The arrow's shaft gleams like polished obsidian, fletched with feathers black as a starless void, its iron tip etched with writhing shadows that seem to pulse faintly. Nocked to the string, it hums with an unnatural chill, drawing in nearby light until the air around it thickens to inky murk. Released, it streaks through the air, trailing tendrils of darkness that swallow sound and sight in its wake.
