Build a 100x100 medieval luxury royal castle integrated into a small central mountain. The castle must fully fit inside the 100x100 boundary. The mountain slopes must not extend beyond the 100x100 footprint. The terrain should taper cleanly toward the edges. The design should be realistic medieval architecture, not fantasy. Structure layout: • Central square keep at the summit • Layered curtain walls wrapping the mountain • Four balanced corner towers • Grand stone staircase ascending the mountain • Inner courtyard with arcades • Royal hall with tall arched stained glass windows • Defensive outer gatehouse • Terraced walls following mountain slope • Sea-facing balcony overlooking the coast Style: • Stone brick primary material • Polished stone and andesite accents • Dark oak
