Mythological guises of Selenim across the secret history?

In many Indo-European cultures, there are ancient myths of dueling groups of deities. The Aesir and Jotun in Norse myth, the Tuatha de Danann and Fomorians in Irish myth, the Asuras and Devas in Vedic myth, the Ahuras and Divs of Persian myth, etc.

As confirmed in the quasi-official past life for ancient Ireland, and in the French, the Fomorians of Irish myth were Selenim (as well as a Hydrim metamorphosis inspired by them in Chronicle of the Awakenings). So it stands to reason these others groups of opposing deities were based on the occult conflicts between Nephilim and Selenim. The Jotuns aka Ettins, the Fomorians, the Asuras, Divs, etc. Even the Titans, Giants and Daemons of Greco-Roman myth, or else involving themselves in socially accepted witch cults, mortuary cults, and cults that practiced human sacrifice.

When dealing with past life eras that involve these kinds of dueling pantheons, then Selenim players have the option of selecting that as the identity of their Selenim PC during that incarnation era. I need to devise robust rules for Selenim past lives, but for now assume they work largely the same as Nephilim (i.e. gaining skills based on their guise during that era, see Ian's CC notes). 

Most Selenim don't incarnate in new bodies due to being ageless and lacking the appropriate Spell, but that doesn't mean they continuous live through the intervening centuries and continually gain points in Skills, Emotional Traits and Aspects. While they don't usually enter Stasis by physically dying, the weight of the years usually forces them into a depression that mimics Stasis. The form of Stasis taken varies depending on the character: some retreat psychologically and run on auto-pilot for decades or centuries at a time, some retreat to a Black Moon world in the lower planes (perhaps their Realm if they have one, that of a friendly Sovereign, or a lawless nightmare realm), and a rare few retreat to a hidden sarcophagus.

The official and unofficial past lives are Nephilim-centric and don't give options for Selenim PCs, but you can justify a Selenim PC being active during any incarnation period.
