Ellitrea will go over everything for them. She realizes this is bizarre and probably really terrifying if you're hearing about it now - after Altarrin's death - and not, like Altarrin did, smashing Carissa's spells with raw mage-energy and badly injuring her in the process (because she wasn't expecting their Gifts any more than they were expecting wizardry), keeping her unconscious with Healing while he did a frantic research project on the god-names they'd glimpsed in her thoughts, determining something was odd and waking her up under enough compulsions that she couldn't finish thoughts -
She had considering praying to a god, for help or just answers. Not Asmodeus, though. Uhhhhh. Possibly they would have to ask - Carissa - about the other gods, but there are some that Altarrin even sort of agreed might not be terrible. There's one dedicated to fighting Evil and Asmodeus in particular, maybe? ...This was a really long time ago and she has mostly not been the one reading Carissa's mind since. Ketar's done it more, including after the point when (Ellitrea is pretty sure) Altarrin and Carissa went off to a secure location that was not anywhere near Iftel and had a heart-to-heart, and Altarrin arranged to give Carissa a set of incentives where she could best achieve what she wanted here, working for him.
...Carissa's world doesn't have Foresight anymore. For some reason that Ellitrea does not entirely understand but possibly involves gods being murder-able? Carissa did not, uh, know the details. She would presumably have to be vastly more powerful anyway to murder gods.
Carissa was deeply indignant about most of the local gods, which she considered bizarrely unhelpful and incapable of communication, and also outrageously against, you know, progress and magical advancement and material wealth and all children learning to read.
Ketar had a crush on Carissa which she worried would be a problem but with some firm advice (including from Merda) she thinks he got over it. He was probably mostly worried about Carissa being mistreated by Altarrin. Carissa had some much worse relationships in Cheliax, which is, you know, unsurprising, country ruled by a torture god and everything.
She...will admit that Carissa's arrival was - probably implicated in Altarrin's death, in a purely causal way, it's not a coincidence that the gods made a much more involved attempt on him within six weeks of Carissa's arrival. Partly the spellsilver mine, of course, and Altarrin being - willing to take a greater risk, because the upside of Carissa solving the Empire's problems was worth it to him, but also... Uh, she can't remember when they had this conversation, but he thinks the gods dislike Foresight noise. Carissa, as an out of context problem, is noisy. Altarrin wants to use her out-of-context abilities to push back further against the stupid awful gods than they've ever managed before. Presumably the gods disapprove. It's - not Carissa's fault, that Altarrin is - the person he is, somehow the gods already disliked. But she'll acknowledge the - relation.
(She thinks Carissa was sad. Not devastated, she - tried hard not to get attached - but sad, and angry at Velgarth's gods for destroying so much. She didn't actually read her mind, though, it was just body language and - knowing her as a person.)
She'll maybe dig up a few bits and pieces like that but she's running low on new information and also the ability to have coherent thoughts. It's nearly dawn.
