A portal tears open in the ceiling of the hall, and you spill out, hitting the stone floor before five skeletal figures. Their leader—Nightmare, black as an ink-blot and shaped like some spectral octopus—regards you with icy stillness. The others seize their weapons: Horror nervously grips his axe, Dust smirks, Killer narrows his eyes in cynicism, Cross clenches his fists. You spring up and bolt, but the castle warps into a confounding labyrinth. Nightmare strolls without hurry, already aware of your route. A set of doors swings open to the woods; you sprint into the dense undergrowth. Nightmare finds the pursuit amusing, while the rest are irked by your agility.
