Saint-14

Saint-14 was an Exo Titan best known for his crusade against the Fallen. His crusade led him to Solkis, Kell of the House of Devils, whom he killed 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. He was later sent by the Speaker to investigate what Osiris was doing on Mercury. 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.
