Level 72 is the 73rd level of the Backrooms Lore.
Level 72 using computer generated images.
No environmental threats are at play. All land is stable, with no natural disasters. Most, if not all substances are safe to ingest or drink. You are the entities. A small amount of ambient noise is present. This amount of Noise is about equivalent to what would be present in a majority of The Frontrooms. A small amount of natural light is present. This is about equivalent to the lighting in The Frontrooms at night. Wanderers will not be able to see well at this level of lighting, but most creatures that have good nocturnal vision can see just fine. There are no abnormal mental threats in the level.
Description
Level 72 is a very dark place with many crimson-colored plants covering its walls. Eating the plants will most likely kill you, because when the plants detect acid, they produce a chemical compound named ortho-diethynylbenzene dianion that is IMMENSELY powerful. The pH scale goes up to around 14 and then it transfers to the pKb scale where the smaller the number, the more powerful. A one that isn't even 1 can cause severe chemical burns very fast. The normal bases end around -2 before super bases come into play. A -2 pKb base with dissolve glass, metal and skin very fast and will also turn water and blood into vapor near instantly. After you have that, you have the superbases, which the weakest one is estimated to be around 100 trillion times more powerful than a -2 pKb base, which is -22 pKb. The pKb scale ends at -31 at where the base at that level will catch on fire if it is exposed to air. At this point, the bases are nothing compared to the chemical produced by the plants. After the pKb scale, you have absolute proton affinity where the higher the number means a stronger base. The weakest of these bases has 1747 kJ mol-1 and the strongest is the one produced by the plants, which is ortho-diethynylbenzene dianion. Ortho-diethynylbenzene dianion has 1843 kJ mol-1. It can rip protons off even some of the most stable molecules so ingesting it will definitely kill you, no matter how strong you are. Now lets get into the interesting stuff, not rambling about bases.
The corridors of this level are very confusing with the tiles changing directions and the plants moving... very confusing. Candles that get replaced and go out appear very often and can light your way. Going very deep into the level, you may see a room labeled "Staff Only". Inside the room, you reach a unrealistically big room with seemingly endless monitors viewing people walking across the level. On an eye-level monitor is a choice. "Would you like to be an entity for a day? Yes or No." If you choose no, or walk out, or break the monitor, or do anything other than choose yes, then all exits to any other level will be blocked. If you choose yes, then for a day (Frontrooms time) you will be an entity that has one goal: replace every candle that has gone out. The entity you are is you, but is invisible to everyone else. You also can now see candles you need to light near you through walls and you now have a fanny pack that carries presumably infinite candles. After a day of lighting candles, you can be let out of the level and can be let out of the level. However, you have to light about 700 or so candles in the day that you are awake. Not the exact number is known and if you do not like the required number of candles, all entrances to other levels disappear.
