Character ages!

Rawne's is something I've basically invented. He has no canon age, but for convenience sake I've pinned him at a decade younger than Gaunt

that means he's 32 or so at the beginning of the series and 42 during Only in Death, which is where his current canon point is for TLV

Cheradenine actually says his age as 220/110/30 in a flashback chapter that I'm pretty sure is about a decade before the present, so he's 230/120/30 now

born 230 years ago, lived 120 of them, looks about 30
