For the not tumblr people where’s some age musing:
I’ve posted about this before but I’m being lazy and I’m not gonna find the post just paste the text from my document >:)
(so I guess Hypothesis and Catalyst are bonuses here. cause they sure ain’t ROs)
"Dion is in his mid-late twenties. Mal’s a year older than him. Wil’s in the 25-29 range. Teddie and Kay are early twenties, roughly 22-24.
Alistair I could put as anywhere between mid twenties and early thirties.
Funnily enough, I wrote about CG’s age just yesterday, meaning I can say that textually, MC estimates she’s about their age, maybe even a bit younger.
MC also describes Hypothesis as ‘perhaps in his fifties’. Catalyst is late twenties to mid thirties.
(I have musings on pretty much the entire rest of the cast too, but I figured you were mostly asking about the core characters 
)
fiiiine twist my arm.
Arcade’s the baby of the cast. He’s like 21-22.
Vantage is in her early 30s. Enfilade’s slightly older.
Surpass is roughly 27-28.
Portrait is 24 days older than Surpass.
Lullaby is in their 30s. Gremlink’s in her mid twenties.
Rocket’s younger than you’d probably expect.
Alice is about the same age as Dion.
Mr. White is in his 40s.
Rico is about 23-25.
