by Azathoth, the ruler of Mischievers, to create monsters. But the inhabitants rebelled and broke off as their own world, and with help from Yuggoth's native race, the Mi-Go, banished them away forever thanks to the manufacture of Lovecraftium, an unstable metal that can harm Outer Gods. Luz Noceda currently resides here to become a witch, and currently fights against Azathoth's family and learns about the history of H.P. Lovecraft, who was a UUniversal Crusader who took the biggest risk of exploring what was outside dimensional space, the domain of Outer Gods.
