We are all fellow locks here, share coords and locations, locations, locations! I have swam the entire distance around the eastern continent. If you swim around where Quelthalas should be, its all just water and mountains surrounded by completely flat terrain. There is also a rumored GM island north west of teldrassil. To get to it, apparently youd need to have swim potions, life potions, be a durid aquatic and not be afraid to swim your tail

off.
