The Vials of Eternity

Seven vials were drawn from the Well of Eternity by Illidan. He poured three into the lake on top of Mount Hyjal and a second Well of Eternity was created. For years the rest were believed lost.$B$BWith the opening of the Dark Portal, we've come to know that he gave one each to his lieutenants Kael'thas and Vashj. Retrieve what remains of them; we will need them as foci to open a gateway to any events tied to Mount Hyjal, recent or ancient. The outcome of the Battle of Mount Hyjal must be preserved.
