The vastayashai'rei protected its most important landmark: the God-Willow, a massive tree, dripping with long gossamer leaves that shimmered with golden-green light. During ancient times, a battle between the groves protectors and Freljordian warriors ended with the God-Willow's destruction. The whimpers of countless beasts, the bawling of rivers, the howling of trees and the dripping tears of moss, they lamented the God-Willow's death in a symphony of mourning. Centuries have passed and at the place where the God-Willow once stood, a being known as the Green Father emerged with a clear mission and purpose: to protect all life and teach the world's people to respect and appreciate all that is. Omikayalan's sapling is guarded by a group of secretive Vastaya lords.
One of the oldest magical trees in Ionia, it was destroyed centuries ago by Ivern the Cruel, who absorbed its power and became the Green-Father. Eventually a 3sapling would rise from the dead trunks of the God-Willow, which is protected by a spirit god known as 6Sai'nen Thousand-Tailed and a group of vastaya.
