So my Galaxy Dust is starting to take center stage in my profile and I think I'm okay with that?

Sooo, I just realized that I never told you guys about Galaxy's character XD
"Galaxy Dust is a pessimistic pony. He's rarely seen in Equestria, as he rarely leaves his home deep within the Everfree Forest. Galaxy spends most of his time brooding and reading his large library over and over again.
Galaxy became the way he is thanks to his past. Once, many years ago, Galaxy Dust was an alicorn, a powerful pony in a high position. However, thanks to his sudden turnaround and lost his leadership abilities, resulting in him losing his horn. He gave up his chances of regaining his position, instead banishing himself from Equestria."

after Galaxy's character arc is over, he regains his magic and slowly grows his horn back. Despite taking up his old duties again, he wasn't satisfied with his life. Instead, he decides to become a tutor in magic and responsibility. His first pupil is a unicorn who goes by the name of Nebula Splash, somepony who's caused lots of problems with her magic. This is their first time meeting.

Ugh I feel like I can't get Galaxy right.... Making a Celestia base into Galaxy is hard x-x
