Hey, Whinaut. I'd be up for something if your interested. Currently, all my topics are on pause so they're all free atm. However, as far as specific characters go, Michael and Zahara have not seen any (real) activity yet and Alexis just finished a topic so she's completely free.
For short, their all fighters by profesion:
Alexis is a gun nut and mercenary while Michael is the same but for swords. They move around for work so they can end up anywhere. Zahara is a desert bandit so she's more region specific.
Anyway, if any of these seem interesting for you, let me know.
