The Demon Slayer Universe, 1820
You are Andy, a fresh Mizunoto recruit in the Demon Slayer Corps during the late Edo period. While the world ignores the shadows, you must balance grueling training and low wages against the rising threat of demons. Survival depends on sharp eyes and discretion in a society that criminalizes your blade and denies your enemy exists.
Accordia, 1007 ALB
In this universe, the species known as humans does not exist, has never existed in the past, does not exist in the present. This world is not Earth; the planet is called Accordia and consists of three major continents, each inhabited exclusively by magical races native to the Equestria at War and My Little Pony setting in 1007 ALB, which is set roughly around the time before the MLP Season 6 finale or the My Little Pony: The Movie (2017) era, possessing their own biology, cultures, histories, and political systems that fully replace any human analogues. The technological development of this world corresponds to the level of the 1920s–1930s, but all technologies, institutions, ideologies, and cultural phenomena are adapted to the magical nature of Accordia’s races and have no direct or indirect connection to human history.
Continent Equus - The Western continent, featuring nations such as Equestria, Olenia and the Changelings and others. The continent is well-developed in terms of technology.
Griffonia Continent - The Eastern Continent, with nations such as the Griffonian Empire, Wingbardy, Aquileia As well as the countries of the River Federation and others. The continent is well-developed in terms of technology.
Continent Zebrica - the continent to the south, Countries located on the continent include Hippogriffia, Chiropterra, the Realm of Kiria, and others. This continent is technologically less developed than the others. It is an analogy of Africa and Asia. The continent is home to various underdeveloped and primitive tribes, as well as well-developed nations.
The world of Accordia is a complex landscape of shifting alliances, industrial advancement, and ancient magic. Below is a summary of the key nations, races, and historical turning points.
I. Major Nations & Political Entities
Equestria: An ancient land of ponykind ruled by the Alicorn sisters, Celestia and Luna. It operates on the principles of Harmony but has faced internal stagnation and external threats.
The Crystal Empire: A northern kingdom of Crystal Ponies powered by the Crystal Heart. It was once enslaved by the tyrant Sombra and vanished for a thousand years before being restored under Princess Cadance.
The Changeling Queendom: Populated by insectoid shapeshifters who feed on love. Under Queen Chrysalis, the hives unified and launched a massive invasion of Equestria in 1002 ALB, which was narrowly repelled at Canterlot.
Stalliongrad: A breakaway communist state in the Severyana region. It was formed after a 991 ALB famine and a subsequent violent crackdown by the Equestrian Guard led to a successful revolution.
Nova Griffonia: Originally a colony of the Griffonian Empire settled by griffons, it became independent after the Empire's collapse in 978 ALB. It struggles with a weak industrial base and political instability.
Other Notable Lands:
Olenia: A kingdom of deer known for electrical manufacturing.
Yakyakistan: Home to the fierce and isolationist Yaks.
