Nomadic caravan city crossing an alien desert under twin moons

A colossal nomadic caravan city, built upon the backs of gargantuan, ancient beasts, traverses a desolate, alien desert under a sky filled with twin moons. The city structures are a chaotic blend of weathered wood, salvaged metal, and glowing arcane symbols. Wind whips sand across the decks, obscuring ancient runes carved into the beast's hides. The overall aesthetic is a fusion of post-apocalyptic survival and mystical journey, rendered in a highly detailed illustration style reminiscent of The masters of Fantasy and adventure
