Saint-14

Saint-14 was an Exo Titan best known for his crusade against the Fallen. Reportedly, he killed a Kell by caving in its head with his own. Saint-14 was the owner of the Helm of Saint-14. Saint-14 vouched for Osiris' elevation to the commander of the Vanguard, believing him to be a pragmatic warrior. Saint-14 had theorized that the Darkness was an army of aliens that had been rejected by the Traveler; this was true at least for the Fallen.
