The Nine created sentient species and brought new ones during the wars. It's not sure if any of them survived but the magic they used during the wars opened portals to other dimensions and universes, through these new races arrived. New higher-beings appeared who also formed new creatures to fight for them.
Now from the viewpoint of Humans of late these races can be divided into two groups: Aquirs and Draquirs. Supposedly Draquirs are just a sub-group of Aquirs who have wings, and they are in fact - surprise, surprise - Dragons! The difference between them according to the successor races (the elvenoids: this is the equal of anthropoid on Ynev) that the Dragons aren't evil but Aquirs are very very much.
So these races built new civilization and fought among themselves. These wars were fought in the sky among the branches of the Auld-Tree, the Aquirs used clever flying machines and built their cities in the skies. Everything was drenched in magic and these creatures themselves magical beings.
The earliest appearance of Elves can be placed somewhere in the late First Era. Their god was Urria, who might appear in this age but also they believe that Urria is the Auld-Tree as well. Nevertheless they committed some sin which made Urria butthurt and turned away from them. Noteworthy that the Elves of the "present" aren't the entirely same Elves as the past, and they call their most illustrious individuals Auld-Elves, so it's possible the first Elves on Ynev was Auld-Elves. Still they were like children compared to the Aquirs.
As the closing accord for this Era the Auld-Tree caught on fire and burnt through millenias. Not sure when it was torn down, probably during the next age.
