Mother of the Fog

Mother of the Fog (or Fog Mother, in-game name ghostly figure) is a Child of Atom who lives on the Island. She, thanks to her actions, became a mythical deity incorporated into the faith of the Children of Atom.

Background
A reclusive hermit, the Child of Atom who became known as the "Mother of the Fog" has been on the Island since at least before the Children of Atom were exiled from Far Harbor. She may have been one of the original Children to have set foot on the island or one who contributed to set up several shrines throughout the island. To travel about the Island undetected, she began to use Stealth Boys and was able to scavenge from across the Island. After she became a recluse, and long enough for most of the Children to no longer believe that she was a fellow child of Atom, she led the pilgrimage of exiles from Far Harbor to the Nucleus.

By this time, she became a mythical figure and incorporated into their faith as some sort of spirit, a creature of the wilds, a divine messenger and one of the holiest visions of the cult. She became described as a faceless figure, dressed in tatters and glowing, or rather, oozing fog. However, a few members still believe that she is just a hermit.Brian Richter: "Hmph. You're back. More than I expected. Did Atom reveal something to you?" The Sole Survivor: "I drank from the spring and a woman led me to this icon. Does this mean something?" Brian Richter: "A woman? Led you to that icon? What woman? What did you see?" The Sole Survivor: "Is there something special about this thing?" Brian Richter: "I think it may be a message from someone very important. So I need you tell me what you saw." The Sole Survivor: "It was... otherwordly. The woman, she was like a living shadow, cloaked in mist." Brian Richter: "Atom above. You really did see her. The Mother of the Fog. The Mother is a messenger from Atom. Acts as a guide to those important to His plans and the future of this family. She's the one who led the first of us to this place. And if she revealed herself to you... then I'd say the path He's lain for you is clear. If you are prepared to take the next step, then I believe there is a place for you among Atom's children." The Sole Survivor: "So what exactly happened to me at the spring?" Brian Richter: "Seems Atom granted you a vision. Only those deemed worthy of joining the Children have them... and live. But for some rare souls, he sends... more. A messenger. Or in your case, the Mother." The Sole Survivor: "So was the Mother real?" Brian Richter: "Most believe she's some sort of spirit, a creature of the wilds, though a few claim she's just an old hermit. Regardless, our family wouldn't be here without her. If she figured in your vision... well, there are few signs clearer you're meant to be one of us." (Richter's dialogue) She continues to watch over her fellow cultists from behind the veil of anonymity. She has observed High Confessor Martin come to question his purpose and leave the cult, the Sole Survivor or Kasumi Nakano arrive on the Island, and a group of Children being cornered in a ruin close to her camp at Haddock Cove.
