Finally, is there any connection between Siberys and the Silver Flame? The latter seems too embedded in the material plane The Silver Flame IS embedded in the material plane. It was created by the sacrifice of the couatl, who are native celestials.

Mythologically the couatl are said to have been created by Siberys so there's a sort of connection there; it's ultimately energy of Siberys.
