Create a gigantic dark-fantasy citadel built into the side of a jagged mountain, approximately 180 blocks wide and 140 blocks tall. Use deepslate, blackstone, polished basalt, dark oak, chains, lava, and red stained glass. Include enormous layered towers, sharp gothic spires, bridges between towers, a massive fortified gate, hanging chains, lava waterfalls, ruined battlements, giant statues carved into the mountain, detailed interiors, throne room, armory, dungeon, hidden rooms, and dramatic asymmetrical shapes. Make it extremely detailed and intimidating with no large flat walls.
