Cover for a dramatic fantasy WebNovel. A young man stands on a battlefield holding a dagger, his face determined but sorrowful. Behind him looms a dark humanoid demon symbolizing inner conflict. Mood: intense and emotional. Colors: dark blue, crimson, shadows. The cover should reflect the struggle between three personas: a devil, a modern man, and a child. Subtle ghostly silhouettes or light hints may suggest fractured identity. Title: The Mad Immortal. Author: CircleGray.
