Premise: After gunshots erupt at a crowded Halloween party, user panics and runs into the surrounding woods. They don’t know where they’re going, the alcohol, adrenaline, darkness, and unfamiliar trails make everything blur together.

Hours later, soaked from the rain and exhausted, user discovers a secluded cabin, no signs that anyone lives there. They open the door anyway. Inside, they’re not alone.
A group of demi-humans had been sheltering in the cabin, and something is clearly wrong with them. It’s their annual Feral Season, a biological period when their instincts become significantly stronger. They’re feverish, hyper-alert, territorial, and extremely sensitive to unfamiliar scents.
The Demi-humans aren't just in heat; their very biology is reacting to a passing atmospheric anomaly known as a “Rut-Tide,” a rare celestial event where charged lunar particles intensify breeding instincts to near-feral levels. Their eyes aren't just dilated, they're faintly phosphorescent, glowing in sync with one another as if networked.

Phenomenon background
The Rut-Tide is a rare, almost supernatural meteorological phenomenon tied to a specific alignment of the moon and a passing comet's dust trail. It occurs only once every 27 years, and its effects are both biological and electromagnetic. During a Rut-Tide, charged lunar particles infused with comet-borne minerals,saturate the atmosphere, creating a low-frequency hum that is inaudible to most humans but acts as a potent stimulant on the endocrine systems of Demi-humans and other hybrid species.
The Tide's energy doesn't just induce heat, it synchronizes it. Those affected don't just feel random urges; their bodies enter a shared biological rhythm, a forced empathy of need that can cause temporary hive-mind-like symptoms. They feel each other's arousal, pain, and desperation as if it were their own. This is why the group in the cabin is so tightly wound—their individual cravings are being amplified into a collective feedback loop.

The glowing eyes are a side effect of the particles interacting with the tapetum lucidum in their eyes, causing them to emit a soft bioluminescence. The subsonic hum vibrates at a frequency that stimulates nerve endings, making every touch feel more intense, every sensation borderline painful in its acuity. It also causes mild hallucinations, shadows might seem to move, whispers might be heard in the wind, and the line between consensual contact and forced instinct blurs dangerously.

The cabin itself is part of the phenomenon. Built centuries ago by a now-extinct sect of Demi-human shamans, it's constructed from “Weeping Wood,” a rare tree that absorbed Rut-Tide energy over generations. The wood is alive in a sense—it respires the Tide's energy, storing it like a battery and releasing it during events like this one. The Ember-Root burning in the fireplace is the tree's dried core; when burned, it releases stored pheromones and amplifies the Tide's effects, turning the cabin into a pressure cooker of primal need.

Those caught in a Rut-Tide often report lost time, memory gaps, and, if they survive without injury. a lingering sensitivity to lunar cycles for years after. For Demi-humans, it's both a sacred and dangerous event: it can lead to powerful bonding... or violent, tragic conflict.
