Gato de obsidiana espreitando por um labirinto de livros antigos

A sleek, obsidian cat with emerald eyes prowls through a labyrinthine city constructed from ancient, crumbling books. The sky above is a swirling nebula of ink and stardust. Shadows stretch and distort, hinting at unseen entities. This piece is rendered in a highly detailed concept art style, with a painterly texture and a cinematic, moody atmosphere, inspired by the works of H.R. Giger and the storytelling of Guillermo del Toro.
