The Backroom Colonists, previously known as The Backroom Pioneers, was originally an exploration group that ultimately united with a collection diverse factions and smaller groups under an elected minister. They are a powerful and well-known organization within the Backrooms, thriving in hundreds of levels. Unlike the M.E.G, the prime directive of The Backroom Colonists is to simply provide a place to call home for those who are lost, a place of survival under the harsh purgatory behind the codes that make up reality. They have a much looser, non-governmental approach to things.
The Anti-Entity Agency (A.E.A.) was a group consisting of around 120 people of unknown identity; they referred to themselves the Anti-Entity Agency and believed that they could destroy the creatures lurking within the Backrooms forever. They dressed as business men and sold supplies such as radios, steel, and rare items such as almond water. The group was founded around 1950, and dissolved in 1988. It is unknown where the members went after the group dissolved, but some theorize that they were raided by the U.B.A.
The Anti-Entity Group (A.E.G.)
The Anti-Entity Group (A.E.G.) is a modern subgroup of the Anti-Entity Agency, created with similar goals after the former's dissolution. Similar to the A.E.A., the group actively hunts and kills entities in the Backrooms. The group has a total of 212 members, and holds a moderate amount of supplies, including Almond Water and a large armory of weapons. Their members are very highly trained, with most being proficient at hand-to-hand combat and weapon handling. The A.E.G. has remained largely controversial with their notorious kill-on-sight policy for entities, hunting down all anomalous non-humans, dangerous or not.
The Brutus Experimentation Organization is a group dedicated to studying entities within the Backrooms. This group is responsible for experimenting on entities in various levels; they are most well-known for their experiments on Counter Entities. They also give supplies to survivors, but it is rumored that it is only to gain a better reputation amongst wanderers. The B.E.O. was founded in Level 11 after an agreement was made by 3 people, one of their names being Brutus, and the identity of the others remaining unknown. There is not much known about the group itself aside from its frequent experimentation on entities.
"No longer do the people of the Backrooms have to live in consternation of the unknown."
The Entity Research Committee, or the ERC, is a Backrooms group created to research entities within the Backrooms. It is allied with the M.E.G. and is responsible for the discovery and documentation of numerous entities. They have various outposts stationed across levels of the Backrooms. They are friendly and are heavily armed.
The United Backrooms Authority is a secretive group hiding in obscure levels undocumented by the collective database. This group tends to invade smaller groups and gain power through raids. Furthermore, the United Backrooms Authority are expert trackers and can navigate through levels other groups cannot. There are theories that this group is currently hiding in the shadows of level 6.
The Backrooms Red Cross is a medical/neutral group within the Backrooms trying to help any wanderer in need. They try to bring a free health caring system to the Backrooms itself. The history of the Red Cross dates back to somewhere in the early stages of Backrooms exploration or teleportation incidents, leading up to a massive development of a Red Cross group within the Backrooms. In the years leading up to the foundation of the Red Cross, in the Backrooms, they helped wanderers in need and tried to get as many people as possible out.
The Entity Recycling Association (The E.R.A.) is a highly secretive trade organization consisting of a small group of unknown members. The group is thought to sell goods crafted from parts of hunted entities. The E.R.A. does not divulge any information regarding their practices, though it is rumored that they work in conjunction with the A.E.G. to receive a majority of their supply. It is thought that the group performs secure trades with high-profile groups and individuals. The rarer the entity is, or the more dangerous it is to hunt, the higher the buyers are willing to pay. The locations at which they operate are as of yet unknown, but it has been advised not to interfere should one come across a trade-in-action, as there have been reports of eyewitnesses going missing.
They Who Seek, also known as "The Seekers" or "TWS", is a cultist group that worships an Empyrean named “He Who Sees”. The group was founded in the mid-1900s in which the followers sought to He Who Sees, AKA "The Seer" or "HWS", for immortality and any other things that they were promised by him, thus their name. The main goal of TWS is to convert and/or sacrifice enough people (preferably those who pose a threat) to HWS until he regains his former might. In the meantime, the other goal is to put a halt in the operations of other groups in the Backrooms as well, especially the M.E.G., so that they're weak enough to neutralize with ease when the time comes.
The Royal Court is a collection of godlike beings, said to have assisted The Divine One in governing The Backrooms as a kingdom in an age immemorial. The court eventually fractured as the result of treachery from within, initiating a series of events that led to The Backrooms becoming what it is today. Although it was initially believed to be a myth, evidence now suggests it may be more than that. In fact, it seems that the court is currently reforming, due in part to the efforts of The Keymaster, who believes that their unity will be necessary to combat new threats.
