Description of level

Discovered in 2019, Level -1000 looks like a massive, well-kept garden filled with hundreds of different plants, some of which have never been seen before. There are some areas on the level -1000, such as a large cottage that many wanderers describe as "looking like something out of a fairytale". When you first arrive, you'll see a stone pathway with bushes and exotic-looking flowers on both the left and right. At the end of the pathway, you see the garden and the cottage. An entity known as "Mother Nature" resides in the house, and is hospitable and kind to wanderers. The facelings that live there often help Mother Nature take care of the garden and surrounding area, seemingly just because they enjoy doing so.

Entities that are exclusive to this level

Entity 333 is a tall woman with long, green hair that are actually thick vines with flowers and other plants weaved into it. She normally has green skin and green eyes, and usually wears a long, flowy dark green dress, however, she has also been seen wearing a white sundress, as well as other different styles of dresses. She has the ability to change her skin color between green and a normal human skin color, dark brown. This is because she can switch between relying on photosynthesis for energy and consuming food. She is the only one of her kind. 

Entity 8430 are carnivorous flowers with "mouths". The mouth-like structures are similar to pitcher plants and Venus flytraps in that insects are drawn to the plants by sweet-smelling nectar that covers the "uvula", and when the doomed bug is inside the trap, the mouth shuts close, and the bug is slowly digested by acid and symbiotic bacteria that also reside in the mouth. 

Entrances

How to get to Level -1000 is not fully understood. 

One wanderer (named Beatrice Rall) fell asleep in the Crimson Forest and woke up at level -1000. A group of 4 wanderers all no-clipped through a wall in level 2 at the same time, and all ended up at level -1000.  However, the most common ways to get to level -1000 seem to be no-clipping through the floor on level 46, level 32, level 5678, and by fully submerging yourself in water on level 37. 

Exits 

Exiting level -1000 is easy. Tell Mother Nature that you would like to leave, and she will send you to level 11 by doing a ritual. You need to lay down either on the grass or on a bed and close your eyes. Mother Nature will chant "Planum Undecim", which roughly translates from Latin to English as "plane eleven". Wanderers who have undergone the ritual have described the bodily sensation they felt while being sent back as being similar to how one feels while on anesthesia. You'll wake up not too far from an outpost or M.E.G base.

Bases/Outposts

M.E.G is currently trying to set up a small base or outpost to research entity 8430, more commonly known as Twolips.
