vintage dark fantasy illustration, style influenced by Frank Frazetta and Angus McBride’s work. High contrast, harsh lighting, vivid colors and oils. A knight in bright steel armor, embellished with gilded ornamentation and a red cloak, splashes in the water of a wide frothing river as he swings a battle axe at a foe. His enemy, clad in darker armor with yellow and green colors, staggers back, wielding a spear. All around them, a vicious battle rages in the rapids of the river, with men in armor and bright heraldic colors engaging in a vicious melee. Weapons and armor flash as they catch the light. Armies line the banks on both sides of the river, with bright banners bearing coats of arms and heraldry flowing in the breeze.
