When Valery told Evan about the dreams she often had, she described a long-eared man with black hair beating down a little girl.
According to her, at the end of the fight, the man used a powerful ability called 'Sever' through a blurry-looking weapon whose appearance she couldn't clearly see.
Although the weapon was blurry as if it was shrouded in a black fog, it still gave her a terrifying feeling as if she was looking at something far above her level.
Upon hearing that the man used a weapon that gave her such a terrifying feeling, Evan immediately thought of the Halberd of Destruction.
The first time he saw the World Tree after entering the closed World of Dryads, Evan had unlocked a memory related to the Universal Tree.
In that memory, Azroth used a blurry weapon whose appearance he couldn't clearly see to destroy the entire Universal Tree.
