The Forever Trees are special trees highly revered by the Kurzicks and found in the Eternal Grove. During The Eternal Grove mission, players defend the grove and the trees against a Luxon assault.
The Forever Trees have special magical powers. Through some complicated process, Kurzick volunteers are transformed into Kurzick Juggernauts at these trees and given immortality. As long as a Forever Tree lives, the Juggernaut tied to it will never die, even if destroyed in battle, the Juggernaut will simply resurrect at its tree.
The Forever Trees are activated through a ritual performed by Kurzick Tree Singers called the Songs of Arboretum.
