@TheMinorFall I have no problem with Coodaudu (I assume you mean the demon and not the host, if Tsitua was in a car crash as a child) being absolutely ancient as long as owner guy is older. I sorta saw him as so-old-I-remember-only-vague-details kinda stuff anyhow. Owner guy would not have been active as a fighter in the Cold War era, but given your proposal...I could change that. I figured out why he does what he does. More loss, yay! His...I dunno if I'd call her a wife, but the lady he loves, she is a phoenix and a Seer. She is essentially comatose -- his doing, in part, because she was suffering, similar to Zeela. He thought death and rebirth would heal her, but it did not. So now she sleeps and he makes sure her dreams are predominantly pleasant. Unfortunately she also barely remembers him, and doesn't really notice his influence, but...well, it's really hard to kill a phoenix permanently, so it's the best he can do and he just has to live with the rest. Pretty sure part of the reason he doesn't act directly most of the time is because once when he did he made things worse. Possibly the time that got her hurt. He tends to encourage a bright path, but intervene directly only enough to allow those involved to have a choice. Helping Amune -- and maybe stopping Coodaudu -- would be so there is a choice in this era.
AND THIS IS WHY I LOVE WORKING WITH YOU!
By the way, isn't Jack the missing piece of Tsitua's soul? Coodaudu said he's sticking around only long enough for Tsitua to find his missing piece, so now I'm a wee bit confused.
