Two fillies, a pegasus and a unicorn, move into Ponyville when Aura Sparkstar, younger sister of Celestia and Luna, and older sister of Crystle Diamonds, starts to get strange headaches from time to time. Galaxy, the older filly and unicorn sister of Milkyway, says it should go away soon. Milkyway is the younger sister, and is a pegasus with a flowing, starry mane.
But nopony knows where they lived before they moved. Galaxy keeps scribbling into a red notebook with a tree on the cover, but the tree isn't a regular tree. Oh, no. Not a magic tree.
This tree has silver leaves.
And what is she writing?
Where are they from?
Why are they hiding it?
Who are they?
Why am I asking these questions?

Oh, and now re-rated Teen, for pony-swears and out-of-nowhere pony-butt whooping. Yep..
....Oh, and when they open the watches, their height grows to about teenagers. Truly, Galaxy is around 300 and Milkyway is around 200.
~ Story is based off of a roleplay that me and my friend started after I made an OC.
