Argonian Daggerfall

In the year 2701 A.D, the first contact with an Alien race called the Umdali was recorded. They came to earth looking to recruit human beings as an allied in the everlasting fight against the World Devourers known as the Argonians.

Come follow Sly as he does his part in the neverending struggle between the two factions using the Umdali's E.F.S (Evolutionary Fighting System)
