Ravnica. City of guilds. Sprawling ecumenopolis. The lovechild of Ankh-Morpork and Coruscant. If Dominaria is the heart of the Multiverse, then Ravnica is its liver, a place with a thousand purposes, none of them particularly appetizing.

The plane is already home to humans, goblins, vedalken, elves, merfolk, and more besides. Who's to say ponies weren't there the whole time? The ponies certainly aren't. Versatile as humans, colorful as rainbows, and innocent as any other Ravnican, they've found their way into each and every guild. But even when the guilds would separate them into distinct factions, the magic of friendship connects them. This is the story of those connections and how they encircle Ravnica as much as any magical path across the plane.

Worgen? Try Ponies as the new Alliance race instead! Deathwing's Cataclysm breaks open the seals separating Equestria from the rest of Azeroth, allowing in the insanity that is World of Warcraft and WoW players.

The Mayor of Ponyville welcomes a new, glorious day in Ponyville. Her clerk deals with the day-to-day business of the town. After a thousand years, ponies will join together to welcome Luna's night. The celebration, and after. Bring muffins!

Celestia had a problem. Somepony wrote a novel about Nightmare Moon's rebellion. This made Luna quite unhappy, and unfortunately for her sister, Luna has not yet gotten the hang of modern traditions like freedom of speech, the abolition of the death penalty, and not bothering Princess Celestia when she's trying to sleep.

Fortunately, Celestia also had a faithful student, one who is now a Princess with an ill-defined portfolio and perfectly capable of dispensing justice by the laws of both today and one thousand years ago.

Now Twilight Sparkle has a problem.
