One more thing. Regarding Shiva in the FF series and why it is so different from the Hindu Shiva. Apparently the katakana used in FFIII were supposed to be read as "Shiver" but FFIV put it as Shiva and it's been kept ever since.

Also, more info on Glasya Labolas, referred to as the president (or earl) of hell, the author and captain of bloodshed and slaughter, tells all things past and future, knows all sciences, gains the love of all who know him, can incite homicide and make people invisible. Appears as a dog with griffin wings.
