Praedyth

"You think of time as a constant companion. Right up until you are drowning in it. Suffused in time, shivering under the glare of the conflux. Then you will know what I know. Time is a predator. And it cannot be sated."

- File 34543 from Praedyth's Ghost

Praedyth was a Warlock who had been part of Kabr's fireteam during their assault on the Vault of Glass. Praedyth himself was believed to be a myth; Praedyth's Timepiece and Praedyth's Revenge were the only pieces of evidence of his existence until the Vanguard discovered a message coming from the Vault.

His fate is explored in the Story Mission Paradox. After fighting through Taken, the Guardian discovers Praedyth's corpse, long dead, trapped deep within the Vault of Glass. However there is evidence that in another timeline or reality or even in an isolated space Praedyth lives.

If a secret area in the Paradox mission is triggered as the Daily Heroic, it is revealed that Praedyth still exists across alternate time streams, and that he originally worked for the Future War Cult using a custom made Ghost shell, known to players as the Intrusion Shell. His spirit implies that he was one of the first Guardians to discover Oryx's power to Take through what would eventually become his transcendent powers, as she (his Ghost) claims she saw the Darkness "wear a Fallen Captain like clothes," implying that it was Taken.

Trapped in the Vault
Praedyth, seemingly imprisoned by the Vex, tried his best to evade them and survive, which he managed while frequently creating messages in hopes someone would receive them. In these messages he detailed who he was, and his journey with Pahanin and Kabr, claiming The Vault had taken it's toll on them, with Pahanin talking to himself, and Kabr becoming "intense at time." While in The Vault, he took notice of The Taken approaching the heart of The Vault to take control of the Vex's Collective, who the Guardian later thwarts in a story mission. His time in The Vault ended when he heard the Vex "Closing the door." After this, he tragically cries out claiming he lived, and was a real person within The Vault, already understanding his fate. He was erased from the timeline, (presumably by The Gorgons,) and warped to be, as we learn from Ikora, a myth and a mere footnote in history books.

An Uncertain Fate
Several centuries later, Praedtyh's messages escaped The Vault, and reached the Vanguard. Ikora sends the Guardian on a mission to The Vault to stop the Taken detailed in Praedyth's messages. While in The Vault, the Guardian tracks the signal from the messages to find a skeleton with a faint signature of Light. This is assumed to be Praedyth, however considering the nature of The Vault of Glass, it is possible Praedyth is kept within his own dimension created by the Vex, or inhabits different timelines, giving the Warlock a bit of hope.
