One city with focus on "Agora Hall" in a retro-futuristic style from the 1950s

one city with focus on "Agora Hall" in a retro-futuristic style from the 1950s. The hall should be filled with people, all dressed in retro-futuristic attire. Some are wearing sleek, mid-century modern clothing with futuristic twists, while others are in uniforms reminiscent of a spacefaring society. A few individuals are clad in ornate, battle-ready armor with a 1950s sci-fi aesthetic. And the walls feature geometric patterns and futuristic murals. The atmosphere is bustling, capturing the energy and diversity of this imagined society. The overall scene combines vintage futuristic design with a sense of community and readiness for adventure
