Level 482

"The Cavern System" is a sentient, anomalous level within the Backrooms.
==Description==
Level 482 is a sentient cavern approximately 200 meters underground. There is suspicion that Level 482 was the original location of an abandoned mineshaft from the 1800s located in The Frontrooms, but this is not proven. This level consists of multiple splitting pathways each with their own unique properties - some being rare than others. 
The level is classed as Undetermined due to the property of "shifting", a process the level takes that changes the size, shape and layout of the entirety of the cavern. Another key factor to note is the size also depends on the length and size of certain paths you take, some areas needing to be crawled through to access new areas -STRICTLY LIMITED FOR EXPEDITIONS OR RECONNAISANCE OF THE LEVEL.
Droplets of water trickling down from the roof of the cave have been determined as Liquid Pain, and it is advised to never drink from still water sources as it could have traces of the lethal liquid. Running water sources are presumably sources of Almond Water and are found safe to drink from to restore sanity and hydration. Caution is still advised as some sources may be a mixture of both liquids.
It is unclear when this picture was taken but a light source emitted from the image concludes a possible exit route of of The Cavern System. After an analysis, it was believed a cave entrance found within Level 91 was the exit point from this image.
Furthermore, to conclude this image, the researcher who took this image (Dr Tyler B. Green), has been found alive and well last seen conducting research within Level 94.
Multiple pages of research have been found about Level 482 and many theories have been created about the level. The only true pieces of evidence we have so far is (Dr Tyler B. Green's) research and an unidentified wanderer who presumably constantly enters the level to learn more about it.
==Threats Within The Level==
It is highly advised to read this information beforehand, to prepare for the dangers of The Cavern System. As there are many recorded non-entity hazards within The Cavern System the level could soon be changed to Class 5e:
Stalactites:
Stalactites are small clusters of immobile entities that look similar to regular stalactites. It is highly advised to be aware of your surroundings near clusters of these due to some of them hiding in the ground. Once stepped on, the Stalactites will proceed to impale whatever stood on them and most likely kill the victim or fatally injure them and the victim bleeds to death. 
The image captured above by researcher Professor Logan Brocklehurst shows an image of a cluster of Stalactites that had already taken the lives of many unfortunate victims.
Crawlers:
This next threat has caused arguments among M.E.G as this entity should make the level a Class 5 Level. These entities are known as Crawlers, and it is believed that an incident occurred in The Frontrooms, causing the Frontrooms version of the cave to collapse. These entities are found to be extremely hostile towards wanderers, and produce Liquid Pain as saliva. The Crawlers have the ability to camouflage as the surrounding rocks and stalactite clusters. A key point to make about Crawlers is the sounds they make; they produce a clicking sound from their constantly-chattering teeth.
Another non-entity hazard to avoid is the poisonous air as you venture deeper into The Cavern System. It is advised to carry a "Tanker" found within the level located wherever you noclip into the level from. "Tankers" are a modified, specialised Rebreather Tank originally used for underwater exploration to allow prevention of poisonous gas inhalation and death.
==Colonies & Outposts==
The lack of resources and unreliable conditions have prevented the establishment of colonies or outposts within this level.
==Entrances & Exits==
* Finding a Cave Entrance in Level 91 will noclip you to this level.
* Falling through a pool tile in Level 37 will have an uncommon chance to noclip you here.
* Attempting to kill any Deathmoths inside Level 5 will lead you to an area of The Cavern System surrounded by Stalactites or Crawlers where you will be left to die. 
 You can't escape this Level due to its nature; YOU CAN NOT ESCAPE US.
* There's an extremely rare chance of finding the Cave Exit to which you will be taken to Level 91.
* A dimly-lit hole found in one of the walls of The Cavern System has a rare chance to take you to Level 9.

 I can hear something crawling about the roof of this cavern. I'm uncertain to what the origin of the noise is but the clicking gets on my nerves and I swear I even saw a part of the cave MOVE INFRONT OF ME! WHAT THE HELL MAN! All I'm concerned about is my safety, and I don't feel safe when things start MOVING ABOUT WHILST I AM STARING AT IT. I'm not sure If I'm going to survive man! I can't even find my way about this damn place. Whatever happens next... my notes might become the last pieces of me. I'm hearing it again... I think I've got to get a move on...
Research Findings: Professor Logan Brocklehurst
 After spending my third successful day within this Cavern System, I've been able to determine a lot about Level 482. To begin, the sources of water are either Liquid Pain or Almond Water, but I was exploring an area earlier that might've contained a new, undiscovered liquid...whatever it was, it looked like regular Frontrooms water.
Continuing about my findings, there's a sub-species of Stalactite I've found and decided to call it a "Stalagmite". It's a Frontrooms reference to the regular stalagmites found in caves, but these ones seem exaggerated in both size and shape! They have the same properties as Stalactites but boy do they do a heck of a lot more damage! Poor ol' Tyler ain't seeing the light of day again.
My final finding however might just change the classification for this level. An entity I've seen on multiple occasions that have received the name "Crawlers" after the way they climb and walk among the level. Unfortunately, they're not as friendly as they look from afar as their hostility can easily lose you an arm or leg, or even your life!
The team will be leaving this level soon, so I better find all that I can before departure... let's get a move on!
INCIDENT REPORT: Professor Blake Adams & Dr Theodor Brown 
 Blake - Oh god! OH GOD!
Theodore - Calm down and tell me what happened to them.
Blake - It was horrifying. HORRIFYING I TELL YOU. IT... swiped them all, the entire cave turned corrupted and started collapsing...
Theodore - I. Wasn't expecting that... did you see anything out of the ordinary apart from the cave collapsing?
Blake - A figure.
Theodore - [Confused Look]
Blake - A figure. Tall, black. One giant glowing white eye... the cave surroundings hear him... corrupted and glitching all over the place!
Theodore - That's not possible. Entities like that don't exist. Unless you're talking about-
Blake - DON'T SAY HIS NAME. HE HEARS EVERYTHING. EVERY. LAST. WORD.
Theodore - Calm down Blake. You're going to be alright, you're safe with me. Please, tell me more about... what you saw around "him".
Blake - It was crazy and it almost seemed like he was decomposing the level! I... don't know what else to say.
Theodore - Let me speak with the Boss... he'll know what to do.
==Additional Information==
 The description that Professor Blake Adams gave about the event witnessed is the only one of its kind. The figure mentioned is still yet to be found, but recorded footage shows the effects of the figure on The Cavern System. It is unclear whether the effect still remains in an area of Level 482, but there is reason to believe it was moved when the level "shifted".
