Quicksilver

Quicksilver is a Thunderlands-Windlands mixed horse and a member of Midnight's Apprentice group.

Physical Description
Quicksilver is 16 hands high and has a build similar to a quarter horse. Though he has no wings, his coloration is like that of a pegasus-- white, with silver hair and hooves. He has blue eyes, and a distinctive silver lightning bolt stretching from his shoulder to his flank.

In the Norm, he appears as a light dappled gray.

Personality
Quicksilver is an optimistic, carefree, fun-loving horse who tends to brighten the room with his personality. His energy is boundless and he likes to run around aimlessly when he has nothing better to do. He is more athletic than studious. He can be a bit of a show off.

He has a serious side, however, especially when it comes to his family. He was found alone in Silvertail as a foal and brought to the EWI, where he was raised. The only remnant of his parents that he retained was a book of poetry by Skye, with a note inside written to a pegasus named Argenta. It remained a sensitive and somewhat confusing subject for Quicksilver until he unexpectedly met his sister in the Thunderlands.

Midnight, Indigo, and Dawn
Quicksilver's loyalty and enthusiasm makes him a good friend to have, though sometimes he isn't aware of other people's needs. He considers Midnight his best friend. He doesn't have a particularly close relationship with Indigo, because they have contrasting personalities. Sometimes Quicksilver talks to Dawn when he needs to discuss his feelings, always warning her never to tell anyone about it.

Chestnut
Quicksilver has had a crush on (or a "breeze" with) Chestnut for a while. They banter frequently. Chestnut tends to call Quicksilver out on his immaturity and laziness, but they have a mutual affection for each other.

Graye
It didn't take long for Quicksilver to become very protective of his sister Graye. He tries to support her the best he can and get her to work through her insecurities. His confidence helps her feel better about herself.
