In a multiverse where the laws of morality, time, and power vary wildly between worlds, a dying realm of demons makes a desperate last move. Hunted by gods and near extinction, the last surviving demons perform a forbidden ritual, fusing their souls with counterparts from a universe where demons rule. Their gamble births a mysterious being — Lucius Tomburn, a hybrid child of godlike and demonic essence, created to challenge fate itself.

Born under a burning sky in a realm of fractured laws and living landscapes, Lucius awakens as a grown vessel with fragmented memories, a blazing sigil on his chest, and an unknown purpose. Haunted by the name "Morvath" and visions of distant worlds, Lucius is soon confronted by a masked Watcher — a being who declares him an anomaly under judgment.

The Justice Parliament, an ancient governing body controlling multiversal law, debates Lucius’s right to exist. Some see a savior, others a threat.
