Create a dark fantasy book cover, digital painting, for "The Blood of the Heir" by I. Constantine. The scene should be gloomy and grey, with touches of red to signify blood. In the foreground, place a young boy, about 16 years old, dressed in dark knight armor. He should be standing resolutely. Behind him, the indistinct, shadowy form of a six-headed dragon looms, its details obscured to maintain a sense of menace and mystery.
