I think we've definitely got all the people for the ablution set up- it was mostly around the people Caster knew and would contact.

However, because it's Kairi, it could lead into future conversation about the huge burst of darkness/blight/corruption because, I mean, it's literally that Judar is a bit of a generator for that. Like, drawing in and turning the energy (which he could send back out.) I don't think we had a chance to really play with the princess of light/fallen magi (or dark/cursed/corrupted wizard of creation) kind of thing. Especially with how he's turned into a huge downward spiral since then.
