Getting There Before the Coalition

Steps

 * 1) Now that it is clear what Lucretia Nasin's purpose is, Chiara has requested, on behalf of the Ironforge Exchange, to retrieve what the Coalition is after before they get to it. I should search within The Crucible for items related to Miragul's ability to teleport through time, space, and dimensions.
 * 2) *Pick up the tome at in the a Reflection of Silence.
 * 3) *Click on glowing spacial disturbances throughout the zone.
 * 4) *Kill and loot the residual powder that proves Miragul has crossed through the very dimensions themselves. (A grey encounter will not drop the required update.)

Rewards

 * At least
