[A dark fantasy, gothic steampunk illustration of a shadowy figure wearing a tall, battered top hat and a tattered, layered trench coat walking forward. The figure's face is obscured in pitch-black shadow with striking, glowing neon-green eyes. The character is holding a paper coffee cup in one hand. Walking alongside him is a sleek black cat with matching glowing neon-green eyes. They are walking on cobblestone stairs covered in intricate, glowing emerald-green ancient runes and symbols. The background is dark, moody, and atmospheric, filled with floating parchment paper notes in a dim, misty green light, vintage comic book art style, low-key lighting, highly detailed, 8k resolution.]
