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.

"To be a ship's medic is to be doctor, priest, teacher, and parent to your crewmates. You're the one who's supposed to fix everything, the one they scream for in agony, the only one upon whose shoulder it is permissible to cry. They willingly bare their souls to you. And that sacred trust is how I endure." Karin Chakwas reflects on her time aboard the Normandy.
