Gaurds are quite loyal to the princesses. The princess of the Night guides the gaurds when they're blinded in the dark night. The Celstial princess lights when they are troubled. The princesses' best gaurd is known as Sombra. He was loyal and powerful, but things went downhill. He was told to protect, when he kil.led causing to be driven. Sombra thought the best way to keep death from happening was to watch ponies 24/7. He heard of a city far nirth known as the Crystal Empire. He thought by talking over would show peace. (if by peace i mean kil.l a queen and s.lave all of her subjects). Celstia felt said that one of her greastest loyalist turned dark. So she had no choice but banished him to the ice. Then one-thousand years later she forgot about him and kil.led him. :D
