There are other races, but only three will be playable (humans being one of them).

The first of the non-human races are the dvergr, which are this world's answer to dwarves. They are an endangered race forced from their underground citadels by volcanic activity, with stone-like skin.

The second are the heksvar - humans who sold their humanity to a witch. They are tall, gangly and lithe, with pale hues of blue for skin and an immunity to the cold.

Very brief. I can elaborate more if you'd like?
