Yeah, it's what I suggested few pages ago. An Avernus dlc would be awesome, with Karlach's questline being a side mission and it can trigger only if you bring her along with you.
I'd honestly love to see Zariel. I've read a lot of interesting things about her in the forgotten realms lore. And since we've seen the gods of other companions (Vlaakith, Shar, Mystra), would be sweet if Zariel was added in the list.
well we see the other big problem people from other companions. Astarion has cazador and you go to kill him so it'd make sense to put zariel in to add much needed content to karlach as well as bring her up to the same level as the other companions. also if you choose minthara you see her god as well kinda.
