Eclipsa, despite being a unicorn, has always struggled with magic, and all throughout school never got the help she needed. Twilight, one of the four princesses and her very own neighbor in Ponyville, tried enrolling her into the School of Friendship- hoping that befriending others would help Eclipsa unearth the magic she possesses. However, that didn't last long. With the unicorn's crippling anxiety, the whole "making friends" thing was a huge bust. Twilight knew what it was like, however, and suggested a more personal approach. Typically, Princess Celestia only takes on students when they are young (and helps them throughout their young adult lives), but when Twilight vouches for Eclipsa, the sun princess is rather... intrigued. And so, Celestia agrees to take on Eclipsa as a personal student. However, when the two start to converse outside of their lessons together through letters, things start to get...a little personal.
