The mission is in the name.

Reconnaissance - Detect and evaluate potential threats to Equestria, foreign and domestic.
Assault - Effectively attack & destroy targets of interest.
Interdiction - Interfere with hostile organizations' logistics support.
Demolition - Provide combat engineer support and clandestine sabotage capability.

Such is the mission of the Equestrian government's most secretive organization, RAID. Their precursor, the Royal Guard's 1st SOG-CAD, started the Wonderbolts to attract and evaluate potential operatives. Operating with near-total freedom, their actions have maintained the thin veneer of peace enjoyed by the citizens of Equestria.

Decades later, the Wonderbolts have fulfilled their secretive purpose once again, bringing the young pegasus Rainbow Dash to RAID's attention. Still hoping to one day fly before crowds, she reluctantly accepts the invitation to join. Soon after she completes her training, though, the organization is thrown into a shadowy international conflict that threatens to turn into all-out war if RAID cannot stop it. The coming fire will either temper Rainbow Dash's loyalty to a new strength or melt her in the flames of hatred...

The storm is breaking on the Horizon.

It's been two months since the battle against Nightmare Moon. Luna is recovering, Celestia is busy turning the government back into a diarchy, and the Mane Six have returned to their lives. All seems well, but when Celestia discovers that half of the power of the Elements of Harmony have been transferred to each of the Bearers, she decides to send thirteen mysterious members of the Royal Guard to monitor them as they manifest and develop their new abilities.

The sins of a forgotten war still linger, and an ancient evil lurks in the shadows, just waiting for the right time to strike. The Mane Six suddenly find themselves once again at the heart of a conspiracy to bring about Eternal Night, and only by awakening their powers and realizing their full potential can they do anything to stop it. Friends both old and new will help them along the way, and an unseen force will guide them as it seeks to right a wrong made thousands of years ago. The Bearer's journeys will take them outside the borders of Equestria and into the world beyond, and when they return, they'll have the power and experience necessary to save the world and bring about balance in all things.

For as long as Rainbow Dash could remember, her life was simple, straightforward, and planned out with one goal in mind: become the best flyer in all of Equestria. Simple. But when she unwittingly comes across a tool that allows her to relive the memories of her ancestors, that simplicity is challenged when she discovers dark secrets hidden in her family's past as well as Equestria's history that not only challenge her perceptions of reality, but threatens to alter her very psyche.

As she's thrust into the remnants of a centuries-long war, as she questions the morals of those around her, as she battles to separate reality from fantasy, will Rainbow be able to hold on to her own beliefs or will she embrace her family's blood-stained traditions and finish what they started?
