The Final Battle is Here. 
When Arthur found a magic sword in a pawnshop, he never thought it would make him into the Builder of Legend and thrust him into the forefront of the fight with the Darkness. 
Now, on a mission only he can complete, Arthur and his girls will have to hold the lines against the Darkness's final assault while defeating the four horsemen, freeing God from captivity, and of course, confronting the Empress. 
Sure, the odds might be stacked against him, but if there's anyone who can do it, it's the penniless orphan turned King of Heaven and Hell.
