Moonlight struggles through a shroud of heavy clouds, painting wan streaks across the jagged stones of the path. Before you looms a castle of black obsidian, its towers raking the sky like skeletal fingers. The immense iron doors stand open, revealing a corridor devoured by shadow. Long, dark curtains strangle every window, suffocating any hint of warmth. A chill wind whispers through the entrance. You feel a palpable evil presence within, waiting. Do you dare cross the threshold?
