General Bio:

Prince Major is the only son of Celestia and Sombra. Major hasn't been in Equestria for several hundred years, spending his time travelling and offering his military services in other countries and kingdoms. Major's talent is in Military Strategy, though due to Equestria being such a peaceful place, he had very little chance to use it.

Major isn't close with any of his relatives. He doesn't have any friends, but does find himself interested in Saturn Glow and Meadow Lark.
