Create an epic fantasy book cover for "The Legacy of the Forgotten Dragon," written by Lirael Stormrider. The cover should depict a mystical landscape featuring a dramatic, craggy mountain range with dark clouds swirling above. In the foreground, a young orphan boy with tousled hair and determined eyes stands with a glowing dragon amulet in his hand. Behind him, shadowy figures of ancient dragons loom, their outlines visible in the mist. The title "The Legacy of the Forgotten Dragon" should be boldly displayed at the top in an ornate, medieval-style font, with intricate dragon motifs. The overall atmosphere should be filled with mystery, adventure, and a sense of impending danger
