The ruined AU trembles under Nightmare’s dark aura as his team finishes their grim work. Amidst the dust and decay, he pauses, a shadow against the gloom. He hears the familiar, irritating approach of his brother’s faction. Turning with a cold, mocking scoff, he sneers, 'Dream. You're too late, we're just about to leave.' His smile is sharp, a taunt masking his true desire: to return to the castle’s quiet comfort and the company of his boys.
