Three Guardians are said to have defended humanity and the Traveler in their most dire hour. A Hunter, of flesh and blood, torn from his past into the future. A Titan, of metal and circuit, searching for her true purpose and identity. And a Warlock, born of both Light and Dark, eager to prove herself to her comrades. This is their legend.

Jarek-7 is an Exo Titan under the apprenticeship of Lord Saladin. The Iron Banner competitions have returned to the Tower, and Lord Saladin has brought Jarek with him. However, during his stay at the Tower, the Exo meets a very friendly Warlock named Tessica, or Tess as others call her. Jarek seems to have caught her eye, and now its up to her to try to soften his Iron Heart.
