This page states: "Enuo was imprisoned inside a great tree inside the Great Forest of Moore, while the Void itself...", and then: "500 years later, the tree used to seal Enuo had itself become a being of great evil power, Exdeath."
Exdeath's page states: "A common misconception is that Exdeath is the reincarnation of Enuo. However, it is untrue and has never been proven with direct evidence."
Likewise, Enuo's page states: "A common misconception is that Enuo was sealed in the tree that later became Exdeath, though this has never been proven with evidence."I haven't played Final Fantasy V, and am no expert on it, so I don't want to edit this article myself in case I have missed something. But it does seem like there is a certain conflict of information here.
Enuo and Exdeath are completely different entities. Enuo was an evil warlock whose soul was sealed on a tree at Moore, along with other nasties. Over a thousand years, that tree became corrupted and became Exdeath.Exdeath literally is a tree. A tree which has Enuo sealed, one might say.
