Aurora Citadel Castle
Just felt like building a huge castle.
Was built in Reforged Eden 2 but should be fine in vanilla
Complexity 50
Has no modules or boxes at all, so if ya wanna bring it into survival you might want to check it out in creative first.
May not be structurally stable, i added some pillars underneath to sink into the ground when spawning.
Spawning it on a lake or ocean might be easiest
