Hello! If the PCs let the Cassalanters be damned to the Hells in Dragonheist, when, where and in which form would it be best for them to appear in Avernus? They could appear at any time! If you want them to be favored of Asmodeus, they could appear as greater devils with a “gift” from their benefactor. If they disappointed Asmodeus, then they could be a couple of squabbling minor devils blaming each other for their misfortune. Fun!
