Black Banner Legion Portal Expedition Concept Art

Full prompt

Epic dark fantasy concept art painting of a colossal, unstable arcane portal glowing with eerie teal flames amid rolling gray mist, bridging a bleak jagged canyon to a haunting alien dimension. A massive Black Banner army of armored infantry phalanxes and heavy cavalry marches toward the threshold like an unstoppable iron tide, with endless black battle standards blotting out the storm-swept sky under oppressive storm clouds. A winding mountain path leads through the rift toward distant floating cyberpunk sky-city ruins shrouded in luminous haze. Impasto digital oil painting texture, ultra-wide cinematic perspective, dramatic chiaroscuro lighting, deep atmospheric haze, and monumental sense of scale, 9:16 aspect ratio.
