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 some ritual performed by Kurzick Tree Singers.
