From the developer:
Explore the vast world of Arkesia. Choose from diverse advanced classes to customize your fighting style as you battle demon legions, colossal bosses, and more in your search for The Ark.
For 500 years Arkesia and its people have enjoyed peace. They have forgotten the war between gods and demons that tore their world apart. They forgot that all of the light was once stolen, and darkness threatened to overcome all.
