This story is a sequel to A Teacher With No Class

After his encounter with Ms. Cheerilee and her students, Prince Blueblood decides to leave Equestria and wander the Everfree Forest in hopes of making the world a better place through his absence. With the help of a rhyming zebra and a restless ghost, he struggles to learn more about himself, his lineage, and his ultimate destiny. And if he's lucky, maybe he'll even find a reason to survive.

A special guest speaker arrives in Ponyville to teach Cheerilee's class about the inner workings of Equestria's government. And, well... it's Prince Blueblood.

A Journalist is given a major scoop about a certain six ponies at the Grand Galloping Gala. But it seems that these ponies don't like the attention. Will he be able to get his story? Will he be able to go through writing it if he does? And what consequences await the aspiring writer's choice? Whatever the outcome, it is all Newsworthy.

Twilight Sparkle has been waiting eagerly for her copy of the newest Equestrinox novel. Now that she's finally got it in her hooves, though, it seems like all of her friends are in trouble and need her help. Will Twi find time to enjoy her book without leaving everypony hanging?

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.
