This story is a sequel to Home is Where Your Curse is

The sorcerers have been defeated. Their artifact stolen from their grasp, their partnership ruined, their presumptive "rebellion" stamped out, and their base destroyed. Although the revolutionaries were not captured, their every plan fell apart to nothing before the arcane wit of Trixie Lulamoon and the martial prowess of Ranma Saotome. Even the mighty dragon prince Kamikazan, the last gambit of the dastardly unicorns, fled before the conquering heroes.
Yet Ranma and Trixie return to Equestria not as heroes, but as fugitives from Equestrian law. The great Serpent King has been weakened and humbled, but still roams the sky once more, seeking his former glory. Blood Rite hides in the shadows, seething with new hatred, his list of grievances running longer as his patience withers. Ever more enemies join the struggle to bring down the mysterious stallion known as "Havoc," leaving a veritable trail of destruction across the countryside. As the old threats fall silent, new ones emerge at pace, and peace seems more distant than ever.
It's a week just like any other for the Wild Horse.

The royal court of Canterlot welcomes its newest member with open forelegs: the human philosopher Voltaire, from Earth.

On Earth, Voltaire is known as the greatest enemy of tyranny in the history of literature, and a legend in his own mind.

On Equestria, the court betting pool is giving him a week before the Princess banishes him to the Moon.

Note: This story doesn't have sequels per se, but there are a couple of short follow-ups set in the present day ("Parade Coverage" and "Secret Histories"), and a prequel of sorts in "At the Inn of the Prancing Pony".

After the Friendship Games, Sunset feels it's time to return home.

Only when she gets there, Twilight's castle is nowhere to be found, Cadance just got her horn, and Princess Celestia is still calling the bacon-haired pony her prized student rather than a failed one. And just reliving her past isn't on the table thanks to a pair of wings Sunset seems to have sprouted upon her return to Equestria.

With Sunset being back before she's supposed to, will the world stay as harmonious and on track, or will everything go down in flames as Sunset has to deal with allegations that she's really a changeling in disguise, a nerdy stallion with blue hair that wants to be her coltfriend, a pretty pink princess in need of remedial magic lessons, and an annoying purple pre-teen pony that will absolutely not go to bed without first being read Starswirl's Complete Mystical Mysteries Compendium?

Only time will tell
