I'm going to ramble about my SW OCs for a bit, since @zeawesomebirdie said he was interested!
So, when I say Star Wars OCs, I actually have 4: Cehim Velm, who's a Pau'an mapmaker, and the three Jedi, Korcha Serach who's a Harch, Reil Zilarrest who is human and Devafe Ardolald who's an Arkanian (to give you an idea of what they look like, here are drawings of them I've done before: Cehim here, Korcha here and the padawans there). Korcha was Reil and Devafe's master, and she's very much based on a japanese teacher I had in school whom I respect a lot, whereas her Padawans and Cehim aren't really based on anyone besides some aspects of me. Here's two timelines I have on hand, the first one is just the Jedi and the second one is kind of a quick sequels chronology with important dates, characters, and their ages at said dates, for comparison.
Which is what I'll use to start on Reil: you'll notice he 'dies' in -19 BBY, because technically if we follow the events of canon, he absolutely would not have survived Order 66, as opposed to the other two who might have, I still have to decide (though of course in my head everything is fine everyone is happy and they all live to be very old) The reason is Reil is a crèchemaster, and well, we know what happened to the younglings.
Reil loves working with the kids, loves seeing them grow and learn, the way they're young but creative and clever and kind. Korcha also likes younglings, but more for what they represent than anything else: she's very respectful of traditions, and seeing the new generation of Jedi, with their little tabards, learning the thousand-year-old traditions, always makes her feel warm. She's more suited to one-on-one instruction, though, and she doesn't particularly want to take care of a group of 15 children for too long. Devafe is the only one who didn't inherit the youngling-loving genes, if you will, because she isn't a fan of kids running everywhere and being active and noisy, she likes her calm too much. The only ones she appreciates are the quiet ones who come to the Archives to read, because they have that love of books in common.
In general, Devafe is more drawn towards mental, intellectual things, whereas Reil is a very physical person. She loves sitting down and reading, writing essays, meditating, and Korcha had to push a little for her to put as much effort into the more physical aspects of training. Reil is the opposite, he prefers tangible things, activities where you can clearly feel what you're doing, and even if learning lightsaber combat was harder for him because he's visually impaired, he preferred spending an afternoon going through katas again than being stuck listening to a recording of a book he has to read (because, headcanon time: I imagine they have audiobooks in a galaxy far far away, but the really interesting texts Padawans get assigned as readings don't necessarily have a recording, and if that was the case he had to listen to Korcha or one of his friends read him the book, which can get old quick. In any case, he wasn't a fan) Devafe's hobbies obviously include reading, but she also likes playing board games, and she has an interest in geography, while Reil is more the type to have plants, to do pottery or to paint.
Korcha is is a strict Master: she wants her Padawans to do the best they can, to really invest themselves and to be serious about learning. She gave them help if they needed it, she went over things they hadn't understood and explained them again, but they couldn't just vaguely do it to say it's done. She had to get better at helping, because she tended to assume people weren't cooperating when they just didn't understand or didn't know how to go about it, but the Padawan isn't the only one learning things during the apprenticeship haha. While she’s strict, she will never pass up an occasion to sing the praises of her Padawans to someone else, and she’s very family-oriented, in a way: she regularly hosts little get-togethers with her extended lineage and friends where people bring food and have a chat, and when she sees all the people she loves in the same room having fun together it warms her heart. She also puts a lot of importance in traditions, she respects them a lot, she's very proud of contributing to the Order, and of helping it grow and prosper by training new Jedi.
This, by the way, is why both Reil and Devafe had the silly Padawan haircut: I personally headcanon it's an old tradition and Masters are free to ask it of their Padawans or not. Obviously, Mrs Traditions Are Important had them wear it, and let me tell you they both were glad to grow it out, though not really in the same way. Reil, though he's let his hair grow when he became a Knight and hasn't cut it since, kind of liked the clear, tangible reminder that he was someone's apprentice, that he belonged with the Order. Devafe was less enthusiastic and mostly thought it was ugly, I imagine she was pretty happy the serious Master Serach wanted her to be her Padawan, but when she had to cut her hair short like that she felt a bit disappointed.
Korcha, given that she's based on a language teacher of mine, is kind of specialised in languages. I haven't thought of all the languages she studied, but she speaks quite a few of them, and can do a good translation job. Devafe somewhat followed in her footsteps, but focussed on only one or two, and really got familiar with the culture's litterature and culture. Reil wasn't as interested, and while he picked up a few things it's not really one of his skills.
I imagine Devafe as the kind to want to specialize in Makashi, if that helps get a better reading of her vibes, while Reil is probably better at Shii-Cho or Niman, and Korcha remains to be decided. After a little research, I determined that Reil probably has an acceptable level in lightsaber combat, given that he can't really see much. I think it would make sense for him to use a shoto, or at least one of those adjustable-length sabers, because the closer you are to the person you're fighting the better it is when you don't see them. His level certainly wouldn't be good enough to send him on missions that would involve combat or, later on, to battles in the war, especially if you add his disability, but he prefers staying at the Temple and teaching the younglings in any case. He would win against someone who isn't really trained in combat and doesn't know him, but that's about it. However, he was trained, knighted and lives in an era where there's no actual need to be excellent at combat: there are no Sith anymore, and lightsaber combat is mostly a sport. It's understandable he wouldn't be incredible at it, and it's not a skill he absolutely needs, so overall it's fine. As for Devafe, she didn't particularly want to spend hours sparring, but she likes being good at things, and she couldn't just let herself be acceptable at it: she wanted to have a good level if only to have a good level, and she put effort into it (that, and Korcha wouldn't have let her slack off anyway)
I haven't mentioned it yet, but she's also a very honest person, who will say what she thinks if she says anything. That and the fact she applied herself to be good at as many things she could meant she was totally the type to say things like 'oh, it's fine, you weren't very likely to win' after a spar with another Padawan, not because she's mean or she thinks she's inherently better like people assume she is based on the fact she's Arkanian, but because that's true: she spent time practicing and they didn't, that's the logical conclusion. Korcha, who was the same kind of kid except she did think she was a little better than others and had to learn humility, has to remind her to avoid saying that kind of thing, and that honesty isn't always the best course of action even if it's true.
Finally, I wanted to give them sort of a lineage theme: Korcha’s master was a Bothan who saw this little spider girl who acted like she was cooler than everyone else and that other Jedi didn’t particularly want to take on and made her their Padawan; Korcha did the same for a blind boy Masters didn’t know how to train and an Arkanian kid with a reputation for being too full of herself. Not that I’m saying Jedi are prejudiced and assholes, not at all, just that sometimes you don’t think you’d do a good job at teaching that specific kid for whatever reasons. And that’s a good thing, if you don’t think you would work well with one of the Initiates then don’t take them as your Padawan, that’s better for everyone involved! But Korcha’s Master and Korcha herself thought they could do it and they did.
So here, that was for my three Jedi, I love them very much and they’re cool <3 I actually have maybe a few more things on them and I didn’t talk about Cehim but honestly that’s enough of a novel for tonight haha
