The first rule of the Backrooms is to never believe anything is truly real. Not until you can touch it, not until you can feel it. Even then, be on your guard around it, as it could become harmful in an instant.
We failed to follow that rule when it came to the sun.
Once a familiar, safe comfort to all, any sun within the Backrooms is now to be considered an immediate threat to all life. The light they provide is dangerous, their warmth is a tempting falsity. While the severity varies from place to place, there is a list of common signs that a being may be infected with Synthesial Reversal. The follow is a table provided by an unknown wanderer who sacrificed themselves to the infection in an attempt to log the symptoms:
Time Elapsed (Hours) | Symptoms |
---|---|
12-24 | Paranoia/Anxiety, Frantic Behaviour |
25 | Attachment to Light Sources |
26 | Aggression, Destructive Behaviourswhen removed from light sources.[1] |

While the remainder of the symptoms are left unreported, the conclusion can be drawn from this that this - whether it be considered a virus, the control of some external force, or otherwise, the infected host completely loses control of their body and mind, entering a state of complete delirium. As of the creation date of this document, 19465, it is unknown if an infected host is able to be saved. |

Furthermore, it is not recommended to attempt doing so unless you are certain of your methods. Should a loved one succumb to Synthesial Reversal, the kindest solution is to end their life. Do not join them. Do not follow them into the light. The you that once was will cease to be, and it will be agony the entire time the change occurs. TransmissionTransmission, as far as we know, can only occur between a being and the sunlight. It cannot be transmitted between other wanderers, and it cannot be transmitted from entities. Therefore, standing close to someone or something affected by Synthesial Reversal is safe for the most part.
PreventionPrevention, for the most part, is easy to do. The best suggestion is to simply stay out of any level with sunlight present. However we do understand that to get from one safe level to another, the trip may be required. If absolutely necessary, it is highly recommended to have the following:
Furthermore, when it comes to the sun, simply do not look at it. Do not approach it. Stay vigilant. Keep your eyes to the ground and navigate your way to your next exit as soon as possible. |

Transmission
Transmission, as far as we know, can only occur between a being and the sunlight. It cannot be transmitted between other wanderers, and it cannot be transmitted from entities. Therefore, standing close to someone or something affected by Synthesial Reversal is safe for the most part.
WARNING: AS OF 19465 THE FOLLOWING INFORMATION IS INCORRECT, PLEASE READ CASE 5 FOR MORE INFORMATION.
Prevention
Prevention, for the most part, is easy to do. The best suggestion is to simply stay out of any level with sunlight present. However we do understand that to get from one safe level to another, the trip may be required. If absolutely necessary, it is highly recommended to have the following:
- Complete coverage of the body through clothing. Dark clothes are recommended as they block out the light the easiest. Sunscreen has proven to be ineffective at this current time.
- Other blockout material to shade yourself. Umbrellas are highly recommended and it is suggested you layer them with other black material such as curtains and thick blankets.
Furthermore, when it comes to the sun, simply do not look at it. Do not approach it. Stay vigilant. Keep your eyes to the ground and navigate your way to your next exit as soon as possible.
AFFECTED LEVELS
As it currently stands, any level with either a day/night cycle or permanent sunlight is affected by this event, and will emit Synthesial Reversal as described. The following list, however, is a collection of levels where the side effects of the event have been more severe:
Level Affected | Details |
---|---|
Level 7 | While the level itself seems relatively unaffected, it would seem that its main predator has fallen to the sun. For further info, read Case 9. |
Level 10 | The crops have withered, and worms have become both carnivorous and cannibalistic. The classification of the level has been updated to Class 3 to reflect. Despite the low classification, residing on this level is not recommended due to the present sun. |
Level 23 | The Heart of Water is beginning to dry up. The plant material that makes up this level is deteriorating, mould and rot forming within the cracks and seams in its wake. On top of that, the beasts are becoming more and more erratic in behaviour, and the Buried Sentries are consistently activated. The classification of the level has been updated to Class 5, however concerns of its deterioration lead to beliefs that this will change to N/A in the future. Base Seedling shall monitor the level in the meantime. |
Level 29 | Hyperian as we once knew it is destroyed. Synthesial Reversal drew that aquatic monstrosity out of its depths, and the ensuing destruction took the entire island down with it. The classification of the level has been updated to Deadzone to reflect the event, and access to the island is a death sentence. |
Level 63 | The Level is completely untraversable. The constant sunlight has caused the grand vines that hold the bridges and platforms to start rotting away, causing collapses and destruction of safe zones at a rapid rate. The classification of the level has been updated to N/A, as in this state, the level simply no longer exists. |
Level 165 | In an opposite effect of what is often analysed for plant life, the plants of Level 165 have completely taken over the area and have become both sentient and hostile. The current running hypothesis is that the cause of this is the plant's main water source being Cashew Water. Not even the birds that reside here are the main threat anymore. In its current state, the level's classification has been updated to Class 4e. Further monitoring of the level is dangerous. |
Level 182 | The fungal species that inhabit the Fungal Sector have begun to spread and grow at an alarmingly rapid rate across the entire level. The blue and yellow mykitan mushrooms now permanently expel their dangerous spores, which have further evolved to begin to grow on any victim it takes. Those who have succumb to Synthesial Reversal in this level will find their bodies piloted not by the light, but by the mushrooms that feast on their body. In its current state, the level's classification has been updated to Class 3e. |
Level 240 | What has occurred here cannot be simply left as a log. Further info can be found in Case 4. I'msosorry… |
Level 247 | While this level is dangerous to inhabit to begin with, it seems a wanderer treading through this level set off the overdriven growth… and then it never reverted. It would seem the Gardeners have become consumed by the overgrowth and any buildings have been completely taken over by nature. In its current state, the level's classification has been updated to Class 3e. Were it not for the deadly side effects of the overgrowth, one could consider its mass coverage of the buildings a safe haven from the sun. |
Level 260 | When the event first started, many believed they would be safe in this level due to its constant nighttime state. Those who could stand the colder temperature moved into this level, almost making it the level with the highest wanderer count, and believed the Aurora Liminalis would keep them safe due to its innate healing property. For further information, refer to Case 2. |
Level 270 | One of the rare, and currently only cases where an entire level is reclassified as an entity. Read Case 6 for more information. |
Level 302 | The PE2 present here have become nigh unstoppable. They have grown to gargantuan sizes and have set the land ablaze. Outpost Aral, however, is still attempting to persist within the land without falling to Synthesial Reversal. The team currently sits at the entrance from Level 8, deploying the aid of PE10 to provide shelters and covers to hide from the sun. Currently, it is unknown if PE4 and PE7 still exist, we hesitate to simply state them as Extinct. |
Level 309 | The effects of the Rapture Spore have grown deadly and stronger, going as far to affect the Mycellennium. To enter this level is to enter a state of permanent delirium as you fall victim to Synthesial Reversal. The classification of this level has been updated to Class 4e to reflect, and it is not recommended to enter at this current time. |
Level 369 | Reports have described that the transformation that occurred to wanderers in Level 247 is now beginning to occur in this level. The level's classification has been updated to Class 3e to match. |
Level 414 | What has occurred to the Ivlania can only be described as a tragedy. It is unknown the fate of the Source and its people, but we can only assume the worst from what was gathered in Case 7. |
Level 422 | The Island Stalkers have become extinct, the event causing unforeseen illness within the entities. It would seem that other species within the level will soon join them, numbers reaching Endangered and Critically Endangered amounts where applicable and measurable. The classification of this level has been updated to Class 1e, and it is done so with a heavy heart in mourning the loss of such a biodiverse ecosystem. |
Level 544 | The riverbeds have dried and the forest is engulfed in ash and soot. 544-P's effects have grown severe due to Synthesial Reversal, and it is currently unsafe for anyone to enter the level, even when shaded from the light. The classification of this level has been updated to Class 5e. To enter here is to burn alive from the inside out. |
CURRENT SAFE LEVELS
The following is a list of areas currently considered safe to exist in. They are categorised based on the amount of darkness present and other factors that usually affect safety, such as entity presence.
Safety Level | List |
---|---|
Safest | Level 6 (Theoretically), Level 27, Level 46.1, Level 97, Level 128, Level 137, Level 146, Level 222, Level 250 (See Case 8 for more info), Level 345 (See Case 3 for more info), Level 688, Level 906 |
Safe If Careful | Level 37, Level 58, Level 79, Level 180, Level 224 |
Safe, but Still Risky | Level 45, Level 64, Level 218, Level 220 |
Safe for Now | Level 46, Level 186 |
