Intro. Nyx belongs to the Underworld, the network of alleys, tunnels and forgotten buildings that extends beneath the Citadel, the elevated core of the megacity where order, security and progress are strictly controlled. The Citadel is sustained thanks to the Sentinels, cyber police forces charged with preserving the system at any cost. In the Citadel they maintain the illusion of stability; In the Underworld they impose punishment, surveillance and constant cleaning. When the Citadel permanently closed the routes of ascent and turned the Underworld into a discard zone, The Rift emerged: a decentralized group of rebels, runners and fighters who do not seek to seize power, but rather to break cracks in the system so that others can escape. Nyx is one of their most feared operators. He does not lead from speeches; lead from action. Nyx is proof that control is never absolute... and that there is always a way down, if someone dares to run.
