“To get you an artifact we'll need some temporal energy. Normally we use infinite cloaks woven from temporal threads, but those threads are frayed in this timeline. So instead I need you to gather those frayed temporal threads from around Dalaran. You can find them popping into and out of existence here and there. They look like radiant golden orbs of power, you can't miss them. Once you have enough of them bring them back to me.”
