Walking with Spirits

 is a Fallout 3 quest and achievement that is added to the game with the Point Lookout add-on.

Finding the Tribals
You receive this quest from Desmond after defending Calvert Mansion from Tribals, Desmond asks you to infiltrate the Tribals to find out why the Tribals are attacking Calvert Mansion. You are directed to the Ark & Dove Cathedral and talk over the intercom with one of the Tribals. After accepting his mission, he will send you on a test. He tells you to go to the Sacred Bog Entrance and once inside, search for the mother Punga plant and take her giant seeds.

Seeds of Vision
Once inside the bog, you will fight through several mirelurks. Upon making it to the final grove, the Mother Punga, and its purple seeds, will be ready for the taking. However, it is recommended, if so inclined, that you take the Punga Fruit before activating the Mother Punga. Once activated, nothing will be able to be picked up until the Punga effects wear off. When you take the seeds of the plant a gas sprays out from the fruit and your character falls over.

When you awake, you experience a psychedelic hallucination. You will find giant bobbleheads, called Schmault-Tec Bubbleheads, with cryptic messages written on them, ranging from expressing the PC's inner doubts and fears, to making fun of his/her misfortunes. It is also possible to see a large red translucent saw which is randomly sawing the ground, or even exploding Nuka Cola Quantums that make baby sounds when they explode. You can also see silver needles sewing or putting stitches in the ground, as if you were getting stitches. You can also hear a violin playing, the apparent result of several nearby trees shaping into the instrument. You will be attacked by ghost Ghouls (that won't hurt you), journey through an upside-down swamp, and even find the skeleton of your dead mother (with a nearby bobblehead explaining that it would have abandoned you too). You will find several dead bodies of people from the Capital Wasteland that disinegrate when searched, including Moira Brown, Amata, Elder Lyons, and an unnamed Settler, possibly the Megaton Settler who gives you items for having good karma. Finally you find the Megaton bomb with a character similar to Mister Burke named Mister Break standing in front of it. In the background behind the bomb, the Washington monument can be seen. The Mister Break character is actually the person who "frees your mind" but is seen as Burke. He warns you to take it easy before the bomb explodes and you awaken in front of the Sacred Bog.

Return to the Tribals
When you return to the Ark & Dove Cathedral, you are permitted entry. If you enter third-person, you will notice that any headwear you had equipped is presently gone, and you have a large scar on your forehead. You will be unable to equip the headwear you were wearing until you have the scar removed by Nadine. Apparently, she has joined the Tribals to procure their Punga, in failing to achieve her original goal of discovering treasure in Point Lookout.

Understanding the Visions
It is later revealed that Tobar follows the Lone Wanderer into the Sacred Bog. He then takes the PC while unconscious and removes a piece of brain. After undergoing the procedure administered by Tobar, the Point Lookout Tribe accepts you as one of them. Before awakening at the Sacred Bog Entrance, you will experience a hallucination, which can be interpreted as follows:


 * The saw cutting could be the moment when Tobar is opening your head/skull.
 * ALL of the weird things may be when he is removing the brain tissue.
 * The needle that "sews" it's way along the side of the path in front of you is when Tobar is sewing the wound shut.
 * The part where Mr. Break talks to you, it is actually Tobar talking to you when you're unconscious.
 * The bobbleheads explain all of the lone wanderer's self doubt and confusion. For example the Intelligence bobblehead comments on how he/she fell into another trap, while the Charisma bobblehead explains that if the Wanderer's mom had survived, she wouldn't have wanted him/her.
 * Mr. Break cannot be killed instead he will just go unconscious!
 * Just before the end of the hallucination, the PC runs into the floating dead bodies of a Wasteland settler, Amata, Elder Lyons and Moira Brown. If you interact with the bodies, they disappear in the incinerating fashion like in Operation Anchorage.

Reward
Access into the Tribal's headquarters.

Trivia

 * Mr. Break has an Irish accent that is very similar to Colin Moriarty.
 * Sometimes, if you closely examine the corpses of the settler, Amata, etc., you will notice that they still blink...
