The Shielders battle a war that has been raging for centuries against Starkorfs, who harvest humans and Shielders alike to obtain a near immortality. Alongside the charming Lucas and selfless Paul, Karla must unravel the purpose of her curse and battle an unknown presence manipulating her thoughts; a mysterious woman who may be dormant for now, but has every intention of possessing Karla - mind, body, and soul.

Within this new reality that Karla faces, the search for the Three Immortal Blades begins.
