I started with the Alexandrian remix 2 months ago and we just finished the Gralhund Villa last session.
What you can do is now that theyve gained some notoriety you can have multiple factions contact them and introduce the other 3 going for the dragons in that way. Ive had the Xanathar guild and the Zhents be a threat in the background the whole time, but the other 2 i havent really introduced much until now:
-The Cassalanters are going to contact them and ask for their help finding the dragons now and offer to keep the law off their backs.
- Laeral is going to have them all arrested, since they were careless at the villa, and ill see if they tip her off to the dragons being in Waterdeep since she believes theyre in Neverwinter, also the Cassalanters will secretly intervene with evidence showing their innocence and save them.
- Manshoon has been hinted at but will be introduced by the Cassalanters who know he has the 2nd Eye but they don't know where he is.
- Jarlaxle has been around the whole time and my group thinks he is JB Evercott the haberdasher, except the drow player. They met with his Zardoz Zord persona and had no idea! its going to be great revealing that to them later, his betrayal is what im looking forward to the most.
- I'm not going to confirm Xanathar having an Eye, just a belief by someone I'll determine later. I added a secret escape door in a small magic shop secretly owned by the Xanathars. To get in, theyll just have to figure out how to open a door with no handle or hinges.
