I gonna be honest; I have no clue how old Rox is anymore. Originally they were seventeen- the age I was when I the year I made them. But with cementing and polishing of other character's backgrounds, Rox's age has kinda become a mystery...
ANYWAY- enjoy Rox ft. Beelzubeth and Beelze . . . Looks at list of Lord Fly names . . . Beelzeblip
Crazed logic and math below cut
TL;DR: Rox is 21, I guess?
the events of the canon timeline takes place in early spring of 2016. so Levi has just hit his 30's. he was born in early October but the exact year of his birth is hazy with his serve memory lose- but he forcefully adopt Rox as his sibling after he leaves Gelnbrooke, and Rox is still impressible but ultimately damaged (So Rox would have to be pre or early teens?)
The O'Dare Twins were born in June, 1990- making them 26 (But Levi met and looked out for Heather in Glenbrooke. Levi left before Heather and Heather escaped when she was 19 or 20 so let's say 2010)
Logan is a year younger being 25- her car accident happening in spring of her senior year of high school, 2008 (But Rox has to be an age that isn't too creepy as they somehow get involved in a queerplatonic poly relationship with Heath and Logan...?)
So lets say... Levi is five years older then Heath and Heather- making him 30 and born prolly in '85 then... he'd be 24 when Heather escaped Glenbrooke and he would have met Rox by that point
Idk, let's Rox was born in 1994, 9 younger then Levi, that would make them 21 at the start of the main timeline as Rox's birthday is in December.
There is this fucking MONSTER of a fly in my room right now and I don't have bug spray, just this 574 page vogue and I'm really really scared it's gonna bite me.
