Magadore

Magadore was a powerful wizard who drained the life out of Cantha's forests, converting it into energy around 572 AE. When Zojun had led an army of Rangers and tamed animals to Magadore's lair, the lair collapsed on top of Magadore by the weight from the army's number. Upon his death, the life Magadore stole rose up out of the ground and returned to the forests, which instantly flourished once again.
