Long ago, in the magical land of Equestria, there lived a powerful King and his dark Queen. Immortal and ignorant, their end came at the hooves of their daughters, Celestia and Luna, who sought to build a better future for ponykind.
Now ponykind’s old gods have returned.
Twilight Sparkle is trapped inside her own mind, slave to a cruel and impulsive consciousness built from everything she is not. Powerless and voiceless, she must find a way to stop the being that calls itself Nihilus from destroying everything she holds dear.
Luna is tasked with assembling the remaining Elements of Harmony in hopes of freeing their leader. For if ponykind is to have any hope, it is in Twilight Sparkle. And if Twilight Sparkle is to have any hope, it is in her five friends.
Facing her father in mortal combat, Celestia must do everything she can to ensure that ponykind has the tools to survive before she falls. With inevitable defeat bearing down upon her, she makes the first move in the oldest and deadliest game known to creation.
