Pyatak

Pyatak, in Russian, means "slash five". It is the last stop for the most violent and incorrigible prisoners in the modern Russian penal system. Famously, it is said to have two ways in and only one way out. Inmates enter its cages via a dilapidated, one-hundred-year-old foot bridge or an aging boat. The only way they leave is via their grave. Lately, however, many of its worst have gone missing from their cells, although they never escaped its walls.

Something ancient and evil has alighted in Pyatak. A mysterious entity, it is both vicious and insatiable. No one is safe.
