A dark night ready for battle

A warrior clad in dark, mystical armor stands ready for battle on a stormy, night-shrouded cliffside, illuminated by flashes of ethereal lightning, with an ancient, ruined castle looming in the background, surrounded by twisted, gnarled trees and eerie, glowing mushrooms, as if conjured from the imagination of Simon Stalenhag, with the atmospheric, cinematic depth of a matte painting by Syd Mead, and the intricate, high-fantasy detail of a Frank Frazetta illustration, rendered in stunning 8k resolution, with a deep, rich color palette and bold, complementary hues, reminiscent of a splash screen from a cutting-edge video game, created with the Unreal Engine 5, and trending on Artstation.
