It's been decades since the war ended, and Pyrrhia is safe once again. Yet, trouble stirs far from the battle-scared continent. On a peaceful land called Hirynar, there is a young SkyWing named Cloudspark. He lives to fight and he never turns down even a quick spar. However, one day he's fighting to become a Brawn, a powerful, gifted SkyWing that leads his or her own squadron. His opponent, Boltcast, is a ShockWing that can electrocute anything he touches. Cloudspark's friends and future squad is worried that he could die. However, that's the least of their worries.
In the middle of the battle, an unknown dragon named Shadelock came and demanded to become ruler of Hirynar. When SkyWing Queen Emerald denies its offer for an alliance, Shadelock destroys the entire arena and kills almost everyone there. Cloudspark, his brother Flintrock, and the rest of the Sky Breakers promise Queen Emerald to hunt down the mysterious menace and bring it to justice. Little do they know, there's a lot more to Shadelock than meets the eye.
