Dragons playable as Rider's Dragon.
Humans (vary varied. Can be a Northen snowdweller, southener, rebel, anything)
Gran'zul (idk if I remember the name right. Basically Urgals from Eragon books. Very big guys, males have potruding fangs. A bit orcish in appearance. Usually live in villages but they have a settlement that can almost be called a town. They have horns. Are warlike but aren't necessarily evil. They still love their family and fight for their freefom and evetything)
Narven(reptilians, live mostly to the south. Many live together with the southern people near the desert, they are agile and varied in colour and shape. A bit like humans.)
Elves (Immortal in the sense that they cant die of natural reasons. They can get old though. The are very fast and strong compared to humans, and all of them know how to use magic. Their hair and eyes can be many colours, no ginger hair though, but their skin is always fair)
Dwarves (live in the massive mountains to the south, they have 9 clans which specialize in different fields and each has a leader. They have a king that rules over all clan leaders. Their biggest cities are underground but have some above ground as well.

Thats kinda it I guess. You can add monsters like sea serpents and krakens and huge desert worms and mega man eating yetis for action though.
