I feel like it's easier to write characters you have at least some kind of common ground with, so generally I think there's a little bit of me in all of them, and no single character I can point to and go "yeah, this one is me."
Rekki definitely looks the most like me, so a lot of people who don't know me too well might think she'd be the one who represents me in the story. She's a short white lady with a similar sort of build to me, her natural haircolour (pre-magical empowerment) is close to mine, and like me she's got intense expressions and big bodylanguage and is short-tempered. She's also prone to selfishness and wants to be important and for people to admire her. I feel like in a lot of ways, she's like a lot of my worst traits turned up to eleven! She's a lot braver and tougher than me though, and much more straightforward.
Sarin is in many ways a lot more like me than Rekki. She's one of those people who gave off "teacher vibes" even as a teenager, like me, she takes everything very seriously and she tends to be much better at executing a plan than improvising. She's intensely proud and a bit prickly, and rather moralistic and come across self-righteous to some people; traits we definitely share. She's also really, really, really gay and full of lesbian yearning for all those cool ladies. My partner tends to say that Sarin is really more like me than Rekki is, and they're probably right.
Subo is the character who's the least like me, because I wanted him to be like this... really relaxed guy who is personable, sociable and chill, and who doesn't really pay much attention to politics, while I'm kind of a weird and intensely anxious person with zero chill and very political. We do share a love of small comforts though. Like me, Subo doesn't really care about having a big fancy house or car, he just wants to chill and have a nice drink in a comfortable environment. I don't think I'm like Subo, but I'd like to be friends with him!
Jules, who we'll see a lot more of this chapter. is definitely in the running for character who's most like me, because she's the character who inherited my sense of humour and she's also autistic. She makes a lot of jokes to cover for her anxiety and discomfort in social situations, tends to ramble, over-analyse situations and come up with solutions that make sense though her logic but make everyone else go "ummmm.... why didn't you use this way simpler, more obvious solution?" Of course... she's also a cool goth and a lot less forthright about what she's thinking than me!
