Welcome to the comm! I hope you'll eventually feel comfortable enough to post your fanwork here--we're pretty laid-back, and if you'd rather not get any kind of crit, you can just say so.

can Dragoons really settle down and get pregnant? And did any of them do it?

I think this was addressed in the fifth supplementary novel, and I want to say "no" on both counts but it's been so long since I read it that I am not entirely confident. So unfortunately, I will have to come back to this sometime after NaNo. XD;

Trying to figure out the 'proper' spelling of Zefiris's name (Zepheris, Zefiris, Zeferis, Zephiris?)

Zeffiris. Full name Arffi M4 IPD. Dragoon Zeffiris. (And no, I don't remember what IPD. stands for either. orz) I've actually listed the official spellings for all the Dragoons here.

. . . sorry for being especially useless right now.
