The Dragonet Prophecy is the very first book in the Wings of Fire series and the only one to feature a MudWing as the protagonist. It features Clay as the main character.
Clay and his friends have grown up under a mountain, secretly raised by the Talons of Peace to fulfill a mysterious prophecy. The five young dragons are destined to end the war that's been raging between the tribes of Pyrrhia — but how they'll do this, none of them knows.
But not every dragonet wants a destiny. When one of their own is threatened, Clay and his friends decide to escape. Maybe they can break free and end the war at the same time — or maybe they'll risk everything...
Hvitur is seen trying to escape SkyWing territory with an egg of the SkyWing prophecy dragonet. He is caught by Princess Burn and two of her guards. Burn asks him what he was doing with the egg and reveals that he is a part of the Talons of Peace, a secret peace movment who is trying to stop the war. She throws the SkyWing egg off the cliff, stabs Hvitur with her barbed tail, and throws him off as well, killing both him and the unborn dragonet.
Some time later Kestrel comes and looks at the dead body of Hvitur and the broken egg. She goes into the caves under the mountains and tells Webs that Hvitur and the SkyWing dragonet are both dead. Webs tells her that Asha, another guardian, is dead too and was caught in the middle of a battle. Kestrel suggests that they should abandon the prophecy plan, but Webs convinces her and says he will get a RainWing egg to replace the SkyWing.
Part 1: Under the Mountain
It starts off with Clay practice-fighting Kestrel, one of the guardians of the dragonets. She tries to order his to fight back, but Clay says he would rather stop and talk about it. She finally takes down Clay and starts yelling at him about how clumsy he is. He hears Kestral hiss and he ducks behind a wall of stalagmites to hide from her fire blast. She calls him a coward and continues fighting him. She stamps down on Clay's tail and Clay accuses her of cheating. Kestral says that what she does isn't cheating, and that he should get up and fight back like a SkyWing. Clay says he would rather fight one of the other dragonets, and Kestral asks if he'd rather fight the lazy RainWing or the stunted SandWing. Clay starts backing Glory up, but Kestral tells him to stop yammering. Clay tries to jump away, but slams into the side of a stalagmite instead. Kestrel continues to boss him around. Suddenly she gives a roar of pain and turns around to see Tsunami (the SeaWing Dragonet of Destiny). She tells Kestrel to stop bullying Clay. Kestrel goes on about how she saved her life when Clay (as a dragonet) tried to kill Tsunami while she was still in her egg. Tsunami tells her how annoying it is for Kestrel to keep on reminding them about it, and takes Clay to see the others. Tsunami tells Clay to jump in a river to help his wounds feel better. He disagrees, and Tsunami throws him in instead. They both lay down and look up at the stone ceiling and they both go into a conversation about how Tsunami could be a lost SeaWing princess like she read about in a scroll once. Clay imagines what his parents were like, and what they did when they went missing. They both agree that they'll both save the world first and then find their families. Tsunami then realizes that they should leave sooner instead of wait. She tells Clay to think about it, and she rushes off to dinner, leaving Clay to wonder about she said.
