A dark medieval royal keep, central seat of a cold mountain kingdom famed for blacksmithing. Heavy fortified stone castle, three stories, built from deepslate bricks, cracked stone bricks, and andesite, with dark oak timber accents. Steep spruce-shingle roofs on two tall square watchtowers flanking a reinforced arched gatehouse. Narrow slit windows, crenellated battlements, an iron portcullis. A forge with a smoking chimney built into one wing. Cold, grim, defensive fortress style — dark and imposing. Roughly 30 blocks wide, 24 deep, 28 tall. Interior with a stone great hall, throne on a raised dais, and a central hearth.
