Depending on how old Halflings can become, we could also meet Chaotic Good https://scryfall.com/card/clb/55/alora-merry-thief again after about 100 years. Or she has a special explanation like Minsc and Volo why she is still alive after 100 years in exactly the same time and region...
Nooooooo!!! Alora ties with Quayle for me as BG1 companion I most dislike. I’m more than happy never to have to encounter her again.

I have also theorised that Viconia might be the person who sent Shadowheart for the artefact. And I wonder whether Edwin might be connected to the Lorroakan plot. I’d be happy with either or both, and would no doubt enjoy cameos from almost any other BG1/2 companions still likely to be alive and in the area, but don’t particularly want them to be party members. I’d rather have new characters for the bulk of my BG3 gang.
Edwin was human, so are you thinking he is a Lich at this point or just used magic to extend his life as Wizards do? Do you think he has taken over Lorroakan's tower and is manipulating events from there?
