Ooh fun prompt but also I have seven main characters BUT I will keep it short! Disclaimer, a lot of these names were chosen on a whim/I liked them when I first conceived the characters but over time they kinda grew into their names so...here we go!
Amethyst Nightingale - The Nightingale family is a noble family, aka they're known to breed incredibly strong magic users. Members of this family are named after minerals/gems because the Nightingales are specifically best known for their control over earth manipulation and construction
Ryn Atlas - Ryn was a name based on the existing japanese name Rin but I added a y to feel cool or something idk lol but it stuck. Atlas because the mythology of Atlas is the man who held up the sky and for story reasons...I'll just say Wink
Harrison Adams - I was thinking about Harrison Ford the actor when I was coming up with this character and due to their gruff personalities I decided to lean into it. Adams cause it has a nice ring to it
Qing Lo - The surname is a nod to my aunt whom I love very dearly. Qing because I've always liked the sound of it, plus how many Q names do you come across?
Perry Lenekov - Perry because...Phineas and Ferb...yes yes but honestly its not the only reference. Lenekov cause it rolls off the tongue for me
James Davis - I've always liked the name James and Davis is reference to an old friend of mine...but it's also a very generic white dude name and honestly? Go Off King, lean into it
Pablo Russo - Yeah you're gonna laugh but I named him after the penguin from the Backyardigans. I don't care. I love him. Russo cause I like it?
Anyways I feel like I got off track with this prompt lol
