**Item #**: SCP-8159
**Object Class**: __Euclid__ (Reclassification to __Keter__ is pending)
------
**Special Containment Procedures**:
**SCP-8159** is to be contained within a secure, bio-dome-style habitat located in **Site-19**, measuring 100m x 100m (or 328.08 ft x 328.08 ft).
The bio dome is meant to replicate a natural forest environment, complete with an artificial freshwater stream, native flora, vegetation, and gardening tools.
**SCP-8159** is to be provided 0.5 kg (1lb) of fresh meat daily, delivered directly into her containment area by **Level 2**-personnel.
In addition, she may be given fresh fruits or berries per request.
**SCP-8159** is known to often engage in casual conversation with personnel when food is brought to her.
**Note**: In the event that **SCP-8159** shows signs of agitation or distress, all food deliveries must be delivered to her via automated systems until her behavior stabilizes.
Personnel interacting with **SCP-8159** must undergo background checks to ensure they have no history of Illegal fishing and/or logging, Improper waste disposal, or Animal cruelty.
If they should meet these criteria, they may gain **SCP-8159**’s cooperation.
Regular audio surveillance is mandatory to monitor **SCP-8159**’s vocal activity.
Under no circumstances should any amplified audio or recording of her vocalizations leave her containment without **05** clearance.

**Description**:
**SCP-8159**, or “Nyssara”, as she prefers to be called, is a humanoid entity standing at approximately 208.28cm (6 '10'') in height.
She possesses light purple skin with a texture similar to that of velvet, along with digitigrade legs, giving her the ability to run faster than most humans.
She has four yellow eyes, with all of them capable of independent motion, and white medium-length hair, that remains perpetually unkempt.
**SCP-8159** possesses sharp teeth, with a bite force similar to a bear’s, at 1,200 lbs PSI.
Notably, she also has elongated bunny-like ears, capable of detecting ultrasonic frequencies, along with what appears to be a small tail resembling that of a scorpion’s tail.
However, the tail seems to have been severed at the stinger. The exact circumstances for this alteration is unknown, and **SCP-8159** has refused to elaborate on this.
Embedded in **SCP-8159**’s forehead, is a crescent-shaped metallic object.
**SCP-8159** claims that the pendant is a gift from an entity referred to as **“The Crescent Mother”**.
**SCP-8159** exhibits advanced hypnotic capabilities, and primarily uses this ability to lure in prey or incapacitate threats.
**SCP-8159**’s “sleep tone” can painlessly euthanize animals, however, **SCP-8159** demonstrates extreme aggression toward humans she deems harmful to the environment and/or animals. However, she can use her voice in other ways as well.
**SCP-8159** also possesses the ability to force an individual to speak the truth.
When **SCP-8159** uses said ability, her voice emits a very low-frequency sound, almost impossible to hear normally. This tone seems to bypass cognitive resistance, forcing subjects to answer questions truthfully.
Subjects often describe the experience as "irresistible," with several reporting a sense of relief or catharsis after the event, though this varies depending on the individual’s mental state.
Despite **SCP-8159**’s feral hunting tendencies, she appears to be highly intelligent, capable of speaking fluently in multiple languages, including English, Spanish, Mandarin, Japanese, and Dutch.

**Addendum 8159-A**: Discovery
**SCP-8159** was discovered in the Pacific Northwest after foundation operatives were dispatched to investigate the sudden disappearance of several hikers, last seen entering a forest in Oregon known for illegal logging and poaching activities.
**SCP-8159** was located in a forest clearing, seemingly cleaning herself off after a recent kill.
When she was confronted, she politely requested to finish washing the blood off of her hands and face before she went with them.
**Addendum 8159-B**: Experiment log
**Test 1**: //Effect on Animals//
A small female cow, around 2 years old, was introduced into **SCP-8159**’s containment.
She was instructed to use her Sleep Tone on the cow, and she hesitantly obliged.
The cow was entranced by **SCP-8159**’s vocalizations, and after about ten (10) seconds, it had died.
**SCP-8159** expressed remorse for killing the animal, and proceeded to sit next to the corpse, gently stroking it behind the ear until foundation personnel came to collect it for inspection.
The cow’s apparent cause of death was sudden cardiac arrest, and it appeared to have died painlessly in its sleep.
**Test 2**: //Effect on Humans//
A male D-Class personnel, **D-56831**, was brought to **SCP-8159**’s containment, selected specifically based on his extensive history of arson.
**SCP-8159** was not given any prior context regarding **D-56831**’s crimes.
Upon entering, **SCP-8159** began to sing a gentle tune, immediately catching **D-56831**’s attention and luring him towards her.
Once the D-Class was close enough, she promptly pounced at him.
**Autopsy**
**D-56831**’s body sustained severe trauma inflicted by **SCP-8159** during the encounter.
Injuries included a collapsed right lung, cervical spine fracture, and a complete dislocation of the mandible, which was found 6 hours later in **SCP-8159**’s containment, partially buried in the soil about 3 metres away from the artificial freshwater stream.
Additionally, **D-56831** suffered large avulsions and compound fractures, with extensive loss of soft tissue and bone caused by **SCP-8159**’s bite.
**D-56831**’s cause of death was determined to be exsanguination due to the extensive injuries.
------
**Addendum 8159-C**: Incident Report
On ██/██/████, A D-Class subject with a history of animal cruelty and illegal fishing was being escorted past **SCP-8159**’s containment area en route to another test site.
**SCP-8159** detected the D-Class’s presence, and immediately initiated an anomalous vocalization that hypnotized both escorting personnel, and D-Class, compelling them to override security measures and open the door to her containment area.
Upon exiting her enclosure, **SCP-8159** made a direct attack on the D-Class.
The breach was interrupted by on-site response teams with counter-hypnosis audio devices.
During the effort to recontain her, **SCP-8159** accidentally struck one of the female staff members, Dr. ██████.
Dr. ██████ suffered a fractured wrist and superficial cuts. After **SCP-8159** had noticed this, she momentarily ceased aggression, appearing distressed.
She repeatedly apologized to Dr. ██████, and complied with subsequent containment directives without resistance.
**Post Incident Analysis**:
**SCP-8159** expressed no remorse for the breach itself, simply stating that she saw an opportunity to remove filth from this world.
However, she demonstrated genuine remorse for injuring Dr. ██████, frequently asking about her well-being after recontainment, and requesting that her actions not be misunderstood.
**Containment Update**:
As a result of this incident, **SCP-8159**’s vocal activity is to be monitored more rigorously, and her containment area upgraded with additional security measures.
Reclassification to Keter is pending.

**Addendum 8159-D**: Interview log A
[[div class="blockquote"]]
Interview Log 8159 - A
Interviewer: Dr. ██████ █████
Interviewee: SCP-8159
Date: ██/██/████
Location: Observation Room 12-B, adjacent to SCP-8159’s containment area
**[ BEGIN LOG ]**
**Dr. █████**: Good morning, SCP-8159. Thank you for agreeing to an interview.
**SCP-8159**: We’re starting with pleasantries, are we? Very well, then.. And please, call me Nyssara. "SCP-8159" is a mouthful, I think we both agree.
**Dr. █████**: Alright, “Nyssara,” I have a few questions for you, if I may begin..
**SCP-8159**: Ask away, little sprout.
**Dr. █████**: What drives your… unique behavior towards humans? Specifically, what drives you to act one way with some humans, and another way with others?
**SCP-8159**: It’s simple, really. Some people walk lightly on the earth, and others stomp through it, leaving destruction in their wake. The ones who stomp... Well, they don’t deserve the privilege. The ones who tread lightly? They’re rare. And I like rare things.
**Dr. █████**: So you’re saying your actions are based on a kind of moral code?
**SCP-8159**: I prefer to call it “Balance”.
**Dr. █████**: I see. Do you see yourself as an enforcer of that balance?
**SCP-8159**: Enforcer is such a harsh word. Think of me more like... a gardener. Pruning what’s overgrown, giving space for what’s good to thrive.. But make no mistake, doctor. Pruning requires a sharp blade.
**Dr. █████**: You raise some interesting points, Nyssara. I can see where you’re coming from. We certainly… aren’t perfect. I’ve never claimed otherwise.
**SCP-8159**: Oh, would you look at that. A human with but a shred of self-awareness. I might just faint.
**Dr. █████**: Back to the questions. Let’s discuss your... hunting habits. Specifically, your "sleep tone." You said it’s painless, yes?
**SCP-8159**: Painless and without fear. The sound is designed to soothe them to sleep, before they simply die.
**Dr. █████**: I see. The Heifer we gave you to test your Sleep Tone. The autopsy results say that it died of sudden cardiac arrest.
**SCP-8159**: But she died in her sleep, yes?
**Dr. █████**: …Correct.
**SCP-8159**: Therefore, her death was painless. My sleep tone is designed to put the animals to sleep, before shutting their body down to ensure they die peacefully.
They give their lives to sustain me, the least I can do is offer them a gentle end.
**Dr. █████**: …We noticed you showed some remorse after killing it. Can you elaborate on this?
**SCP-8159**: It wasn’t her time. I wasn’t happy that I had to kill her so prematurely, but I understand your curiosity.
**Dr. █████**: I see. Moving on, Can you explain why you specifically target certain types of humans?
**SCP-8159**: Why do I target them? Because they’re the ones who take without giving back. The ones who tear down forests to build their monuments to greed. Who poison rivers and call it "progress." Who kill without purpose, without thought, just because they can.
They leave scars, Doctor. Scars on the earth, on the creatures they destroy, on everything they touch. I see those scars, feel them, hear them. And it’s my job to make sure they don’t make any more.
**Dr. █████**: I see. So, in a sense, you’re almost like a… force of nature yourself. A sort of… vengeance of the wilderness. But my next question is… what makes you think you have the right to dispense that vengeance? Who made you the arbiter of balance?
**SCP-8159**: The Crescent Mother. She’s the one who shaped me, gave me my purpose. She doesn’t ask for much—just that I keep the balance. That I protect what’s worth protecting and deal with what threatens it. She doesn’t care about your rules or your hierarchies, and neither do I. The balance is fragile, Doctor, and someone has to guard it. If not me, then who? I don’t remember signing a contract, no divine decree or council of spirits handing out titles. But the Crescent Mother made me this way for a reason, and I’m not about to let her down.
**Dr. █████**: You say the Crescent Mother shaped you, gave you your purpose. Can you elaborate on that?
**SCP-8159**: She’s not easy to put into words. She’s not a person, not a god—not in the way you think of gods. She’s... the pulse of the earth, the rhythm of life, the quiet voice that hums through the roots and the soil. She’s balance, personified.
She didn’t shape me with words or commands. It was more… instinctual. Like the way the seasons know when to change, or how rivers know their paths. She placed me where I needed to be, gave me the tools I’d need, and trusted me to act when the time came.
She doesn’t demand obedience or worship. She doesn’t scold me when I falter. She simply is, and that’s enough. Her presence is constant, a quiet reminder of what’s worth protecting. Everything I do, I do for her—for the balance she represents. Not out of duty, but out of respect.
**(pause.)**
I don’t expect you to understand. Humans and your kind of gods… it’s a whole different thing. But maybe you’ve felt her presence before—out in the wild, in a place untouched by your machines, where the world still breathes freely. That’s where she’s strongest. That’s where you might hear her, if you listen.
**Dr. █████**: So, the Crescent Mother… her presence or influence over you must be substantial, given its role in forming your ‘purpose.’
(She pauses, carefully phrasing her next question.)
What would happen if it were… removed? If you were separated from her influence?
**SCP-8159**: Removed?
(pause)
You don’t ‘remove’ the Crescent Mother. She isn’t something you can pluck out like a thorn or switch off like a machine. She’s not a tether holding me back or some kind of leash you can cut. She’s... everything. The foundation of what I am, why I exist.
If, somehow, you could sever her from me? It wouldn’t be like flipping a switch. It would be more like shattering a mirror—chaos, fragments, no way to put it back together. Without her, there’s no balance, no purpose. Just a void.
And let me make this clear: I don’t think you’d like what came out of that void. The Crescent Mother keeps me steady. Without her, there’s no restraint, no focus. Just hunger and fury. You think I’m dangerous now? You don’t want to see me without her guidance.
Whatever you’re imagining, whatever experiment you’re considering, don’t. Not for your sake. For everyone else’s.
**Dr. █████**: You speak so highly of the Crescent Mother and her balance, but... aren’t your actions a contradiction of that? You claim to protect balance, yet you take it upon yourself to end lives. Isn’t that, in itself, an imbalance? What gives you the right to decide who lives and who dies?
**SCP-8159**: What? You think I enjoy this? That I want to play executioner? I don’t decide who deserves to live or die—their actions do. The scars they leave on the world scream louder than any plea for mercy ever could.
You sit here, safe behind your walls, pretending you understand what it takes to keep the balance. You don’t. You’re no arbiter of balance, no guardian of the natural order. You’re just another human trying to bend the world to your will, and you have the audacity to question me?!
(The interview escalated when SCP-8159 suddenly stood up from her chair, addressing **Dr. █████** by her full name, despite never being told her name. Security personnel intervened, escorting SCP-8159 back to her cell and ending the interview prematurely.)
