Osiris
Osiris is one of the most renowned Warlocks in the history of the Last City and its former Vanguard Commander, known as the Warden of the Infinite Forest.
Biography
Osiris's relentless study of the Vex and the Darkness led to his exile from the Last City, after which he devoted himself to the Infinite Forest on Mercury. He is the close companion and partner of Saint-14, and was once the teacher of Ikora Rey, who defended him before the Vanguard.
For years Osiris was accompanied by his Ghost, Sagira. He built the Sundial on Mercury to reach back through time and save Saint-14 from death. He later lost Sagira during Season of the Hunt, and with her his connection to the Light.
Unknown to the City, Savathûn secretly took Osiris's place for roughly a year while holding the true Osiris captive — a deception uncovered during The Witch Queen. Now without his Light, Osiris has continued to advise Guardians, and he aided them in mastering Strand on Neomuna.
Location
He was introduced in the Curse of Osiris, but began appearing outside of cutscenes starting from the Season of Dawn.
The Sundial Spire — a special location on Mercury. It is impossible to reach the Sundial while being in the Mercury patrol zone, the player had to load into the Sundial Spire activity.
