I loved Kai Opaka, I thought there was something very spiritual about the way she was portrayed by Camille Saviola. The Kai's Robes suited not only her figure but also her whole personality.
Which is why I was very sad in the Episode "Battle Lines" where she is taken from the DS9 'Verse to pursue her own "Pah" on that barren moon far away from her people.
But what makes me more sad, is that she was never checked up on by "The Sisko" or anyone else from Bajor. What happened to her? She must have been alive on that Moon throughout the entire Dominion War.
It's a mystery, that was never ever resolved to my satisfaction, and this is not just a loose end, it was a tear in the whole fabric of the DS9 story arcs.
A Light-Sale craft emerges from the Celestial Temple, containing Akorem Laan (Richard Libertini) - A Poet from 200-plus years in Bajor's past.
This person, claims to be The Emissary, and due to the regular twisting of Prophecy that occurs in this series, it actually looks like he MAY be the "real" Emissary.
So, Sisko steps down - Which immediately causes a bunch of problems- So it takes Kai Opaka to step in and make The Sisko think about what the hell he has done.
Maybe the writers of this 'sode were showing us, Opaka maybe had joined the Prophets and could appear to The Sisko like they do - But whether her appearance was really her, or the prophets, it took Kai Opaka to settle this mess! I'm SO sad they they never pursued Kai Opaka's ultimate "Pah" in DS9 - I liked her quite a bit, unlike that scumbag "Kai Rachet".
