Lodgers in Grim Night

The Lodgers decide to spend Halloween in the AUU, which celebrates their own version known as Grim Night, spending it on it's origin world of Wraemontir. It is a world that, even after it's long-inhabited periods, remains nine-tenths unexplored and uninhabited, with the population limited to a relatively small area along the edge of one of the three main continents, a zone of uplands and river plains bordered on one side by the unsealed ocean and on the other by vast expanses of desert known as the Heaven Vale. By 3300 BC, it was more widely known as a grim birth place for witches and necromancers, though years of shunned reputations and executions for witchcraft have left them to be a hostile secluded populace of evil and suffering making them turn to dark magic, alchemy, and the powers of the occult, and their millennia-long goal of AUU conquest after millennia of prejudice, creating an artificial hell called the Penance Realm, which was designed to induce emotional trauma and sympathy to it's creators, among other creations like biotic-like devices, monstrous steeds and guardians, and a variety of other feared creations, going by the name of the Grimsisters and lesser-known warlock variants, the Grimbrothers. They marked their territory with terrible spirits and horrid hallucinations that send them into an unconscious near-death experience. Though the Grimsisters are infamous, the world eventually grew a Teadr 3 society which shrugged them off as myth and only praised them with Grim Night. Though other horrible figures are remembered such as the powerful and sadistic necromancer known as Wraemon the Desecrator which the world itself is named after by his Grimsister worshippers, and the renowned Öurounreich (AUU Frankenstein), among a hundred others. Though this world is still famous for the most intense celebrations of Grim Night as it's birth place. But when a dark and nihilist Grimsister named Queen Phobius X comes and throws many of the heroes into the Penance Realm, the remaining ones must not only stop Phobius, but help the existing Grim Night icons establish peace, and show that the Grims are not as bad as they were, and that there was a misunderstood method to their madness involving the magic they use.
