Build a large symmetrical gothic opera cathedral stage made of blackstone and deepslate with a tall circular central podium covered in massive flowing red drapes shaped like an elegant dress, with a central staircase leading upward into the draped structure, surrounded by ornate gothic arches and balconies like an opera house interior, illuminated by dramatic red lighting, fire, and infernal glow, architecture only with no characters, statues, or humanoid figures.
