Fallout 4's Har Harbor DLC has plenty of content for players to absorb, including tensions between several key factions on the island. One of the central factions is the religious cult known as the Children of Atom, the arch-rivals of the residents of Far Harbor itself. Players can opt to join the Children of Atom, and will likely need admittance into their base, The Nucleus, in order to complete many of the main story missions in the Far Harbor DLC.
One of the first quests in the Children of Atom questline is "Visions In The Fog". Much like Fallout 3's "Walking With Spirits" quest in the Point Lookout DLC, this quest features a psychedelic sequence in which players will temporarily enter a hallucinatory state. One of the key challenges of the quest is locating the Shrine Password, which will be covered in depth below.
Fallout 4 Guide Hub: Weapons, Armor, Quest Walkthroughs, Tips, & More
Game ZXC's guide hub for Fallout 4 has tons of information to help players on their journey, including quest walkthroughs, weapon locations, etc.
Where To Find The Spring
Having arrived at The Nucleus, players will be halted by Grand Zealot Richter who tells the Sole Survivor that they must first complete an initiation ritual in order to be permitted access inside. Attempting to enter without having first completed this quest will be treated as trespassing and any Children of Atom guards will proceed to attack. Completing the ritual simply opens up the Children of Atom quests to the player, it is not a definitive choice in siding with this faction for Far Harbor's endgame.
The first objective of the ritual is to drink from a highly irradiated natural spring. Atom's Spring can be found slightly to the northwest of The Nucleus and is not a distant trip to make. Upon interacting with the spring, players will experience a hallucination in which a female figure known as The Mother of the Fog guides them to a crumbled building that serves as a shrine. The area is populated with plenty of feral ghouls, and a decent amount of radiation resistance will be required due to the thick, toxic fog.
Every Faction You Can Join in Fallout 4
While there are four major factions in Fallout 4, players can join several minor factions as well. Here's every faction that is joinable.
Where To Find The Shrine Password
Once the area is clear, players can head inside the building to find a locked room with a security terminal preventing access. Unlike ordinary terminals, this one cannot be hacked, and players must find the password as a clue in the surrounding environment. The password can be found on the side of the locker near the periodic table and reads: "MoThEr".
With the password examined and entered into the terminal, players will be free to proceed into the locked room and retrieve the Icon. The small wooden carving can then be taken back to the Children of Atom as proof of the task's completion.

Fallout 4 presents a richly lived-in world despite the desecration of nuclear war, but some of its most interesting scenes aren't in plain sight.
What To Do With The Icon
Now that the Sole Survivor is in possession of the Icon, they can return to The Nucleus and explain what happened to Grand Zealot Richter. After explaining the Mother of the Fog's appearance in the hallucination and agreeing to become a Child of Atom, players will be admitted into the submarine base.
Once inside, the Children of Atom questline will be opened, and players will be able to interact with several characters and vendors inside the base. The Icon can later be used in the quest "Reformation" where players can choose to replace the High Confessor Tektus with a synth as the leader of the Children of Atom.
