Go to the Caverns of Time in Tanaris and gain access to the Battle of Mount Hyjal. Once inside, defeat Rage Winterchill and bring the Time-Phased Phylactery to Akama in Shadowmoon Valley.
Now Warmane-gold shares with you The Warmane Black Temple: An Artifact From the Past. When you are hesitating exactly where to buy Warmane Gold, Warmane-gold is going to be a superb selection.
Part of this quest happens in Shadowmoon Valley and Hyjal Summit.
Illidan’s attention is now on Kael’thas, thanks to you. The time has come to make our move.
I’ve had a vision of an artifact that will aid us in our final struggle – the phylactery of a lich known as Winterchill. Unfortunately, its power was lost forever after his defeat in the Battle of Mount Hyjal.
There might be a way to retrieve this artifact, however. Legend speaks of a place in Azeroth guarded by bronze dragons… a place where past and present meet. It is there you will find what we seek.
Have you retrieved the phylactery yet, <name>?
My vision… it all becomes clear now. The powers this artifact has over a soul…. to contain it… to siphon it into itself… I will use those powers to reclaim what belongs to me! The time has arrived for us to take the fight to Illidan!
Upon completion of this quest you will gain:
2.500 reputation with Ashtongue Deathsworn(The Ashtongue Deathsworn are Broken Draenei under the command of the Elder Sage Akama. Akama was believed to be a servitor of Illidan Stormrage, but may not be as loyal to the Lord of Outland as originally thought…)
