Create a charcoal and chalk drawing. The scene shows a king in black and gold armor seated on a black Pegasus with matching armor, positioned on top of a large hill. The king is overlooking a battlefield far below. His army, dressed in black armor and mostly mounted on horses, is in a grassy field facing the enemy, who are clad in silver armor. Banners are fluttering in the wind. The view is cinematic from above and behind the king. The sky is dark with rain clouds
