Kabr, the Legionless

"I have destroyed myself to do this. They have taken my Ghost. They are in my blood and brain. But now there is hope. [...] Now it is done. If I speak again, I am not Kabr."

- Kabr

Kabr, the Legionless was a Titan who became obsessed with the Vault of Glass.

The Great Ahamkara Hunt
"The driving bass line of a classic song from Old Earth drove their prey before them. No less than a half-dozen wyverns snarled and clawed at the trio as they stabbed and blasted their way through the wilds of Mars. Praedyth wished hard. Wished it would never end. Alongside him, Kabr was a towering giant. An Awoken-made weapon roared in his hands and in his head."

Along with many other Guardians, Kabr and his fireteam - the Warlock Praedyth and the legendary Hunter Pahanin - participated in the Great Ahamkara Hunt.

The Vault of Glass
Kabr attempted to raid the Vault of Glass with his fireteam, but they found themselves unable to get past the Templar and its oracles. Kabr crafted for himself a set of armor from the bodies of fallen Vex, which began to affect his mind and gradually assimilate his body. Before the end, Kabr's last words were recorded by Pahanin, who described Kabr as "a good man." It appears that everyone from his fireteam, except for Praedyth and Pahanin, was erased from existence by the Oracles, and that not even Kabr himself could identify who his teammates were; he explains, "No one can open the vault alone. I opened the vault. There was no one with me but I was not alone." In the end, when his team was lost and his Ghost was taken from him, Kabr was determined to not die in vain by forging his light into The Aegis, a shield of incredible power that could change fate itself and defeat the enemies of the Vault.

Years after the original fall of the Vault of Glass, an intercepted transmission from the Vex Collective claiming to be Kabr's consciousness was discovered; said transmission stated that it had uncovered the true nature of the Vex's perception on Light and Darkness, seeing them as basic threats to survival rather than true enemies. It is unknown whether this is truly Kabr speaking, in defiance of his last words, or merely a Vex simulation of his memories and personality.
