Lienia was born in a Pony Colony in Cervidas to a Pegasus couple, as a unicorn oddly enough. After being sent away to Equestira when a war broke between twin heirs, losing her parents, and spending five years in Cantorlot, she has settled in Ponyville. About ten years later, Twilight Sparkle has come and moved into the Library, become friends with her adoptive sister Rarity, her friends Fluttershy and Applejack, and her acquaintances Pinkie Pie and Rainbow Dash, Lienia's peaceful little home village has been turned into a sort of hotspot for strange occurrences ever since Nightmare Moon had returned and was defeated to save Princess Luna. then, about three -maybe four- years later, Fira shows up.
Fira was born with three sisters, Windwalker, Waterfall, and Shadowfax, as elemental Alicorns. She controls Fire, while her sisters control Wind, Water and Shadows respectively. Now, thousands of winters since they were born, Windwalker, Waterfall, and Shadowfax have been acting strange, and have claimed the names Windstorm, Monsoon, and Nightstorm. Every move Fira makes to try and keep up with her duties of her element of fire--burning the overgrown brush in the forests to help the trees grow more, only to have Windstorm fan the flames into destroying the entire forest, lightening fires to help warm herds of deer and various other animals trying to survive the cold winter only to have Monsoon either freeze the fire or drown it thus causing the animals to freeze, and lastly she tried to lead animals to safety at night using a flame at the tip of her horn, and Nightstorm surrounds her and her horn with such thick darkness that the animals can no longer see it and are lead astray to death.
When these two meet, Fira is fighting with her sisters, all resembling Nightmare Moon in appearance. Lienia dismisses this and comes to try and stop the argument, believing it is just a small dispute, only to be sent flying into a tree and encouraging Fira to defeat her sisters, then to banish them into the elements they control. Then after taking Lienia to Zecora's, where the unicorn wakes up.
When a year passes, the sisters will be free, but meanwhile Fira has to blend in with the ordinary ponies of Ponyville, and something begins to bloom between the two very different ponies. Will the alicorn's secret be kept safe until she has to fight her sisters again? Or will Twilight discover and inform the princesses of the elemental's presence and put them in more danger? And what's this strange riddle in one of Twilight's books about there is no harmony without peace?
