As mentioned in Calliope's bio, I was also going to write a bio for Sylvester, so here it is now.

Sylvester Seer is a witchling boy who also attends Hexside and is a part of the oracle coven track. He has fair skin, hot pink eyes and raspberry hair. He is typically seen with his cowl hood on, and he has purple sleeves and purple pants on under his uniform. His father is a harpy based on a martial eagle, so there are feathers on several parts of Sylvester's body. The edges of his sleeves are tied so they can be a little tighter. Unlike the Clamp sisters, who bring their own boots, Sylvester wears the boots that most students are seen wearing. His palisman is a rabbit named Cyril.

Sylvester is an awkward boy who, despite being pretty smart, is also timid. He gets scared, distracted, and upset pretty easily. He's also insecure, getting a bit panicky about some of the outcomes he sees. It's not the fortune telling that makes him this shot, though. Sylvester actually really likes being able to predict the future because it helps him know what to prepare for, therefore calming him down a little. Sylvester, despite his mood swings and fears, is still a nice guy and opens up pretty easily to people as long as they're friendly towards him.

Sylvester can do magic, and his coven track's magic lets him predict the future and look into crystal balls. He doesn't have his own crystal ball yet, so he borrows one of the school's. In addition to that, Sylvester likes to play card games, cook and smelt minerals to make jewelry, all three of those being his hobbies. He's also a bit good at math, so for those of you who suck at it, he's the one to see.

Sylvester is good friends with Calliope, a girl he met when she noticed he had a crush on her twin sister Lorraine. Calliope noticed that he did and offered to help him ask her to go with him. This ended with Lorraine and Sylvester getting together, and now the three of them often sit together at lunch. Sandar likes Calliope's friendly nature, as that's one of the best qualities a person could have in his opinion. He is a bit concerned about her constant drive to help others, though.

Sylvester is currently dating Lorraine, and the two have a pretty good relationship. At first, Sylvester thought that wasn't going to happen because Lorraine didn't seem open to being in one, but she did want to try it and see what it was like. She accepted his offer, and so far, she doesn't regret saying yes. They text each other often, and they also follow each other on Penstagram even though Sylvester isn't very active. Lorraine is very kind to Sylvester and enjoys thinking up ways to make him smile because she knows he's a little anxious. Before meeting Lorraine, Sylvester has actually had a crush on Boscha once, but it faded when he noticed how mean she was.

Sylvester is staying with his grandmother in a nice little house near the middle of Bonesborough; his parents are in the Emperor's Coven. Sometimes, at school, he felt stressed out by some of his schoolwork and unsafe from some of the freaky things he saw. He hoped that taking the oracle coven track would help him feel a little safer because he thought he'd be able to predict what would happen during the day. Once he was older, he started to crush on some of his female schoolmates, but they had pretty bad attitudes. Before he knew it, he was crushing again on an orange-haired girl from the construction coven track. He found himself liking her more than his previous interests, but he didn't get his hopes up. The girl's twin sister decided to help get him closer to her, and he found having her around enjoyable, so the two quickly hit it off. After he spoke to the girl, whose name was Lorraine, a few times, Sylvester built up the courage to ask her out. Lorraine didn't feel all that open to getting with someone, but at the very least, she wanted to give it a try. She accepted his offer, and over time, she grew to like him. The three of them are doing just fine now. Sylvester knew that it wasn't going to fix all of his problems, and he's still trying to fix them himself. He has been working on his social skills, and he considers that a start, but he also still occasionally gets stressed out from school and jumpy whenever something frightens him.

You know what happens now:
- Sylvester's parents call him often, but he's pretty worried about them.
- Sylvester has a couple of friends from the beast keeping coven track because he's a bit interested in what they do. His aunt Ollie is a beast keeper as well.
- Despite being a witch, his grandma, whose name is Nat, can't do magic. She had complications with her heart that led her to have to get the sac of magic bile attached to it removed.

- His parents are named Terrence and Vivianne. - Terrence is an eagle harpy because of eagles' keen eyesight.- He has thought about mixing his oracle magic with beast keeping, but he knew studying more than one kind of magic was against the rules. He hasn't been informed on what has been happening at the school lately yet.
- Sylvester and Lorraine have been dating for almost ten months now. They aren't comfortable with most nicknames, so they call each other "hon."
