I have a party of 4 level 3 adventurers from a currently running D&D 5e campaign (Forgotten Realms but very sandboxy homebrew pirate adventures - they are all pirates or related professions e.g. smuggler, bounty hunter).
I'm planning to let them fall into one or more of three published Wizards of the Coast (WotC) adventures:
- Curse of Strahd
- Out of the Abyss (OotA)
- Princes of the Apocalypse (PotA)
Are there any potential links between these adventures defined in the published adventures themselves, or otherwise officially defined by WotC, that I can use to keep the segue feeling sandboxy and open to player agency? (I'd prefer links that make sense in-game.)
I remember at least an explicit mention at some point in PotA there are tunnels from one or more of the temple areas into the Underdark, so there's a lead-in for OotA. What about Strahd? Can e.g. the Mists appear deep underground while you are trawling through the Wyrmwrithings?! :-)
Has anyone made a convenient table of potential but explicit links like this between all the public WotC adventures?
