Heya!
Did you catch that NPC, Alfgar, talking near The Quicksand?
He was like "Don't listen to what they say!" and by they I mean the few fellows known as Arcanists that are showing up near the camps of Ul'dah giving message of an imminent catastrophe.
Seems like he wants to bring comfort to the people in Ul'dah by saying that they are imposters or something like that.
