Castle Structure

A castle structure in a future update would provide a new, magical, experience that would enhance the already beautiful Minecraft terrain. This castle would not be a stereotypical fairytale castle with princesses, princes, kings and queens, instead, capturing the more fantasy side of Minecraft. I would imagine this structure to be rare, and located in the woods, doesn't matter which type of woods, just the woods. Since there's so many structures with hostile mobs you have to fight to get even a hint of the perks of the structure, to balance it out, this whimsical adventure would have peaceful, magical, mobs that live alongside the player(s). Each mob would have a purpose, like fairies that act like villagers and traded loot, giant butterflies that you can tame that mimic the behaviors of Allays and fly like bats. This structure's dynamic would be peaceful, and like a village, naturally, this would require an iron golem type mob, this is where the Nesting Dragon comes in. Its stationary like a Shulker Box, and peaceful unlike its ender cousin, it has its own room in which most of the valuable loot is located, the center of the castle. Perhaps it is laying on top of it and you must dig like the Desert Temple? Ultimately, this castle would shift the focus of exploration and survival combat to peaceful discovery. It would give players a magical sanctuary to discover, trade, and take a break, adding a breath of fresh air to Minecraft's nonstop adventuring and survival loop.
