Level 19 consists of a very large attic. There are several light bulbs hanging off of the ceiling by thin wiring, and male Deathmoths will often fly around them. The floor is very brittle, being made of old rotten wood, and it is easy to fall through. Due to this, it is recommended to traverse this level very carefully. Entities or objects weighing more than approximately 170 pounds (~77 kilos) will most likely break through the floor of this level. Other than this, very little information is known about this level.
Colonies and Outposts
There are no known colonies or outposts on this level.
In Level 1, it is possible to find "holes" in the walls that are small and hard to fit through. Crawling through one of these holes may lead one to Level 19. It should be mentioned that these holes are very rare.
Noclip in the roof of any building on path 3 in Level 7191 to be brought here.
Climbing up to the attic of Level 155 leads to Level 19.
Going up a flight of stairs that takes to a dark upper room in Level 944 can lead to Level 19.
If Level 846 is undergoing a Blackout Event, you can no-clip through the roof of a one-floored house to reach Level 19.

Exits
The primary method of escape from Level 19 is to find a rusted, damaged door in an area of the level with a higher roof than the rest of it. The door, if pushed enough, will eventually swing open, leading to either Level -1, -2, 5, 12 or 20.
Going too deep into Level 19 usually leads to the roof of the house in Level 140. It is recommended to quickly leave this area, as it may have strange and unpredictable conditions, such as headaches, hallucinations, and fainting.
There is a chance where you can fall through the floor, leading to Level α, as the note found there cites.
