Until recently, the Instant Adventure daily quest was given by the NPC in the back of the Manufactory. The one that gives the Chronicle, Raid Rift and Expert Rift dailies. Standing right next to him is the NPC that gives the T1 Raid dailies.
Now for some inexplicable reason, the IA daily is given by some random NPC all the way on the other side of Meridian, nowhere near any other daily quest givers. What's the story?
