A massive shinobi wizard tower built on top of a rugged mountain in a spruce forest biome, overlooking a dark oak forest valley. The tower is tall and cylindrical like a wizard spire but designed with Japanese shinobi and feudal architecture. The structure is made of dark stone, spruce wood, and dark oak with multiple layered pagoda-style roofs that curve slightly upward at the corners. Lanterns hang from wooden beams and balconies. The tower serves as an ancient “Archive of Forbidden Jutsu,” filled with magical scrolls and secret ninja knowledge. Purple amethyst crystals float around the tower emitting magical energy. Red banners with mysterious shinobi symbols hang from the walls. The entrance is hidden and guarded with torches and stone steps carved into the mountain. h 100 w 50
