A conundrum
I do love and appreciate the TF fandom for how cavalier it is about OCs but I also genuinely love so much of the existing cast so much that any story that is set during the war, I will inevitably end up staffing with characters whose relationship to the war I'm familiar with and also want an excuse to keep alive.
So a lot of my OCs will either exist exclusively before the war, created to be killed off, or exist post-war, and have their relationship to it also be in the past because canon already has me stuffed full, y'know?
(Also this post was bought to you by me waking up like "it would be Really Fucking Funny to make Velocity a Metrotitanfucker" and I can't stop thinking about how funny that would be.)
