For one hundred and eighty-eight years, Eryndor has thrived on a single, absolute truth: there are no variables.

In cities built on mathematical perfection, time is not measured - it is enforced by the tolling of the heavy bells. Beneath the streets, the ancient stone Covenants bind the very fabric of reality into flawless alignment. No deviations. No disruptions. Everything is accounted for.

The system is perfect. Or so they believe.

When a quiet archivist named Izan Veyr discovers a locked record buried deep within Vael Tareth, the illusion cracks. He has found something hiding inside the ancient lattice of agreements. Something unwritten. Unnamed. Impossibly patient.

In a world built on the terrifying certainty that nothing unpermitted can exist, something is already waiting in the dark.
