The Celestial Brass Observatory Through the Stargate Orrery A cosmic steampunk ballroom, entered through a whirling brass orrery, its celestial rings aligning to reveal a shimmering star-lit portal. Beyond lies a vaulted ceiling of rotating mechanical star maps, shifting as unseen gears tick forward. The walls are covered in deep navy and gold, with brass astrolabes and floating planetary orbs suspended in midair. Hanging ivy and golden vines wrap around celestial clockwork mechanisms, illuminated by the soft glow of artificial stars. The air smells of sandalwood, ink, and ancient tomes, evoking a sense of cosmic wonder and forgotten stardust knowledge.
