Surprise, here's a post with some solid OCs! Mobs are more of a "species" than a character since they're not an individual, but these two are characters of my own. Meet Zach and Lea, two roommates living in a mediocre flat in a city somewhere. I'll be giving each their own post, but decided to make this one first to give some worldbuilding. They're adult humans living together as roomies, both chipping in on rent and expenses.

Zach is frazzled and often obsessive over a series of unexplained missing persons cases in the area, losing sleep while scrambling over posters, connecting dots, trying to piece together the puzzle. He even has one of those conspiracy boards. In his spare time he watches true crime shows.
Lea, however, seems largely indifferent, and prefers to be slovenly and languid- she seems to go out to buffets often and gains dozens of pounds overnight, around when people go missing. Perhaps she's just stress eating, thinking about all those poor lost people? That's surely what she means by them having an "impact on her diet."

More to come of these two, and possibly some worldbuilding on their setting. I have other stuff in mind.
