Description[]
Level 301 is a strange place that one rules as weird. At first glance, it looks like an old, abandoned museum; left to fall apart but still obsessively organized. But underneath, it's a carefully designed ritual space where everything must be in groups of thirteen, and nothing is random.
The air feels heavy here; stale, cold, tinged with the scent of old paper, wax, and a metallic hint, like dried blood. Footsteps bounce loudly through the tall, arched hallways, and the silence feels deliberate, almost forced. The museum is oddly bright with chandeliers holding 13 flickering bulbs, but shadows linger in corners; thick, slow-moving, watching everything.
When one steps inside, they are greeted by a spacious central atrium. It's round, with 13 hallways branching out, each leading to a small museum. In the middle, there's a large guide rose carved into the marble floor, its 13 points marked with mysterious symbols that shift and don't match any known language. A sign hangs above, swinging gently without any breeze, engraved with the phrase:
“Observe, Repeat, Remember. Thirteen sees all.”
Each hallway leads to a different type of gallery; books, weapons, timepieces, and more, totaling 13. They're all exactly 130 meters long, though perceptions can stretch or shrink that measure. At the end, there's a sealed double door with a brass number 13 and a mysterious sigil that shifts subtly with each visit, as if it senses being watched.
Each gallery has 13 rooms, each filled with 13 objects of the same kind, perfectly arranged. The furniture—like display tables, glass cases, and pedestals—is handcrafted, aged, and labeled with plaques. But the plaques are pretty vague; many read simply:
"Object 7 of 13. Untitled. Unknown Origin."
Some galleries feel like frozen moments in time. The Painting Gallery, for instance, displays canvases from all eras, but they all seem strangely alike; portraits where the eyes look straight at you, glassy and unnerving. Some paintings have been seen blinking, and others whisper softly as you walk by. In the Book Gallery, dusty, thick tomes write and rewrite themselves, lines shifting and disappearing in real time. One visitor reportedly lost their mind trying to read all 13 versions of a book called "The Thirteenth Hour."
But there’s something deeply wrong with the architecture.
The longer one stays in the museum, the more strange things they notice: doors that weren’t there before, staircases that just end in ceilings, walls that seem to pulse like they’re breathing. One will never see all 13 museums in one visit. Trying to do so will mess with the layout; paths loop back on themselves, leading one to rooms they’ve already seen or into replicas that subtly change, like objects replaced by wax versions of one's own body.
Some exhibits seem to respond to attention. Staring at the Weapons Gallery too long might make the blades twitch, vibrate, or inch closer to the edge of their cases. Meanwhile, the Mirror Gallery feels almost alive; some mirrors show reflections of the room 13 seconds into the future, while others reflect nothing at all, even with someone standing right in front of them.
The museum staff even shows up in thirteens. Rarely, one will see 13 mannequins dressed in old-fashioned curator uniforms lined up at the end of a hallway. When one gets near, they disappear. Sometimes, though, they reappear faintly in mirrors, slowly turning their heads to stare right at them.
This museum isn’t about preservation; it’s a ritual carved in stone. The exhibits aren’t just for looking; they’re meant to feed the number. Whether 13 is a god, a curse, or just a rule, nobody really knows. But one thing is certain:
You are not just a visitor here. You are part of the exhibit.[1]
Museum Structure[]
The Museum of Thirteenfold has 13 sections, each a small museum focused on a specific type of object. These sections include:
Description[]
13 rooms, each lined with cold, silent figures. Every one has 13 versions; some almost identical, others distorting reality with eyes where mouths should be, arms multiplying or bending in impossible ways. A few look just like the wanderer, dressed exactly the same. Some seem to shift when you're not looking, and it's said that one set of all 13 disappears when no one is watching, only to reappear behind someone unexpectedly.
Description[]
13 halls of landscapes, desolates, and portraits. Each painting has 13 versions; some shift by lighting or details, others by entire scenes. A cozy cottage might turn into a burned ruin in another. Portraits blink, breathe, or change poses. Some viewers say they see themselves aged or dead in the frames. It's best not to linger in this wing too long; the paintings can start to blur with memory.
Description[]
13 rooms of dusty, warped bookshelves. Each shelf holds 13 books that look the same outside but vary inside; from playful poetry to detailed stories of the wanderer’s past. As you read, the words sometimes shift, changing their meaning and tone. One book is said to have predicted the wanderer’s exact moment of death. Some feel warm when touched, while others scream when opened.
Description[]
13 rooms filled with glass display cases. Each case has 13 weapons; swords, spears, guns, claws, and unknowns. They’re made of metal, bone, obsidian, or black crystal that glows. Touching one might cause hallucinations or rage. Rumor has it, some cause bleeding without wounds, and others make your reflection draw the weapon even if you haven't.
Description[]
13 interconnected mirrored corridors. Each room has 13 mirrors, reflecting not what is, but what shouldn't be. One might show a smiling version of you, another a room burning behind your back. Some reveal glimpses of your future seconds ahead, others show something watching you from behind your eyes. Breaking a mirror is said to bring its inhabitant into the real world, and some mirrors trap you once you look into them.
Description[]
13 sterile, humming rooms of impossible tech. Each display shows 13 devices; some look like phones or computers, others are strange, pulsing, or seem to breathe. Pressing buttons reveals familiar places, but twisted; like a livestream of your abandoned, moldy home or your own confused face staring back. Some machines loop eerie music or static voices that seem to whisper your secrets aloud.
Description[]
13 rooms containing 13 specimens each. Wolves with too many teeth, birds with human eyes, frogs twitching inside sealed jars. Some animals still breathe, others watch your movement with glassy eyes. One room has 13 headless horses, yet their hooves still reflect. Sometimes, a taxidermy piece is missing, and muffled footsteps sound behind the walls.
Description[]
13 rooms lined with mannequins dressed in 13 styles each. The clothes are a mix; robes, suits, battle gear, party dresses; but none quite fit. Some are bloodstained. Others smell like people you knew. A few mannequins twitch slightly between blinks. Wearing the clothes brings up memories that aren’t yours, and rarely, the mannequins move to take back what’s theirs.
Description[]
13 echoing chambers of ticking and silence. Each room contains 13 clocks, but none show the same time. One runs backward, another too fast, and one only ticks when you're not looking. Some seem frozen, yet get faint ticking when you get close. Staying in here too long causes confusion; people forget where or when they are, and some are said to have aged decades without noticing.
Description[]
13 rooms, each with 13 unique chairs, arranged in rings. Some chairs are elegant, others look grotesque. Some seem to invite you to sit, but those who do might see visions, experience sleep paralysis, or find it almost impossible to stand up again. One chair is always warm, another shifts on its own, and a particularly creepy one carved from bone seems to pulse faintly as you approach.
Description[]
13 rooms containing 13 collections of maps each. Maps, star charts, blueprints, and floor plans; all flawed. One map has 13 different layouts, none correct. Some lead to Level 0, others to “a place beneath all places.” They shift when you're not looking. One even maps your memories in ink, marking feelings at each spot. Burned maps respawn fully intact after minutes.
Description[]
Each of the 13 rooms contains 13 smooth, standing mirrors. Unlike the Mirror Hallways, these reflections feel alive. Looking into one might reveal your true self, your death, or your deepest fears. Some say their reflections stop copying them and start acting on their own. Avoid the 13th mirror, which shows a black void pulsing with your heartbeat.
Description[]
13 sealed rooms containing relics behind thick glass. Each set features 13 variants of a single artifact; like ceremonial daggers, cursed masks, or glowing crystals. They hum low-frequency sounds, and some respond to emotions. Staying too close for too long can cause nosebleeds, hallucinations, or mental breaks. One display has been known to change when lights flicker, swapping relics for items from your past.
Visual Documentation[]
Capturing visuals of Level 301 is notoriously unreliable and often misleading. Attempts to capture images or videos inside the level frequently result in the following phenomena:
Severe Distortion and Visual Corruption[]
Photographs and video recordings are almost always heavily blurred, corrupted with digital noise, chromatic aberrations, and ghosting artifacts. Many files become inaccessible or corrupted within minutes of being recorded, Even high-end Backrooms documentation equipment appears to fail or overheat without reason during usage in this level.
Invasive Manifestation of the Number 13[]
In nearly all visual recordings, the number 13 appears inexplicably and repeatedly replacing text on signs or exhibit plaques, superimposed across the footage like a watermark, sometimes appearing in the form of binary code, barcodes, or glyphs that translate to "13".
Attempts to edit or remove the number often cause the media file to delete itself or revert back to its original form with even more 13s layered over it.
Static 13 Phenomenon[]
In rare cases, both images and videos do not show any part of the museum at all. Instead, the resulting file is a static-filled screen with a bold, pulsing "13" centered on it. These files emit a faint audio tone when played, which has been described as "a low, pulsating hum" or "a reversed whisper counting slowly". Staring at these recordings for too long may induce vertigo, migraines, or mild hallucinations, according to field researchers.
Properties[]
Number 13 Influence[]
The museums most unsettling aspect is how the number 13 is everywhere. No matter what you look at or do, you'll keep seeing 13; whether it's 13 paintings, 13 stairs, or 13 chairs. The longer you're here, the more the number starts to mess with how you see reality.
Disorientation[]
Visitors often say they feel lost, wandering through hallways and rooms that seem to loop endlessly. No matter how far they go, the layout repeats, and the repeated number 13 adds a sense of déjà vu, making it hard to tell what’s real from what’s imagined.
Psychological Strain[]
The constant appearance of the number 13 and the dreading atmosphere start to wear on you. Over time, wanderers see hallucinations and feel paranoid, with 13 showing up everywhere. The place feels alive, like it's watching and judging anyone who enters.[2]
Environmental Hazards[]
Some items in the museum seem to have a malevolent side. Things like the weapons in the Weapon Museum or the animals in the Animal Museum can come to life if disturbed. Certain paintings might try to pull you in, and mirrors can trap your reflection, leaving you unable to move.
Entities[]
- The Collector: A mysterious figure roams the museum halls, known to collect rare objects and often leaving victims in 13 pieces. It's extremely dangerous; meeting it means risking your life. The Collector appears after something is disturbed for the 13th time.
- The Whispers: These invisible entities seem to follow wanderers through the museum, especially in rooms with books or mirrors. Their voices are faint but become louder and more erratic when visitors encounter objects related to the number 13.
- The 13th Wanderer: These entities are the spirits of those who have lingered too long in Level 301. They look like humanoid figures in tattered clothes, with faces marked by the number 13. They wander the halls endlessly, trying to lead others into the same eternal wandering or deceive them.
Entrances and Exits[]
Entrances:[]
- Level 301 can be accessed by entering a door marked with the number 13 on other levels, particularly those that involve museums or galleries.
- Occasionally, wandering into a room with 13 objects on any level may transport someone to Level 301, though it’s unclear how this happens.
Exits:[]
- Exiting Level 301 requires finding the 13th exit, hidden somewhere within the maze-like structure. Only one of the 13 exits will lead to a safe area, while the others will loop you back into the museum.
- Some wanderers have reported that simply closing a door marked with 13 leads them to other levels, but it’s not guaranteed.
- In rare cases, interacting with the 13th object in a museum will open a portal to another level, but these portals are often unstable and can take wanderers to unknown locations.
Notes[]
Footnotes
- ↑ "The paintings... they keep changing. I tried to leave, but no matter which door I go through, I find myself back in the same room. I’m starting to think this museum is alive, and it’s trying to make me a part of the exhibit." — A note found inside the Painting Museum.
- ↑ "I don't know what’s happening. I’ve counted 13 rooms and seen 13 doors, but it feels like I’m going in circles. The walls keep closing in, and I swear I hear something watching me... I need to find a way out before I see that number one more time." — A note found on a door in the Sculpture Museum.
