Deathwing is defeated when he turns back into Neltharion and he tries to cope with it all. Dealing with the torture he went through, the whispers of the Old Gods, the fear he has of returning to Deathwing and hurting again, the guilt he holds, and the hate others have towards him, he tries to piece his life back together—or what little remains of it—while trying to redeem himself.
When an unknown rabid alien species is let loose on Equestria, chaos takes hold. With all hope of defeating the creatures gone, the one thing that can save Equestria awakens from its slumber: the Predator.
