The Three Architects

de:Drei Architekten
The Three Architects (also referred to as The Three Lights) are known as Guiding Light, Curious Light, and an Unnamed Red Light. These 'light' entities can be observed throughout DOORS in: The Lobby, The Backdoor, The Hotel, The Rooms, The Mines, The Castle and likely future floors.
== Guiding Light==
Guiding Light is the "main" light that assists players in The Hotel and The Mines by highlighting progressive items and locations and distributing death messages to players upon death. Guiding Light is only present in The Hotel, The Lobby (during the Tower Heroes Event only) and The Mines.
The Crucifix and Moonlight Candle are implied to be "powered" by Guiding Light. 
Guiding Light is represented by the "Moonlight' symbol that is seen in death messages screen after dying in The Hotel or The Mines, the "Spacetime" painting, the full trailer of The Mines, and Crucifix sigil; Guiding Light is implied as being "marked by [a] celestial". The "Moonlight" symbol can also be found on doors in rooms in the form of a barrier, where Figure resides, preventing it from leaving the room, and after the Seek chase sequence, closing the door behind the player, as well creating a barrier.

==Curious Light==
Curious Light is the second light who is between Guiding Light and the Red Light. Curious Light is mostly a neutral behaved light compared to Guiding Light, who helps indefinitely, and the Red Light, who appears to interfere with the players (from very small pieces of evidence). Curious Light only gives very vague information on sub-floor entities and does not highlight any items. Also, if a player dies to a certain entity too much (mainly Backdoor Entities), Curious Light will start to get more and more agitated as more times the player dies to them.
Curious Light emits sound and light similar to Guiding Light while the Red Light doesn't.
Curious Light's symbol seems to be the Starlight symbol, seen on its death message screen after dying in The Backdoor or The Rooms. on both versions of the "Spacetime" painting, and in the Vial/Bottle/Jug of Starlight.
Curious Light appears as one of the light candies in the 2024 Trick or Treat update. Eating its candy casts the effect "Volatile Starlight" which can either (over)heal the player or damage the player randomly, and will always give a short speed boost. This shows that this light is mostly neutral, sometimes helping the player and sometimes not.

== Unknown Red Light==
The Red Light is theorized to be focused on hindering players instead of helping as Guiding Light and, arguably, Curious Light are. It blocks The Rooms' entrance when Modifiers are enabled. The Red Light has not spoken to the player at all yet (except certain nudges, or the Tower Heroes event), but it is possible for communication in the near future (although the way it will try to communicate, like how Curious Light only appears in subfloors, or how Guiding Light is normally encountered, is completely unknown).
At the moment, The Red light doesn't emit any sound or a glow like Curious Light and Guiding Light do.
The Red Light's symbol is believed to be the Modifier symbol seen in the top right of the screen when they're enabled, which is also seen in the modified "Spacetime" painting. This implies that the Modifiers are, at least slightly, canon.
A possible reference to the Red light is that once the player dies in the hotel while modifiers are active, when Guiding Light would normally appear, the screen instead turns static-red for a few seconds, as if the Red light was preventing any Guiding Light communication reaching the Player. The red static can still be seen when killed in non-modified runs for just a few moments prior to Guiding Light's or Curious Light's speeches.
The Red Light appears as one of the light candies in the 2024 Trick or Treat update. Eating its candy casts the effect "Can-die" which deals 100 damage (usually instantly killing players). This is a powerful indicator that the Red Light has malicious intent.
Even though the Tower Heroes Event is not canon, it is worth noting that this Red Light alerts you when enemies begin flooding into The Library. This may hint at the idea that it assists the Figure in some way.

==Trivia== 
*The title "The Three Architects" is derived from the encrypted message seen on the Crucifix's banishing sigil when it is used against an entity: "OneOfTheThreeArchitectsMarkedByCelestialsAssistsYou". 
**The Three Architects being "Marked By Celestials" seems to imply that the symbols for all of the Architects are meant to resemble celestial bodies, which clearly lines up with Guiding Light's moon and Curious Light's star. It's not entirely clear what the Red Light's symbol is meant to be, but it could resemble a spiral-like celestial body such as a black hole, nebula, or galaxy. Out of the three, it's more likely to be a black hole, seeing as the symbol would only resemble spiral galaxies, which are just one of many types of galaxies. There's also the fact that all discovered spiral galaxies have a supermassive black hole at the center of them such as our own galaxy, the Milky Way.
*The Three Architects are the three primary colors.
**This is the RYB color model, which applies to paint and pigments. The RGB color model applies to light, which is ironic given the Architects' association with light.
*During the Library cutscene, Guiding Light breaks the lamp to distract Figure. This is easily noticeable due to Guiding Light's sparkles nearby the lamp after the cutscene finishes. 
**Guiding Light also closes and holds the door at the end of the Seek chase sequence and the Library to protect the player.
**It also closes and holds the door at Door 151 (after the Nest), Figure's Room (110-114, 120-123, 160-184)
*The filenames for the icons of the Red Light and Guiding Light on the "Spacetime" painting are "scarylittlelight".
*In the Spacetime Painting, certain knob bonus milestones from Modifiers will change Guiding Light's icon and the Red Light's icon to different brightness levels and sizes. 
**The Red Light's icon gets brighter from higher knob bonuses, while Guiding Light's icon gets dimmer and smaller.
*While playing without modifiers, the “Spacetime” painting still has the Guiding Light’s and the Red Light, but they're extremely small (most likely to hide it with the other celestial assets in the painting).
*The Curious Light's block to The Backdoor for when the player doesn't have the "Detour" achievement represents its star symbol, although the Red Light's block to The Rooms when the player has Modifiers enabled doesn't have the Modifiers symbol.
**The Red Light's block is similar to the cracks in the walls of the Rift room and the Rift itself in The Electrical Room. They share a triangle particle that Curious Light's block lacks, but the Red Light's block uses the forcefield material like Curious Light's block does, instead of neon like the Rift cracks. 
***The sky of the Lobby and A-1000, Starlight, and both Guiding Light's and Curious Light's Rifts all use similar triangle particles.
*The generators in The Mines have their fuses glowing blue, yellow, and red. It is speculated that the fuses represent the Three Architects.
*The reason why the Red Light blocks off the gates to The Rooms is likely because the Rooms are incompatible with The Hotel modifiers.https://twitter.com/LightningSplash/status/1699830533578977640?t=fZ2Kc0jXAeSRSBb1K_QIag&s=19
**Also, in the tweet where Lsplash says this, he also says "also um.... l... lo... nevermind". This likely implies there was another reason too, probably something related to Red Light's intentions.
*Underneath the crucifix sigil and on the “entity door block barrier”, there is a moonlight symbol, referencing Guiding Light. Similarly, when the player escapes the Backdoor and the Rooms, they are teleported to the Hotel, and the door that took them there is suspended in the middle of the room. Underneath this door, they can see a starlight symbol, referencing Curious Light.
*The symbol of three chairs lined up next to each other at the entrance to the Rooms may be referencing the Three Architects who once resided there.
**It could also be possible the Three Architects are/used to be living beings.
*It is unknown if the Red Light will play a major role in the game outside of modifiers and the crucifix.
*The Three Architects have their own background color in the icons for DOORS, Guiding Light in the Hotel+ update, Curious Light in the Post-Hunt update, and The Red Light in the Modifiers update. This was hinting that the three light characters would be influenced in their own updates.
*A teaser on X by RediblesQW in March 2021, one of the first teasers ever of DOORS, showed a window in the Hotel, where three lights could be seen from the distance. They seem to have the same exact colors as the Three Architects.https://x.com/i/status/1372629719556972549
*The only friendly entity Guiding Light crucifies is Louie. It is unknown why they crucify them.
*Aliases for the Red Light made up by the community is Mischievous Light, Malevolent Light, Spiral Light, Blood Light, and Modifier Light. The most used alias is likely Mischievous Light. A less known alias is Trouble Light, because of its nature on causing problems to the Player one way or another. It being the third light in the generator further suggests this. (Because you would almost never see the light already placed on the generator.)
*A theory suggests that the Red Light could possibly be related to Hide and Haste.
*Since objects made by Guiding Light and Curious Light are named "Starlight" and "Moonlight", it is likely that Red Light's object could be named "Galaxylight" because of resembling a galaxy.
