"They are called the Unbinders... and they'll do everything they can to kill you."

For centuries, the boundaries between realms have held firm, protecting worlds from catastrophic merger. As Blademaster of Urlas, Rukes has dedicated his immortal life to maintaining these sacred divisions. But when an ancient artifact activates in his possession, he discovers a terrifying truth: the barriers are failing.

A brilliant archivist has vanished while researching the mysterious Five Seals—ancient keystones that anchor reality itself. Now Rukes must journey to the fabled city of Kiliari, where the Great Library houses secrets that haven't been disturbed in three hundred years.

What he finds will shatter everything he thought he knew.

The Knowledge Seal lies damaged beneath the Library, and a shadowy faction called the Unbinders works tirelessly to destroy the remaining anchors. Their leader, a being who exists in the spaces between worlds, claims the boundaries were never meant to be permanent.

With the brilliant Kiliari scholar Meridea and the enigmatic djinn Nasira at his side, Rukes races to reach the remaining seals before they fracture completely. Their quest takes them from the frozen wastes of the Frostpeak Mountains to the impenetrable Verdant Jungles, facing entities beyond comprehension at every turn.

But as Rukes's consciousness expands beyond mortal limitations, he confronts an impossible choice: preserve the boundaries as they were, or guide them toward something entirely new—and risk the annihilation of everything he's sworn to protect.

The cosmos trembles at the edge of transformation. The Five Seals await.
