So many ways they could go in the D&D Universe. Forgotten Realms Avatar trilogy. Ravenloft would be a great story line too. The Ice Windale trilogy to open up the rest of Faerun

I would love to see the Avatar trilogy from Forgotten Realms be made into a weekly series. From there you could go so many ways. Icewind trilogy. Or even some Harper’s standalone shows. Always wanted DragonLance and Ravenloft as well
