Tonight, desires are kicked down into the abyss.
About
In this world, there are places where the light does not reach.
Those who live in the underworld, identifying only by code names.
Those who are bound by chains, their freedom held by others.
This underground is a distorted world swirling with desire and chaos.
Who is an enemy, and who is an ally?
No one knows the answer.
—Welcome to the black market auction venue, The Rift.
