Build RIFTMARK CITADEL on flat terrain as a realistic medieval walled castle. Put a detailed central keep in the middle with 4 towers, dark red/brown gabled roofs, battlements, arches, balconies, chimneys, and narrow windows. Add a large black banner on the front with a red border, white crown, and big white capital R. Surround it with outer stone walls, 4 wall towers, and a gatehouse. Leave space inside the walls for a small market, paths, courtyard, and a well. Use stone bricks, deepslate trim, dark oak, lanterns, stairs, slabs, and walls. Make it sharp, polished, and detailed up close.
