In the frozen wastelands of the far north, where the remnants of the once-great Crystal Empire lie buried beneath endless snow, a strange pony awakens in a shattered lab with no memory of who he is or how he came to be. With nothing but his name, Tenebrae, and a burning desire to survive, he must navigate a world twisted by necromantic magic and inhabited by nightmarish creatures born of the Wailing Frost.

Joined by Flitter Light, a young unicorn apprentice of the Illuminators, Tenebrae embarks on a harrowing journey through the hostile wilderness. Together, they face the horrors of the Frost—cannibalistic Snow Ponies, mutated abominations, and the ever-present threat of the fog itself, which twists fear into a deadly reality. During their journey through madness and despair, Tenebrae slowly uncovers the dark secrets of his past and the true nature of the Wailing Frost, a curse that may be tied to his own forgotten identity.

In a world where light is a precious commodity, and hope is a flickering flame, Tenebrae and Flitter Light must find their way through the darkness—or be consumed by it.
