It sounds as though sinister dealings are afoot: “The Beacon that looms over Stormreach’s Harbor is known as the Emperor. For as long as humanoids have lived there, the Emperor has stood, and the beacon it holds has shone brightly both night and day. Meanwhile, a faction of the Cult of the Dragon Below plots.”
In addition to the new quests, Update 38 has made significant adjustments (read: buffs) to the Artificer and Druid classes. Players will find that dual-wielding weapons are going to function better while moving, meet new Eyelet companions, and just about a billion other things. Seriously, read the patch notes if you play, because this update has a ton of stuff to absorb.
