Design the homepage and several pages of a website for the Kingdom of Aetheria. The homepage should feature a grand, futuristic welcome with a sleek interface, including a logo of Aetheria, a navigation bar with options such as 'About Aetheria,' 'Citizenship,' 'Technology,' 'Culture,' and 'Contact.' Each page should be visually distinct but cohesive, with a minimalist yet modern design, utilizing the symbols previously created to represent Aetheria. The overall theme should be clean, elegant, and futuristic.
