I haven't written in a while and I realized that I haven't talked about how the leoren and the rest of the intelligent animal species came from, so here we go.
Where They Come From
Thousands of years ago, there were only two intelligent species in the world, dragons and elves*. For a long time they lived in peace, but eventually a rift in the elven community started a war between the elves of the north and the elves of the south.
In those days, the elves had powerful magics that were later lost, which allowed them to create armies to fight their war for them. They imbued elven attributes, like bipedal walking, speech, and hands capable of using tools, to the animals of the land to create soldiers, laborers to supply those soldiers, and servants to care for their own needs and wants.
The elves of the south used big cats, so the ones in the north used wolves, the ones in the south used buffalo, so the ones in the north used bears, etc. By the time the war was done, there were a dozen or so new species in the world. They eventually left the elves' service and founded their own kingdoms.
* as far as they realized, but that's a story for another time, as well as the story of where the dragons and elves came from
