I just realized, that in the last three DRGIII novels concerning DS9 (RBoE, PoN, RtD), we never saw Opaka. I can't help but wonder now if something happened to her during the entire Ascendents situation...
I also wondered why Opaka wasn't in the last 2 ds9 books maybe we'll find out what happened to her in the next Ds9 novel coming out next year.
Opaka has made it clear that she considers her new spiritual path to lie outside the realm of politics or anything high-profile, so the fact that's she slipped off the radar doesn't necessarily mean something awful's happened to her. Maybe she's off meditating in a secluded monastery, or helping refugees in the wider Federation?
I found it mildly strange that she didn't show up at Vaughn's bedside, considering they appeared to be on their way to a relationship in Fragments and Omens. .
