Shen-zin Su is the ancient and gigantic sea turtle that the lands of the Wandering Isle sit upon. For 10,000 years he has made his way through the world's oceans, keeping away from the Alliance and Horde lands all this time. All pandaren on the Isle know of him, though no one has spoken to him in hundreds of years. This changes when the pandaren people sense something ill has befallen him. Finding the source of this ailment is the main thrust of the starting zone quests for the playable pandaren.
