Oberon Greenhaze was once a hero to the elves who travelled the land slaying evil, yet one day he would return and lose his taste for battle - even when dwarven invaders came to the Evernight Forest he did nothing and fell into a mystical slumber.Over time a great tree grew over Oberon and gave birth to the elf's darkest dreams, corrupting Evernight Forest and transforming it into a nightmare - although far from heroic the Overlord would prove to be the one who would put an end to this by killing Oberon.During the fight it is revealed that Oberon has fused with the tree itself, becoming a horrific monster - driven mad by his centuries of nightmares he brings to life his nightmares: despite all this the elf is still slain in the end.
