create a picture: couple of medieval halych west-slavic knight and west-slavic lady-knight with armour, with black dragon on the coat of arms, near a river; a black dragon perched on their coat of arms, intricate patterns on their helmets, an ornate gold medallion above their heads, river in the background with numerous boats floating on the water, ruins and statues visible next to the waterfront and on the shoreline, dramatic shadows in the foreground, detailed painting style.
