Steppe by Steppe

Steps

 * 1) Askr sends you to search for the key to a tomb in Thundering Steppes.
 * 2) Search for tomb off the southern coast of Thundering Steppes. Take the griffin to Coldwind station.  The tomb is literally just off the beach at Coldwind Cove, underwater ( 386.32, -77.47, 1429.44 ).  You can use the griff tower as a landmark, head into the water and slightly right of it.  There are Rallosian ghosts around the tomb, but they don't seem to have any part of the quest.
 * 3) Search the bags around the tomb, clickies on the ground.
 * 4) Seek out the Unkempt Druids near Ruins of Karana ( -692.19, 12.05, 552.26 ). They're up on the rock wall.
 * 5) Speak to leader, get the key which is in one of the boxes on the ground near her. I'm assuming the targetable druids will be aggro if player is of the level for the quest.  They were grey to my L72 and didn't auto-aggro when I spoke to the leader.
 * 6) Head back to the tomb, open it up to get the shard.
 * 7) Return to Askr.
