Irontree Woods lies in northern Felwood. Once a peaceful forest glade, it has been corrupted like the rest of Felwood by the demonic presence of the Burning Legion. Three Ancients (Hastat, Stoma and Vartrus), the great living trees of the night elves, have been petrified and remain permanently entombed within the Irontree Woods. Crazed treants, twisted bog beasts, ferocious wildlife, and corrupted water elementals also roam the woods, attacking any who venture near. This is also the place where you can start (or finish) the hunter level 60 epic quest.
