As per the poll, here are maps for Chapter 1 of Baldur's Gate Descent into Avernus.
As usual, all the maps are roll20 ready if you own the module. You simply need to drag and drop.
Inside the zip drive you will find day and night versions of all relevant maps in Baldur's Gate as well as an additional map of the city gates, a random street, and the Sword Coast path for the encounter on the way to Candlekeep.
Also, you might notice, I figured out how to size the maps so that no black border is needed (like with the candlekeep) maps for them to fit with the dynamic lighting lines in Roll20. I should be able to do this with all maps going forward.
I hope that you and your players enjoy!
