THERE ARE NO ENTITIES ON LEVEL ZERO: An Essay.
There are no entities on level zero. (Yes, I know it is class 1 because technically there could be some half dullers around and if you're a new wanderer its deadly because of its emptiness so its a little dangerous, but thats the only reason. Also the MEOD may not always be right. 🤷🏼♂️) The reason people claim there are is because level zero causes such bad sensory depravation it causes paranoia and hallucinations. Any entities you see or perceive on level zero are most likely figments of your imagination. This is why documented cases of entity sightings in level 0 are rare. Most people who no-clip into level 0 have no resources on them and die from starvation/dehydration before they can be there long enough to experience these mental effects. The thing about level 0 is that there is basically nothing there. Nothing artificial, natural, supernatural, technological, or anomalous that can support any form or simulation of existence. This includes entities. Any entity that no-clipped into level 0 would most likely die/cease to exist after a while because there is basically nothing there. no matter how unusual or anamolous the needs of entities are, they generally need SOMETHING to sustain their existence. However, the nostalgic effect of level zero is something that some entities feed on, and can manifest some entities like wretches from how strong the negative effects of this are. However most people die on 0 before they could even go insane, let alone enter the wretched cycle. (This applies to animals as well, which is why you rarely see frontrooms animals in the backrooms at all. There is a theory that many animals may no-clip directly into level 81 which is why so many Frontrooms animals are seen there. However this could just be an anomalous effect of level 81, and the animals are generated there, although they would be oddly normal for being Backrooms-generated.)
Also, THE ISOLATION EFFECT. While there may be some entities immune to level 0's isolation effects, humans are not, and most entities probably are not either. It is also possible that some isolation effects (such as that of level 37) are powerful enough to effect everything. This may not be the case for level 0 however. The evidence for this is reports of hound or duller sightings by wanderers who first appeared and had never seen one before, or reports of actual attacks with physical wounds. (However there is a possibility that someone who had the resources to survive on level zero might stay there long enough to go insane and resort to self injury, dissociation, or psychosis. Although there would have to be an extreme case of dissociation or psychosis to create the illusion of an entity causing what was actually self harm. The survivor in question would have to already be mentally ill before entering level 0.) Usually these reports involve hounds or dullers, which suggest these entities may have the ability to cross through level 0's isolation field. However since frontrooms creatures cannot, it would be impossible to completely meet an entity and be entirely in the same dimension of level 0 as them. This means that they would be only partially no-clipped through the dimensions of level 0 making them less likely to cause harm. The most common entity type that has the power to no-clip through dimensions is dullers, (this is why they can no-clip through walls, ceilings, floors, or objects to attack,) although they may not be powerful enough to entirely overcome the isolation field, also possibly rendering them unable to fully manifest into the same dimension as another creature or manifest there for very long. This would explain a good percentage of reported entity sightings from level zero being of dullers or of something resembling a duller to at least some extent. So if you see an entity resembling a tall, skeletal humanoid to any extent on level zero you should avoid it at all costs, just in case. However any other type of entity perception, especially if it is vague or you're unclear of its reality, is most likely not directly real. What is real is the monotony and emptiness of level 0, which after long enough, can kill. The only way to survive is to no-clip to level 1. Hope you think of that or know to try and also master the skill to succeed, (hence "tutorial level" as this is as vital of a skill to Backrooms survival as running or hiding) or accidentally do if you ever end up in the Backrooms. Because if you hear something, it most likely HAS NOT heard you. You are alone.
THIS is the horror of level 0. So please stop spreading the myth that there are actually a bunch of hounds or something on level 0, or that lore followers are ruining it by adding stupid entities to level 0. This is not true. The official wikidot page lore and most other lore makes it very clear that few or no Entities exist on level 0. Probably. Or at least it should be that way. Stop trying to make up dumb lore that there are entities there, because that does ruin level 0. OTHER LEVELS EXIST. You can have deeper backrooms lore without ruining the psychological horror of level zero. THERE ARE NO ENTITIES ON LEVEL 0.
