Walking with Spirits

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

Ark & Dove cathedral
After the Lone Wanderer assists Desmond in defending the Calvert Mansion from tribals, Mr. Lockheart's next request is to infiltrate the Ark & Dove cathedral to the north, which serves as the tribals' base of operations. He requests assistance in discovering the reasoning behind their attacks. Although the cathedral gates are locked, a guard sees the Lone Wanderer from a distance and speaks to them via an intercom. He sends the Lone Wanderer to the rite of initiation, out west into the sacred bog entrance to take part in the Ritual of the Mother Seed.

Sacred Bog hallucinations
Inside the bog, many mirelurks or possibly swamplurks appear, depending on the player character's level. At the final grove, purple seeds can be harvested from the Mother Punga plant. Once the Mother Punga is activated, it will no longer be possible to pick anything up until the punga effects wear off. Taking the seeds of the plant causes the Lone Wanderer to become incapacitated by way of a gas or vapor it emits.

The Lone Wanderer then experiences a series of hallucinations as they progress away from the Mother Punga plant. They will first experience a vision of a large red translucent bonesaw that is sawing into the ground. Next, Nuka-Cola Quantums explode as one approaches, and the sound of babies can be heard. The Lone Wanderer will then witness dolls on poles, gesticulating with their arms. Next to this vision, needles sew stitches in the ground.

The Lone Wanderer then experiences a vision of several trees that have grown into the shape of violins, and the instrument can be heard playing nearby. Ghost ghouls will attack next, but will cause no damage. Journeying through an upside-down swamp section leads to a skeleton labeled "Mom" on an operating table, surrounded by party balloons. Further on, there are several dead bodies of various people from the Capital Wasteland that disintegrate when searched, including Moira Brown, Elder Lyons and Lucas Simms floating by the rocks to the left of Amata and an unnamed settler.

The last vision the Lone Wanderer experiences is a large version of the Megaton bomb with a character that looks like Mister Burke standing in front of it, named "Mister Break." In the background behind the bomb, the Washington Monument can be seen. The vision of Mister Break speaks to the Lone Wanderer in Tobar's voice. He says, "Congratulations, my boy/my dear, you are going to pull through and everything will be right as rain." When spoken to, he will say, "No, no. Don't try to get up yet. You'll only hurt yourself." The bomb then "explodes," shaking the screen but does not deal any damage. The Lone Wanderer then finds themselves at the front of the sacred bog entrance, no longer hallucinating. At this point, it will be possible to enter the Ark & Dove cathedral, ending the quest.

Schmault-Tec bubblehead
Immediately after leaving the Mother Punga area, the Lone Wanderer will see the first of seven giant bobbleheads labeled "Schmault-Tec bubbleheads." It is possible to read messages written on them, but they cannot be added to the player character's inventory nor do they add any benefit. Messages are listed below in the order they are encountered.

Reward
Access to the tribals' headquarters, 300 XP, and the Punga Power! perk.
