Amidst a backdrop of crumbling worlds and fading shadows, players are thrust into the sinister and ever-shifting labyrinth called Nightreign, a reflection of the Erdtree's wretched decay. Empowered by fragments of lost abilities, equipped only with their valor and ingenuity, you and your impulsive partners must venture through procedurally generated corridors filled with terror, cunning traps, and grotesque abominations. Forge your path as you scavenge runes to unlock corrupted powers, face the haunting echoes of betrayal or brotherhood, and confront harrowing mini-bosses that calculate your greatest fears. Will you escape the clutches of madness, unravel the mystery behind Nightreign, or will you become yet another lost soul tethered to its nightmarish embrace? Your survival is a perilous journey—choose wisely.
