Level 1000

'Now that you're done with Cluster I, are you ready to make the dangerous journey to the levels of Cluster II? I bet you're prepared...'

By the way, Level 1000 is the 1001st level of the Backrooms and the 1st level of Cluster II.

Description
Level 1000 appears to be series of random hallways. The carpet is blue, the wall is white or tan concrete, and there is a light bulb hanging from the ceiling. This level contains a lot of old furniture, such as a sofa, table, ceiling fan, closet, and bed. When the wooden door is found, it normally leads to an empty room with some useful supplies. There is also a computer in this level, but it is uncommon.

A report stated that many pipes and wirelines were discovered on the wall and ceiling. The majority of the liquid in the pipes is almond water, there may be cloud water in the pipes, but this is rare. Some wanderers attempted to break the ceiling and discovered numerous pipes and wires. It's unclear what these pipes and wires are capable of. According to one theory, Level 1000 provides a source of electricity and liquids for Cluster 2. If you walk far enough, you will come across a boiler machine, be cautious of this machine because it has the potential to break and produce an explosion.

As you progress through this level. Power outages will become more frequent, the carpet will become very damp, the wall will crack or break, and more beings will appear, therefore it is best not to travel too deep in this level.

Some wanderers claim that they noclipped in the Frontrooms and ended up in Level 1000 instead of Level 0. It's unknown why.

White Rooms
Level 1000 also has a section known as "White Rooms." u/Minimegaman090 discovered this section. This section's structure is identical to that of the main section, but the area appears larger and the structure is made of white metal. The majority of the areas in this section will feature windows with the other side being a white abyss. Because the windows in this section are unable of breaking, it is unknown what happens if you go through them.

It is not advisable to spend too much time in this section. It has the potential to cause rapid loss of sanity and death. The strangest effect in this sector is that when you enter it, your vision will become black and white. If you leave this section, this effect will be removed.

In this section, no entities have been reported.

Note found in Level 1000
 "This place... it's white walls, a white ceiling, and blue carpet. It smells of mildew, and the floor is slightly damp.

I got here when I was sucked into Level 999 by a Void Barnacle, and managed to resist the whispers. I think this is it...

I've found another human. His name is Hiro and he noclipped directly here after falling down a hotel laundry chute. He wasn't aware of levels below, so Level 1000 seems to be a different noclip location isolated from the first 1000 levels."
