A robot yearns to remember. A thief struggles to forget. A galaxy on the verge of collapse.

On the fringe of a broken civilization, a robot awakens with no memories and only one directive: find his creator. But in the village of Korthe, Beetro finds only radioactive pestilence, famine, and Miree-a tormented thief with dreams of retiring after her final score. Meanwhile, the fiefdom is plunged further into chaos when a new warlord seizes control, recasting serfs as refugees and leaving derelict robot peasants in his wake. With a shared interest in survival, Beetro and Miree team up to pull off an impossible castle heist: steal a single flake of dark matter, the world's most valuable and mysterious ore.

But as they trek through the feudal wasteland in search of answers, they realize the true extent of the chaos surrounding them: the stars are disappearing from the sky and the entire galaxy is unraveling. As he uncovers his origin, Beetro discovers he may be the key to the salvation of the cosmos-or its destruction. Time, space, and loyalty become relative as he learns the real reason he was created.

A mind-bending science fiction epic with the bones of a fantasy traveling quest, Dark Theory unfolds through a journey of betrayal, identity, and unlikely friendships in a world of darkness set at the edge of space and time.
