Trey was originally going to be an alien, but I decided to make him an elf instead because the story I had planned for him was badly written and also really problematic.

Trey is an elf with sky blue skin, reddish-violet eyes and very long blackish-purple hair that's tied into a low, bushy ponytail. He wears a golden rope-like headband on his head. His outfit is a magenta pink costume that shows the sides of his torso. There's a light pink pendant that has a yellow star in it close to his neck. He can detach it from his costume at any time to do his magic. He also has yellow bands on his forearms and a yellow belt. On his feet, he wears golden yellow sandals. He made his costume himself.

Trey is a very mischievous and playful boy. He runs wildly and freely, and he can be anywhere at any time. There's no restraining him; he'll go wherever he wants to go. Because of his popularity throughout his village, he's proven to be quite a charismatic guy. He doesn't always know where he's going, and he'll trip and fall on something if he's not careful. He would much rather add some pizazz to something he's doing rather than follow the instructions. If there's one thing Trey really, really loves, it's jewels. He has a whole collection of them. He also likes to drink hot drinks such as scepter's burst and hot chocolate, even when it's very hot outside. 

Imogen eventually befriends Trey, and I like to imagine that she later on becomes his girlfriend. She found herself drawn to him, and heavily enamored by him, when he started helping her with her magic. Trey thinks Imogen is actually very cute, but he's clumsy and bad at expressing his feelings towards her. 

Trey is a magician much like Imogen. He hails from Charm Valley, a wide, mystical gully with a cloud of mist that hangs around it. In one of its many villages, he lives in a geode-like house with his mothers, Estara and Luna. He grew up intermingling with the people and scenery of his village. When he wasn't chatting with the humanoids and elves and charming his way into their hearts, so to speak, he'd be out digging around for jewels and other shiny things to add to his growing collection. Trey loved to goof around and do whatever he felt like doing in the moment, and he became known for his silly unpredictable manner. He'd also try to help them out and be there for them whenever they needed a hand. Soon, the people of Trey's village began to call him their Dearest Friend. When Trey turned 14, he received his magical tool, his pendant, at his Wand Ceremony. Out of the ten types of magic present in Charm Valley, he's still trying to find out which ones suit him best, exploring with them all. He eventually meets Imogen and some of her friends when they go on a trip there. 

His home is a rock on the outside, but it's very sparkly and made of jewels on the inside. All of his furniture and appliances are sparkly as well, and his collection of jewels is displayed on his dresser. His bed is elevated like the top half of a bunk bed. There is a pile of musical instruments that make up his one-man band beneath it. It looks like something you'd see in the Crystal Empire (I used to watch MLP when I was 10-11, so that's how I know about it).

Trey's voice is feminine as his headcanon voice is Princess Bubblegum. Another thing to know about him is that he pronounces the sound of the letter B like the sound of P, and he's never been able to pronounce the B sound.
