Defense of Aviana
Assist Thisalee in the defense of the Shrine of Aviana in Hyjal, then return to her in the Dreamgrove.
Description
The situation is dire. The Legion is attacking the Shrine of Aviana in Hyjal, AGAIN! They must be after something specific, but I'm not sure what. Us Druids of the Talon are skilled scouts and infiltrators, but are lacking in... durability. They won't be able to hold out for long! We must go to help!

The following is information for obtaining Archdruid's Lunarwaing Form
Talon's Call will becomes available after you complete Strike Them Down and get the Breaching the Tomb achievement.
Once you return to Dreamgrove, pickup the quest Defense of Aviana where you will need to head over to Mount Hyjal.
Once at the Shrine of Aviana, go straight into the building and speak to Skylord Shadegrove. Complete the scenario by killing the mobs outside the Shrine and revealing the spy. Head back to Dreamgrove.
Once you are back in Dreamgrove, turn in Defense of Aviana and pickup You Can't Take the Sky from Me. Fly to the quest area in Azuna. Once there, you will be ported to the scenario. For me, this happened at 38.72,25.31.
Complete the scenario and kill Infazzar. Don't forget to look the Corrupted Idol of Aviana.
Return the Corrupted Idol of Aviana in Dreamgrove and collect your new flight form.
