Neriak Destrier Whistle

The quests start in T'Vatar's post with Laexyra Y'Barriath. You need to follow her series that will eventually send you to Wanderlust Fair. You may have to do a couple of extra quests around here until Gaussnitra V'Kilana starts offering you quests. Follow her series until you are sent to Vicaonar's camp just outside Wanderlust Fair. Do all of his quests to open up Larnexa's series then follow hers back to Wanderlust Fair. Malyl will then send you to Atalika in Shadow Oak and this is who will finally award you the mount after you have completed her tasks, including the task that requires you to speak with Madam Victra who will grant the quest "Collecting the Spirits".
