Thanks for taking the time to write this! Domia is not currently what I consider a "loose end": she has some additional content, even if it's a little slim. She repeatedly doesn't score very high with supporting patrons, so unless I find a brilliant piece of story I want to tell through her, she will probably not be encountered again in this incarnation of Vae Victis - Khan.
There are, however, two "loose ends": Char and Shani, which I hope to flesh out more in version 0.14 but unfortunately I can't guarantee, the focus will be on the royal family for obvious reasons. Still, I hate leaving loose ends, so keep them fingers crossed!
