Blood Moon Periods

**Blood Moons** are mysterious phenomena that can happen on any level in the Backrooms, though more frequently occur on specific levels. They cause a drastic spike in entity aggression and activity. However, for a Blood Moon to occur there must be some level of sight and sound present during the event. The exact cause of Blood Moons is unknown, and many of their properties are unknown; however it is theorized to be caused by level generation, more specifically, generation wipes Blood Moons often begin with the entire level reeking of blood before eventually seeming to transition into a Blackout Period, before eventually turning back on to reveal the lights changing color to a sickening Blood Red. These events are known to last days to weeks and don't occur for up to around 3 months after the initial event. Giving a period of general safety to users.

It is also not unheard of for Blood Moon Periods -- including other such phenomenon -- to happen at the same time as other periods, such as Blackouts, or even Blue Moons. However, these were often one-off events and the likelihood of them ever happening again is inconceivably low, as Blood Moons are rare themselves and the 3-month time frame is only an average, and one could appear at any time within a level. Though, Levels of *Blood*

*Moon Periods* marked in their Hazards / Anomalies tab, often have them more frequently than ones without it. If it isn't in the tab, you shouldn't worry about it at all.

When Blood Moons occur in outdoor levels, such as Level 10, they will often change the physical environment of the level, including the sky or any astronomical bodies such as moons or even the sun. However, in most cases, the sun will set in the level at a quickened pace before a physical blood moon rises on the horizon. Also during these periods, all supplies of water will seem to instantaneously turn into a mix of blood and other bodily tissues and liquids. The blood -- when tested -- seems to match the DNA or general blood type of the user next to it, depending on who sees it.

During Blood Moon periods, drastic spikes in entity activity and hostility are felt across the level. The entire level for the duration in which the event takes place will be regarded as entity-infested, and it will become impossible to not encounter an entity within the level. Any entity that was previously friendly -- regardless of what type of entity it is or how intelligent -- will become hostile towards humans. Entities with generally lower intelligence will also seem to gain some general sentience/sapience. Entities will also gain knowledge of users' locations across the level. Entities will seem to build up into a literal tide of entities until the period is over, killing anyone in their way, even other entities at times. Any source of light regardless of type, even handheld or hand will turn blood red, also including any lights emitted by entities such as Radio Crabs, or Lighthouses. Also during this period, drastic damage towards the level will be experienced, and depending on the category of the event, the damage will either be greater or less significant. Generally, it includes only structural damage to the level, though, structures made by humans and other entities have indeed been destroyed before. Once the period ends a loud noise equivalent to a gong will chime, and can be heard by everyone regardless of location, signaling the end of the period. All lights in the level will turn off and all damage experienced will be reverted once the lights turn back on, including all other entities.

## Blood Moon Variations

Blood Moons have three distinguishable types that can be grouped into four categories.

### Category A

Category A is the most common type of Blood Moon, they only last around a day at most and have a median amount of entities and activity across the level. This category is also called Mini-Blood Moons due to how generally tame they act when compared to regular Blood Moons. However, despite the name 'Mini-Blood Moon" these should still be taken seriously, as Blood Moons, regardless of type, are still excruciatingly hard to overcome both on your own and amongst other groups. During this period, a dangerous amount of damage to the level will be caused, including falling debris, broken glass from the lights, collapsing ceilings, collapsing floors, et cetera. The stench of the period will be noticeable, however, not enough to be significant. Generally, finding a high enough area in the level, or a safe area to hide will let you pass by this event quickly. Once you've found your safe spot -- preferably with a weapon -- do not leave that area under any circumstances. It is simply not worth it to leave your area. Either leaving the level through Pitfalls or No-clipping is the best course of action to survive a Blood Moon. However, if that option is not available to you and you must stay, hide in generally dark areas of the level or up on high areas, most entities are incapable of climbing or even noticing you on top of incredibly tall or high structures. Secluded rooms would also work, such as ones with large unopenable doors, or even locked doors in general, as entities aren't likely to group up on one person. However, if you happen to be within a community, follow instructions on what to do and simply wait it out. All communities within the MEG are required under the *Stanford Act* are required to be prepared and adequately equipped to deal with both possible entity and environmental threats and citizen needs.

Entities in this category range, but the majority are common entities that are either friendly and now turned hostile, or previously hostile and present within the Level. The amount of entities is around 7 to 1 for every person.

### Category B

Category B is more commonly associated with 'real' Blood Moon events. These events are often inhospitable for people outside of groups, as they last around 3 - 5 days at best and cause gross damage to the environment. Entities within the level are often of rarer variety and even more violent than Category A entities. Your best hope for surviving one of these is to seek shelter within a group. Groups will often want to remain hidden from other entities within the level and will usually turn off all lights as a measure of defense. However, will still accept anyone coming in as a person seeking asylum. Entities will appear in large groups, sometimes filling hallways with their numbers, making it impossible to escape them once you've encountered them. They will often instead just be filled with more dangerous entities such as Blighthouses or Signal Bears. Sometimes, unique entities such as Prince appear during this period. Entities much like him will often attract other similarly rare and powerful entities, and they will often form large packs of entities that hunt down wanderers across the level. Information about these is generally very scares

### Category C

Category C, known as "Shrieker Events" are extreme versions of Blood Moon events. Past this category, these events are usually unsurvivable without the odds being in your favor, such as being adequately supplied or prepared beforehand. Shriekers can be detected way beforehand by simple changes in the level, usually a few days or hours before the event. Such aspects are either quite obvious or very benign. For example: if the carpet or flooring within the level is soaked in some kind of liquid, be it helpful or harmful, it will instantly be transformed into blood. If the level rains, it will turn into blood, and so on. The most obvious signs are spontaneous earthquakes or low rumbling noises. Once a Category C is in effect, it will stay in effect for possibly an indefinite time. This type of event gets its name from the loud ear-piercing shriek that signifies the beginning of the event, which replaces the toll of the bells that commonly start most events. Instead of just happening instantly across the entire level, this category will emit from the center of the level and move outwards in all directions in a large wave. Anything caught in this wave will be killed instantly. However it is survivable, by getting to a high enough elevation within the Level, you can narrowly dodge the wave. However, it doesn't get any better after the initial wave, as more may emerge, carrying a large number of entities after the waves have subsided. The amount of entities is around 50 for every one person in the level.

For a long time after this event, the level will be completely inhospitable. The wiki page for the level will be updated to reflect this fact and will change once the level has been declared safe. These events are the rarest when it comes to regular events, only being observed a few times on some notoriously dangerous levels such as Level 8.

### Category D

Category D are hypothetical events, that have only ever been recorded once on a level with some modicum of proof to back them. They are regarded as the rarest type of Blood-Moon event and spark the complete and utter destruction; or rearrangement of a level. This event was recorded on the former Level 018. The level used to be a moderately level 0-esque level, filled with barren rooms resembling something like the manila rooms. The level may have been the Manila rooms at one point. A blood moon event was caused within the level by unknown means, but for some reason, persons on the level experiencing the event were suffocated to death by the increasingly abhorrent smell of blood. This most likely is a worse version of Category C's blood air. After communications were gone from surviving members of the base on Level 018, the level then began to violently shake and convulse until eventually became completely destabilized, but not destroyed.

What is left of the former Level 018, is now the aberrant level My Dearly Fragmented.

## How to survive these events

While it generally depends on which type you are facing, and some can be unsurvivable for this reason, they all generally follow the same rules and aspects that give them a modicum of predictability. Exploiting this can keep you alive during these widely feared events. First a disclaimer, this is not a completely soundproof, foolproof method and it can fail on occasion and entirely depending on the category you are facing. Take this with a grain of salt and if you are in a Blood Moon Event, regardless of type, you should leave the level immediately.

First and foremost is the elephant in the room, How to survive the waves. The first thing you should do every single time regardless of type is find an elevated area. Waves are not exclusive to Category C, they are just more noticeable and fatal than others. Be very weary when you are on the ground floor of any level during these events. On average the waves only reach a large height of around 475 - 670 centimeters (15.5 - 22 ft) so any heightened wall or surface should keep you well protected. Once you have reached your heightened position, make sure to keep it and stay there no matter what. Get comfy as you may be there for hours to even up to a week at worst.

## Footnotes

1. ↑ In a period of around 48 to 72 hours, the level will periodically have a large surge of invisible energy across the level. This acts sort of like sonar, however instead of reflecting specific targets, this reflects imperfections in the generation of the level. Although occasionally this may break and cause further deviations in the level as well as imperfections.
2. ↑ Signed in 1999 after the destruction of MEG Outpost: Stanford. It was signed by the Impersarios as well as other leading members of other groups such as Async, the BNTG, Docuventers et cetera.
3. ↑ Often, Category B types are caused by Prince appearing within the level.
4. ↑ Any water that is found naturally within the level (including almond water) will be turned into blood essentially.
5. ↑ These waves occur on every single floor of a level (if present)
6. ↑ The average for when these periods start and then end is around 2-4 weeks at best.
7. ↑ If the event does not end after a day, you are guaranteed to stay there for at least a week.
