Divine Source

The Divine Source is an artifact of mysterious origins, but is known to grant immortality along with a myriad of supernatural powers. Jacob and the Remnants believe that the Divine Source holds a fragment of the soul of God and believe that is the reason why the Divine Source is able to give immortality. The Source was hidden away in the legendary city of Kitezh where the Deathless Ones, immortal soldiers who swore to guard the Divine Source, stood guard against anyone that may use the Source for evil purposes.

In Rise of the Tomb Raider, the plot revolves around the Divine Source and the special ability of granting immortality. First hinted at by Lord Croft, Lara Croft and the mysterious organization known as Trinity compete against one another to take control of the Divine Source.
