At the beginning of all things, following the titanic struggle between the three progenitor wyrms, the dragon Khyber, bound in the depths of the world, spat forth the fiends and demons, who ruled the world for millions of years.

1.5 million years ago, with the help of the couatls, the dragons rose from their primitive state and began to revolt against their demonic overlords. This war raged for over a million years.

100,000 years ago, the couatls sacrificed most of their race to send the most powerful of the demonic overlords and fiends back down to Khyber, to be trapped for eternity.
