Carissa has been occasionally departing the demiplane for cult encouragement. Her cult is... encouraging, she guesses, not for any purpose for which she'd actually want to leverage it except accounting for her activities and adding to her hoard of souls. It's certainly very vigorous and enthusiastic, in those cities where it lucked into good local leadership or a resonant bit of theology. The pamphlets she releases routinely with her teachings are widely reproduced and/or strictly banned in forty-six countries.
Aside from that she has chased down a few of the threads on her wall, mostly to unsatisfying conclusions. No one knows what Aroden's aims with the Starstone protections were. No one who is allowed to tell her knows at what stage in ascension those who go missing and can't be resurrected are destroyed. The Church of Abadar, which provides Starstone attempt insurance (full price of a True Resurrection plus fees, up front), knows how often it happens, and it's not often, but the ones who it happened to seem like those who were more promising than average, not less so.
No one knows much about the universe Pharasma came from. No one knows much about the overall composition by planet of origin of any of the afterlives other than Axis. Mortals aren't allowed to wander around arbitrary parts of Axis either. She's put up hundreds of scraps that will, perhaps, assemble into an answer when she's smarter. Such and such apparent species observable in Aktun. Such and such results from Fe-Anar's analysis of the linguistic inputs to various languages spoken there. Such and such results on supposedly random summons. Reality has consistent features deep down; you just have to be positioned to notice them. She's no longer in the habit of thinking of it as an ilani teaching, rather than a Sevarite one, but it's important.
When she's tired of that she works on Keltham's magic adder. It's complicated the way problems are supposed to be complicated, instead of the way they turn out to often actually be complicated.
