You know how during the part in the game where Sin destroyed that village and Yuna had to send all of the dead to the farplane? Lulu tells Tidus that if the dead aren't sent to the Farplane they come back as fiends. Well tell me this, when Auron mentions he died at the hands of Yunalesca he was never sent to the Farplane so he was able to return. How did he still keep his human form? Also how did Seymour also not become a fiend after dying in the Temple?
