Issei's Dxd Adventure: Into the Backrooms

Entity Types and Threat Levels

Hello Today I will be explaining the Entity types and Threat Levels. These entities may or may not be found in the backrooms, however they may or may not be seen, it depends on the person's view. 

Note: The entities and entity level is based on the Backrooms Fandom, not wikidot, since most of the entities here are not present in the wikidot and different numbers have been assigned to these entities. Not to mention this list has constant debating for the class level and the  number assigned to these entities, some of these entity threat levels are questionable even by me, honestly and the information taken is before July 8, 2022, so any changes after that is not considered.

The higher the entity level is, the higher their threat Level is, once the threat level reaches a certain level they cannot be killed or damaged by regular human weapons like Guns, Tanks, etc., but that does not mean that they are perfect beings, they can be killed by attacking a certain weak point or a certain location, it is not impossible to kill them, and yes their power increases the higher the threat level increases.

Entities's rarity is pretty variable, usually the higher the threat level goes, the more rarer they become, while this can also be reversed during a certain incident that may or may not take place in the backrooms, like a certain event that may result in the extinction or a thriving of a certain entity. Entities marked with the threat of extinction will have the EXNT next to their names

Here are the Classification of Entities, along with their threat rates and mortality rates, usually when in aggressive or provoked state.

Class 0: No threats posed whatsoever. Mortality and Threat rate less than 10%

Class 1: Not aggressive, but can cause injuries to wanderers. Mortality rate above 10 % and Threat Rate less than 20 %

Class 2: Not typically aggressive, but could be provoked into injuring or rarely killing wanderers. Mortality and Threat Rate above 20 % but less than 35 %

Class 3: Aggressive, but not notably dangerous. Mortality rate and Threat Rate less than 50 % but above 35 %

Class 4: Aggressive. (Typical classification level). Mortality and Threat Rate above 50 % but less than 65 %

Class 5: Dangerous. Mortality and Threat Rate above 65 % but less than 75 %

Class 6: Extremely dangerous. Mortality and Threat Rate above 75 % but less than 90 %

Class 7: Mythological. (Classification level for unknown/abnormal entities) Mortality and Threat Rate above 90 %

Here is a more detailed description of the entities that are present in Levels

Class 0: These are the most chill amongst everyone present in the backrooms, they are extremely friendly and won't do shit to you, even if you harm them, although don't do that. Don't be a Jerk to them. Examples are:

Mater Lunae (Entity 999): The only entity theorized to be capable of reaching a Class 7 danger scale, she is pretty compassionate who will not do anything even if you harm or insult her, but just show her some respect and compassion and you will have a person you can trust wholeheartedly. She is the goddess who resides in The Moon Level of the Backrooms, and will be seen roaming around once every 15 days. Despite this, she is capable of completely hypnotizing you once every 15 days, so just don't look at the moon.

Cat Pillows (Entity 13): A cat pillow at first appears to be a non-anomalous pillow possessing a faint odor of catnip. However, it possesses special properties. When a wanderer or entity places their head atop the cat pillow for a period of time exceeding 2 minutes, cats will pour into the room at a rate of one cat per minute. The cats will cease to enter the room if either the room cannot comfortably contain more cats or the subject removes their head from atop the pillow.
