This heroic quest is part 12 of the Claymore Timeline. You must have completed the previous steps to begin this one.
Notes
This quest is marked as heroic but all mobs are solo mobs.
When you speak with Jabber Longwind, he talks about a war. Tell him that you hate the name of the war and that he should change it to: The Feathered Fray.
Steps
Use the Vultak Scavenger Site pad at ( -721, 144, -149 ) Copy/waypoint -721, 144, -149, to go to the spire at ( 483, 293, 537 ) Copy/waypoint 483, 293, 537 to The Barren Sky. Speak with Jabber Longwind who is standing next to teleporter spire in Barren Sky. Take the cloud to Whisperwind Isle and climb the cliffs up to the Elders. Talk to Graywind the Elder ( -677, 8, -509 ) Copy/waypoint -677, 8.4, -509.
Note: Even though the portal revamp lets you use any Ulteran Spire to get to Barren Sky, to update the quest you must use the one on Vultak Scavanging Site.
Now you need to kill the The Ghastly Overcast (level 66^) on Cloudmist Isle in the thick mist to update the quest, this spawns the Gentle Breeze. (If he is not up, you must wait for some time.) Talk to the Gentle Breeze to further update the quest.
Harvest blast-filled bedrock nodes for 20 quest updates (on Isle of Awakening)
Kill a crystalline burrower (level 65, solo mobs) for 5 quest updates (on Blackwind Isle - south east - around ( -491, 125, 439 ) Copy/waypoint -491, 125, 439 )
Return to Cloudmist Isle and talk to the Gentle Breeze again. If Gentle Breeze is not there, keep clearing the isle till Ghastly Overcast respawns, kill it and then Breeze will return.
