Gaia and the Hero of Destruction

Shadow, the Hero of Destruction, is sent into the world of Gaia to protect a chosen warrior and help save the planet from its total destruction. However, as Yveltal's chosen hero of destruction, will she be able to prevent what so naturally comes to her. And, will she be able to fill the dark void gouged deep into her heart by the beast's power, or will she remain in oblivion. OC
