Zabetta, Santos, Scorpio, Greg, and Vera are my oldest Maritonia characters. The comic was originally about all of them. The earliest iterations of the comic were a gag a day about a band that were also wizards. There was a whole gang of characters including a talking scorpion (who was a real asshole). I know we'll see one of the other OG OCs in chapter 6, but I haven't found a place for some of the others.
The Pi-rates and Sulphur Tongue were created a couple years after these guys. Smith and Brad are probably by newest characters. I didn't flesh them out until I did chapter 2. Miriam's boyfriend was only mentioned in chapter 1 and at the time I didn't even give him a name because he wasn't ever supposed to show up again. Smith was going to be a character in the future but I was writing a Miriam spin-off comic and that's when he became a fully formed character (which was like 2022?).
