The good news is that the River District was cleaned up as players were dealing with the events of the prior expansion, but the bad news is that players will be interrupted in the middle of a ceremony in the now much-less-spellplague-filled district. It seems that a wizard named Gyrion claims to be the rightful ruler of Neverwinter, sparking an intra-city civil war in the middle of the district that players will have to unravel through the Cloaked Ascendancy update. So now you know why you’ll be there! Other than the loot thing.
