Build RIFTMARK CITADEL on flat terrain at player scale as a realistic medieval walled castle. Make it feel good to walk through, not oversized. Use mostly deepslate tiles and stone bricks, with dark oak for beams/details. Put a detailed central keep in the middle with 4 towers, battlements, arches, balconies, chimneys, narrow windows, and dark steep roofs. Add outer walls with 4 wall towers and a large front gate gatehouse at the entrance. Leave space inside the walls for a small market, paths, courtyard, and a well. Add a large banner on the FRONT of the central keep made from red, white, and black wool, with a white crown and big white capital R. Make it clean, sharp, medieval, and detailed up close.
