A muscular Valkyrie style Norse warrior riding a fantastical huge white beast in a rugged, mountainous landscape. The warrior, with a rugged, bearded face and long, dark hair, is dressed in medieval-style attire consisting of a sleeveless brown leather vest, brown trousers, and brown boots. He wears a belt with a sheathed sword and a quiver of arrows. His expression is determined as he rides the massive beast. The white beast is a mix of a dragon and a lion, with sharp, curved horns, a long, muscular tail, and a fierce, open-mouthed expression revealing sharp teeth. Its eyes are yellow. The creature's fur is sleek and white. The warrior holds the reins with one hand. The background is a dramatic, partly cloudy sky with a deep blue hue transitioning to a lighter blue at the horizon. The ground beneath them is rocky and uneven, with patches of grass and sparse vegetation. weapons, axe, hammer, dramatic lighting, yellow sphere on the background
