elleani will join soon, the last dialogue with her (and the yarra face) leave no doubt. she will take the non combat slot before iris. if she join the harem don't take any role in the givini leadership. [and that slot must be one filled by a girl we meet before iris, but after wynn).
the IK's power over his seed is to clear a solution for neranda, and with the right research something can be done for the whole dwarren population, for sure eustrin don't will fall in aram's hand.
sarai will join the harem after the religous conflict will escalate to unsustainable level. the new chosen can or cannot be involved.
for the stenai princess, i think will join the harem, the DK is dismissive and delegatory, simon is his front face now. i think she will join simon, and after some time the other will tell her the true.
for fehliel, can be or can be not. i don't have strong opinion, and for esthera her death will be a sad, sad thing.
