When Queen Celestia has to temporarily leave Equestria on business, she needs someone to look over the kingdom in her absence. Much to everyone's surprise, she chooses the ambitious Sunbeam Sparkle to serve as her regent rather than the steadfast and loyal Shadow Kicker.

However, Sunbeam has little time to ponder why her monarch chose her. The Golden Path of Freeport, a corrupt regime ruled by false gods, sees Celestia's absence as an opportunity. Now Sunbeam must face a foe that claims to be every bit Celestia's equal, and with no divine powers of her own...

For the first time in history, the Archon of Freeport has come to Equestria. Princess Twilight Sparkle has been given the honor to host Archon Sunset Shimmer, but she quickly finds herself at odds with her prestigious guest. Things turn sour when something is stolen from the Archon, and Twilight is the prime suspect. Twilight must uncover the real thief to avert an uproar of international proportions.

A Winningverse story.

Sunset Shimmer, the Magus of Freeport, has taken plenty of jobs since her arrival in the city. Though she's picky about what work she'll do, especially when the job is offered by one of her least favorite ponies in the world, the large bag of gold that came with the latest request was enough to change her mind.

And that's how she finds herself attending a high-end auction, where one of the rarest and most dangerous tomes of magic in the known world is being sold off to the highest bidder. With some of the world's wealthiest scum and villains attending, who walks out with the book could have consequences far beyond the islands.

Sunset Shimmer is on the run. It's been six months since she left her life as Princess Celestia's student behind, but she can't escape her own past. Her parents are offering a reward for her safe return home, and Celestia's agents are watching her every step. She might have gotten out of Canterlot, but the runaway student is still a long way from freedom. Especially since her education with the Princess of Equestria didn’t cover things like how to make a living wage with her magical skills.

However, there might still be one place where she can escape all of them. The infamous island nation of Freeport has long had a reputation as a haven for pirates, criminals, and exiles, but there's no better place in the world for somepony who wants to disappear. The only question is whether Sunset will live long enough to pull it off.

Twilight Sparkle has spent months researching chaos magic, developing a new spell to unlock magic nopony has ever experienced before. But when something goes wrong with casting, Twilight finds herself turned into a Draconequus and unable to control her new chaos magic. If she ever wants to be a pony again, there is only one who can help her learn to control her new magic.

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.
