5) Crossover with some other game, setting, novel etc. I know I'd be surprised if IDK we meet the nameless one in Avernus, fight One-of-Many as an optional boss working for Myrkul or bump into Liriel Baenre or something. There's a lot that Larian *could* do here. Mercer's involvement makes me wonder if there's going to be some CR stuff in the game, or alternatively some mtg-related stuff since WoTC did a tie-in with the game.
If that should be true with MtG, then "Planeswalking" immediately comes to my mind. That would fit (Mordenkainen). It could even be a good justification for why we see Volo again... I believe that Larian could also justify side trips to or visitors from Rivellon. I just realize that I wouldn't necessarily like it.... Too many universes... In the end you hit the wrong universe and the Orcs are running around with machine guns.
