Vaharmane is a Dark Nature forest of the Emeldimir Vale. In the God Era, this vale and its forests served as a testing ground for the interaction of nature energy with its anti-thesis, dark nature energy. Under the direction of the CPD, a division of the Covenant, they studied the side effects of the ongoing Demon Spawn War (8972 GE - 9493 GE). One of these was the merging of nature energy with unholy energy, forming areas of invisible dark nature energy that lived by consuming its opposite. The studies concluded that in the right balance, the two energies could exist together.
In the Lith-Crillion Era, while Erassil to the northwest was being drained of its nature energy, Vaharmane became the refuge of many of Erassil's fey. Some of these were fallen fey, beings now powered by dark nature energy instead of nature energy.
Today, some of the forest's more dangerous natives are fallen dryads. Some skilled necromancers, they along with an orcwart named Var'lotrius are credited with creating the first undead treant.
