Osiris

"Oryx-Dead-King. Oryx Dead King, 3 words, 9 word bursts over and over. Osiris?"

- Master Rahool

Osiris is an old Warlock and former Vanguard who was exiled from the City.

Biography
A veteran of Six Fronts, Osiris was a well respected warrior whose prowess at that battle convinced Saint-14 to recommend him to the Speaker as Vanguard Commander. He had also served as the Speaker's apprentice for a time. However, his desire for truth about the purpose of Guardians and the nature of Darkness drove him to madness. His theories were not only considered borderline blasphemous, but he was also diverting Guardians and resources away from protecting the City and refugees, and towards chasing legends and rumors, such as the Vault of Glass; it's implied that he was the one who inspired Kabr, the Legionless into going into the Vault. He studied the Hive, in particular prophesying the coming of Oryx, and is also rumored to have come "too close to understanding the Vex".

His obsession with the nature of the Darkness and misuse of resources eventually drove the Speaker to exile him after the Battle of Twilight Gap, as the Speaker believed he had become as obsessed with the Vex as Toland, the Shattered had with the Hive. He is described as having a cult of personality, and has a number of disciples, such as Brother Vance, who attempt to see how far the Light can be bent before it can be broken. Osiris himself seems to have vanished, even from those who follow him, some claiming that he is at once "alive and dead."

Whether before or after his banishment, Osiris held council with the other two powers of the Solar System, the Queen of the Reef and The Nine. His arrangments with the Queen extend to his followers, explaining their presence in the Vestian Outpost.

The Disciples of Osiris hold a Crucible tournament in Osiris's honor called the Trials of Osiris, where they seek to recruit the toughest Guardians to their cause.

Trivia
