Sephiroth is a fun reference, it beats Angra Mainyu (Zoroastrian evil spirit) in FFX-2 but they called another monster Ahriman (another name for Angra Mainyu) so they lose points there.
Um, yes. Sorry, I think the mythological references cropping up in things (like FF) are amusing. Some are well thought out (like the Sephiroth, the ten emanations of God/tree of life in the Kabbalah) others are not (like Angra Mainyu/Ahriman). ^_^;;;;
