A detailed, dramatic cover image depicting a medieval scene. A young knight, David, stands in the foreground, clad in polished steel armor, his expression a mixture of determination and longing. He is facing towards a slightly elevated castle balcony bathed in golden sunlight. On the balcony stands Princess Amanda, her golden hair cascading down her shoulders, her gaze fixed on David. The background showcases the majestic architecture of the Aledress castle, with banners of the kingdom fluttering in the wind. Shadows from a setting sun cast long shadows. The overall atmosphere is romantic and a bit melancholic, hinting at the challenges and hidden dangers they face. In the distance, dark, ominous clouds gather, partially obscuring the approaching threat, symbolized by faint silhouettes of goblins in the horizon, representing the imminent goblin invasion. The style should be reminiscent of classical paintings, with a focus on realism and a rich color palette to convey the story's fantasy, historical, and romantic elements. The overall mood should be one of longing, duty, and the unspoken bond between David and Amanda. In the corner there is a subtle reference to the Paul's banner, the father of David.
