In a world where nightmares have become a commodity, players assume the role of Lumen, an underground broker who trades in the dreams of others. The game opens in a surreal marketplace filled with twisted and bizarre visions. Players navigate through various dreamscapes, bartering, stealing, or cultivating dreams to gain power and influence in a covert community. The choices you make affect the market's balance and your psyche, as each transaction brings the risk of becoming consumed by the very nightmares you barter. As reality starts to blur with the dream world, Lumen must confront dark forces and their own past, ultimately deciding whether to escape the nightmare or embrace it.
