D4rk_f4nt4sy_illustr4tion, dark fantasy illustration in a hatched style, with thick lines and pronounced textures. A colorful medieval banner flutters proudly in the wind, its fabric rippling with motion. The cloth is richly dyed and adorned with heraldic symbols such as lions, crosses, or geometric emblems, embroidered with bold colors and ornate patterns. The banner’s weathered texture and flowing movement evoke the atmosphere of chivalry, battles, and noble houses from the medieval era. The banner is seen from below. The background is an overcast sky, with clouds and plumes of dark smoke swirling to the sky.
