Val'sharah is an ancient forest on the Broken Isles where druidism was first born. Malfurion Stormrage learned to become a druid here under the guidance of Cenarius prior to the War of the Ancients. It is also the home of a World Tree, Shaladrassil. Around the time of the Burning Legion's third invasion of Azeroth, Shaladrassil was corrupted by the Emerald Nightmare, which also proceeded to corrupt much of Val'sharah, its central and southern portion being the only parts uncorrupted. Xavius leads the Nightmare forces.
Val'sharah is one of the leveling zones in World of Warcraft: Legion.
