I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life, freely.
Revelation 21:6 is a verse from the Christian Bible. It is mentioned several times by James, the Lone Wanderer's father, who shares that it was the favorite verse of Catherine, his deceased wife and the player character's mother. The Lone Wanderer is first introduced to the passage in the first tutorial quest and later in the game, after being reunited with their father, they learn that this passage was the inspiration for Project Purity. The code "216" is used to activate the water purifier.
