ough that would be, a lot. Are we talking about just main protags or are we counting the protag's friends and stuff?
Main protags I've got:
Zeo,
Drake,
Sven,
Will,
Dio,
Symon,
Arvariene,
Cyen,
Shiode,
Elmin,
Node,
Hero Who,
Blank,
Aric,
and Ren.

Sven, Will, Dio, Symon, Arvariene, Cyen, and Shiode all share a universe, and so do Zeo and Drake, but most of the other characters are in their own universes.

Obviously that doesn't list characters like Cherente or Maggie, because they're not main protags/pov characters in their stories, but if I listed all the other characters, we would be here all day. There is definitely more than 100 characters I have knocking around in my brain
