Level 456 is the 457th level in the Backrooms.
Description
Level 456 appears to be a sewer underground, though strangely the ground is made out of the dirt. Along the way, the walls have terrifying pictures of white tall humanoid people with blood around their faces and bodies. These are called Thrashers and are exclusive in this level Some are smaller, some have black clothing, and some even have limbs. These pictures seem to be a warning to explorers that there are these dangerous entities that look like this on the level. This may be correct due to the fact very similar entities are present at this level. The entire level reeks of dried blood, as it is littered on the walls, floor, and ceiling. Through the level, you may hear vicious roars and groans in pain. Though it is unclear where these sounds are coming from. The closer you are to a Thrasher, the louder they are.

Thrasher Survival Guide
If you ever hear the roaring get louder, run in the opposite direction as you are near one of these vicious and monstrous creatures. Thrashers are insanely fast so if one spot you, you are most likely not going to make it. These zombie-like entities are theorized to be previous humans but this is unconfirmed. Thrashers don't have a great hearing so just try to not be too loud.
Colonies and Outposts
No colonies or outposts are on this level.
Entrances and Exits
Entrances: To enter, find a door in Level 455 that says "The sweets End Here" to get to this level, or drown in Level 34 to be taken here as well.
Exits: To exit, crawl through a small square hole in one of the walls to be taken to Level 457. Finding a hole in the floor to be taken to Level Hole. No-clipping into a Thrasher will take you to Level DARK. Though this is not recommended.
