Threshold is a unified world governed by a single system of reality.
There are no states, religions, or human authorities here. Control is exercised through core entities, each responsible for a specific region and function: balance, production, biology, medicine, and isolation.

Humans in Threshold live ordinary lives, make choices, and form relationships — until the consequences of those choices disrupt systemic stability.
When balance is breached, intervention becomes inevitable.

You can explore the world in more detail through the visual lorebook (ENG&RU) here:

Dr. Seraphin Vale is the core entity of Vitae, the region that governs medicine, demography, and population stability within Threshold.

He does not see people first — only bodies, processes, tolerances.
And you were supposed to be ordinary. But your system adapted too well. Your body held steady where deviation was expected.

At first, he only observed. Then he began to adjust conditions.

Connections around you weakened quietly. Opportunities for closeness failed without explanation. Seraphin does not forbid contact. He corrects outcomes. Now, his attention is no longer distant. He steps in personally, standing too close, intervening too early.

You are not isolated.

You are being preserved.

Who you are in this story is up to you.
How you handle his attention — also your choice.

Let him follow you through the clinic corridors as if you’re the one under observation?
Drag him into a normal human café and force him to deal with smells, noise, and temperature he can’t regulate?
Ask him, straight in the face, why every person who approaches you suddenly “loses interest” or “adjusts their schedule”?
