An ancient evil known as the Darkness that Dwells has resurfaced in America. A group of heroes in Japan known as the Elemental Sabers fought them before Ragnarok. Recently, one of the Sabers, Saber Antimony, has been seen leading a team of base raiders.
Information on the Darkness is minimal and Antimony may be the world’s only remaining expert. Someone wants to pay to find out what she knows but others want to find her for their own reasons.
