In the posts below will be pictures and a short description of the major locations in Equestria that also serve as the major forum areas of the site. There are more locations within each of these locations, as well as locations not mentioned below. For more detailed information on locations in Equestria, please visit Equestria on the Friendship is Magic wiki.

Ponyville was originally founded by the Apple Family and other Earth Ponies, taking advantage of the famous Zap Apples that grew in the nearby Everfree Forest to grow their apples orchards and the resulting settlement with the money made with Zap Apple Jam. Today Ponyville is home to all types of ponies and nonponies. In terms of style, Ponyville has the look of a country village, with many of the houses having thatched roofs, timber frames, and overhanging upper floors. However, Ponyville itself isn't a simple little village, but instead is a rather large town and is filled with many different businesses from bakeries and libraries to spas and joke shops.
Ponyville connects to the rest of Equestria through a mix of dirt roads as well as a railroad.
Canterlot is the capital city of Equestria, and home to the most elite and high class ponies of Equestria as well as the Princesses themselves. The city has a very fantasy like feel to it, being built into the side of a mountain and containing giant spires and medieval-castle like designs and buildings with rivers and lakes running through it. Many of the major cultural events in Equestria are held here, such as the Grand Galloping Galla and the Canterlot Garden Party. It is about a day trip away from Ponyville.
It is rumored that underneath the city is an extensive cave system that used to be a gem mine.
Cloudsdale is a city located in the sky, built completely out of clouds. Because of this, it is home exclusively to pegasi as earth ponies and unicorns are unable to walk on the clouds without the assistance of magic. The city's design is inspired by Greek and Roman culture, as can be seen by the existence of locations such as the Cloudosseum. Many events regarding weather and flying can be found here, such as the Best Young Flyer competition and the various weather factories that develop weather for Equestria.
The Everfree Forest is probably the most mysterious location in all of Equestria. It is known for not following the normal rules of the world, being the only location in which weather, plants, and animals are self-sustaining without the need of pony magic to manipulate it. Inside the forest are a variety of plants (such as Poison Joke) and animals, many of which are dangerous (such as timberwolves) or monstrous (such as sea serpents, dragons, or Ursas). Because of this, few ponies have been inside the forest, and almost no one lives there (the exception being Zecora). This also makes it a very common place for banishment, or at least that is what the average paranoid pony thinks.
Located deep within the forest are the ruins of the ancient castle where Celestia and Luna used to keep court and former resting place of the Elements of Harmony.
The Crystal Empire has recently returned after being sealed away over one thousand years ago. Formerly ruled by the tyrant King Sombra, who took it with him when he was sealed away, it is now ruled by Princess Cadence and Shining Armor. The city itself is primarily constructed by crystals and circles out from the Crystal Palace. The Crystal Heart serves as a crown jewel of the empire; it's warming glow helps keep the city in perfect harmony.
Well, at least it did. Currently the city is under attack by the resurrected King Sombra. Princess Cadence is able to keep him at bay with her shield of love, but as the Crystal Heart is still missing, it is only a matter of time till she will fail. The fate of the Crystal Empire, and Equestria, is in the balance.
The Fun Has Been Doubled! is a My Little Pony: Friendship is Magic moderate-to-advanced forum roleplay. Set after the events of the fifth season, we currently have no overarching plot.

Canon characters and original characters are available for you to play as, both ponies and non-pony species alike! Just remember that we are account-per-character and we'll be fine!
