Azyreil, the god of life, and Zashtiel, the goddess of death. These two characters never make a direct appearance in The Legend of Istavia, although Zashtiel goes by another term when mentioned by the Lunadrel.
I've written a shortish supplement to The Legend of Istavia called The Fall of Nezachim. It's meant to be read after Istavia, but if you're the type who likes to read prequels first, that's fine too.
The Fall of Nezachim is about the beginning of the world. It tells of Nezachim's birth and how he became the evil god you meet in Istavia. You can read it (for free!) on the book's official website: http://thelegendofistavia.blogspot.com/p/the-fall-of-nezachim.html
