After being left behind in the badlands after her expedition is attacked by a dangerous monster, Twilight Sparkle must survive a hostile, alien environment. Lucky for her, she has some help from one of the natives: A curious changeling named Thorax.
During Equestria's annual royal summit, newly-met Shining Armor and Pharynx discover they have a fair bit in common, including a passion for homeland security, and an extremely dorky little brother/sister.
Embracing the power to share love rather than steal it, the changelings work to reinvent themselves and their kingdom while Thorax seeks to introduce a more peaceful hive to Equestria.
Pharynx doesn't really like potted plants, but Princess Luna does. So what better way of getting him to stop ruining her lavender pots, if not with a good lesson or two?
They were actually making progress in the conversation department. “Hey, sunshine, you’re a genius, aren’t you? Leading an army and all that. Help me with this crossword.”
The changelings are no longer creatures of violence. They are no longer shady, private, hostile and fierce. They no longer are the acting steel hoof of Chrysalis' will. Time has changed them, and to Pharynx, it has changed them for the worse.
The Dragon Lord and King of the Changelings have been invited to the Royal Canterlot Gala. They're allowed to bring one extra creature, so they choose Garble and Pharynx. Those two should be able to get along, right?
Stories about monsters disguised as treasure chests were thought to be no more than legends. When Sunburst finds the last one in existence, the Changelings come to him with a demand: to kill it and send the species to extinction.
Despite their detached relationship, Thorax never gave up on his brother. With Pharynx now transformed, his cold demeanor has begun to thaw, and so Thorax is presented with something he's never had, before - an interactive big brother.
Under the light of the moon, King Thorax and Prince Pharynx come face to face with the changeling's grim past - a dark crown, and the beast that still wears it.
Hearth's Warming traditions are often the same for ponies and creatures as they are every year, but this year Tempest gets to experience something new and different. And she learns that changelings are used to new and different.
As the hive embraces a brighter future, so do the arid lands surrounding it. Caught in an acclimating climate, the hive now faces a series of downpours that limit both flight and activities. Luckily, Thorax has a plan, and a cozy one, at that.
Caught out as a traitor to the hive, Thorax tells a desperate lie: he's only been pretending to be the ponies' friend so that he can avenge his queen. Now he has to somehow make that lie seem true, and nothing will go according to plan when he tries.
A group of ponies accidentally activate a dormant alien spacecraft. Things only go downhill from there... Or uphill, depending on who you ask. | In Part II, the ponies attempt to befriend a resistance group opposing the evil Oblivion Empire.
An alternate reality requests the aid of the Elements of Harmony and the Princesses in fighting the greatest threat they may yet face. However, this threat goes by a name familiar to all of them: Thorax.
Pharynx thought he knew his life pretty well. Then, the barrier at the Canterlot Wedding banged against his head, restoring memories of a past life. He was a girl?!
When you're a lonely love vampire, you befriend baby dragons. It's what you do. When you're an alpha bugmoose who adopts an entire hive, you teach reformed parasites how to be cute and cuddly. It's what you do.
When Pharynx continuously has nightmares about his old outcast issues, he comes to face two options: to open up to his brother about his issues, or to continuously let himself crack under the constant pressure.
Pharynx won't ever accept these new Changeling customs. He won't ever accept the lovey-dovey ways of his peoples. Even on his death bed he won't ever sympathize for the Ponies like his people do. Maybe he'll tolerate, for the sake of Her.
The war against Equestria is failing. The Changelings are losing hope. Is there any hope for the tide of war to turn? Is there anyling to deliver hope?
