Question that's slightly unrelated to this. How does it work, when certain souls return to the Hells after they're killed? Imps, cambions, you name it. Would Karlach burning up and dying be at risk of just ending up serving Zariel in the "afterworld" or whatever one would like to even call it? Given she's basically tapped herself out from Avernus and up onto the Material Plane, with Zariel's prototype toy.
