Users possess supernatural castle(s), unique and extraordinary castles that are imbued with supernatural and/or magical forces and energies that flow through the entire structure. Even the land around the castle can possess supernatural properties that give them their power and strength in all the specific areas and design structures of the castles.
These kinds of mythic castles are imbued with supernatural properties and elements that can make them semi/sentient dwellings; this can give the entirety of the castle's powers for unique rooms, corridors, buildings and everything that make the castles. Many castles have a different purpose in being, as they can serve as homes for anyone who lives in them in the first place (traditionally royalty) or for an entirely different purpose beyond a just kingdom.
Users can harness the power of the castle as a conduit, which grants them powerful abilities that most inhabitants wouldn’t, especially to those who would possess a throne as the seat of power or something entirely different that grants access a higher power such as the potential to have lordship over the castle and everything and everyone on/in it due to their greater powers and functions of the castles as making them powerful masters.
The people, animals or mythical creatures of the castle can use fragments of the supernatural energies in the castles, including different rooms the castle. Each room has a different function that grants supernatural powers that serve the castles and the people. Most inhabitants can inherit supernatural qualifies and even powers that come from the castles.
