Yggdrasil

Yggdrasil is the oldest tree on Ryu 108, although some of the redwoods are larger. Planted there almost 35,000 years before Book 1 by Brahma, this tree was grown from a cutting of a blue spruce tree that Brahma took from Heaven's Arcane Garden to the Physical Realm. The tree is located on a small island outside the city of Bjornholm, and this entire island is considered holy ground by all of Ryu 108's peoples. Like most of the rest of the Scions of Heaven, Yggdrasil's roots once housed a portal to the Nether Realm that has since been closed. However, despite the portal being gone, the roots of Yggdrasil hold the entrance to Nastrond, a vast underground cave system at the bottom of which which Arkaroo slumbers.
