There's a list of oc's I wish I could rp with, but it'd absolutely not fit in with my timeline

. Ionie
. Ryoto
. Kohaku
. Twilight
(Etc)

If I roleplayed with Ionie, I'd have to do one of two things.
1. Make it so none of my current ocs (except for Maralyn, Navaah, Victoria, and Twilight) were born, since she was alive billions and billions of years ago
2. Make it so she never died, but that'd change everything. Nothing would be the same, especially with Maralyn's character

That was an example
