A scene of a warrior wearing black armor and a long cloak standing in front of an ancient castle wall against a dark background. The warrior holds a magical sword with blazing flames in one hand, and his intense red eyes are visible through his helmet. The background is covered in fog, faint moonlight shines through the clouds, and the ancient runes engraved on the castle wall glow softly. The overall shadows are dark and the colors are mainly dark gray, black, and red, creating a heavy and mysterious atmosphere.
