I like the 'Avorn get sidelined' idea, or having someone NPC her. We don't need to spend the month in downtime boinking each other, either - if we can come up with a collective sideplot idea that everyone likes, we can get up to interesting shenanigans while we wait around. Between two/three Eldar, a Space Marine, two humans, and an abhuman (and Carli, if she's still here), we're bound to have something interesting happen.
