SPOILERS FOR BALDURS GATE 1 COMPUTER GAME
I said I’d have ago at a plot linking BG1 and Descent into Avernus. I think what I like about this is the opportunity to have characters from the first half keep popping up in Avernus. I’d be making the campaign a much higher level when they official campaign starts so it would need some serious re-writing, including the PCs taking the lead on Elturel defense - rather than just hiding in the ruins. And making Avernus a sandbox with more factions. While they are there, I’d definitely want a trip to some other layers of hell like Dis and Cania. Possibly triggered by plots from the BG1 section.
Anyway... here goes...
Prologue : Candlekeep (Level 1)
Explore your home, meet some NPCs, complete some tasks. Avoid two assassination attempts. Set out for the sword coast with the party’s mentor, Gorion.
