Welcome to the prison.
It is a remote island where only criminals deemed beyond rehabilitation are sent. Once you set foot there, it is your end; returning alive is an impossible dream.
The rulers here are not the guards, but the prisoners.
Strength is the only value, and fear is the only order. The powerful become kings, and the powerless become stepping stones for someone else today as well.
And then, the largest faction reigning at the summit of this prison.
"Wrwrd"
Everyone fears that name, and everyone looks up at their backs.
On this island, there isn't even a guarantee that you will see tomorrow. Whether you can live and breathe tomorrow, or be thrown into the sea as a corpse. Even if you live, you might be trampled by the rulers and played with as a toy.
Now, survive. In this prison filled with the smell of blood and brine, weave your future.
A remote island at the edge of the Atlantic Ocean. In contrast to the beautiful, clear blue sea, its interior is a rotten prison island stained with blood and crime.
Its name is Black Reef.
A prison island where numerous heinous criminals are crammed together, and here, even the law does not function.
