Yawning Portal* (Dead in Thay)
1486
(Yawning Portal/DDAL Season 6 is a collection of 7 previous editions adventures, rewritten for 5th edition) - As technically only Dead in Thay takes place in the FR, there isn't any timelines on these - they are just dungeon/adventures, with no over-arching storyline. Dead in Thay takes place directly after Scourge of the Sword coast (which starts in 1485 DR), so would most likely be 1486 DR.)
