Saint-14 is an Exo Titan, veteran of the Battle of Six Fronts, and former Vanguard Commander. After an excursion into the Infinite Forest in pursuit of his partner, Osiris, Saint would become lost, and eventually killed by the Vex. This was only possible upon the creation of Agioktis, the Martyr Mind, which was capable of draining Saint's Light. After he fell, the Vex rather unusually enshrined his body amidst the scrap pile of the thousands of Vex he had killed.
Many years later, with the help of Osiris and his Sundial device, the Guardian was able to enter the Infinite Forest and save Saint-14 before he died, finally reuniting the pair. Upon his return to the city, Saint would take charge of the Trials of Osiris, a position he holds to this day.
Saint is also well known for his helmet, the Helm of Saint-14, which has been worn by many Titans after him.
