The One

 is a undetonated bomb found slightly north-north west of the Devil's Throat. It only appears if the player has chosen the Wild Wasteland trait.

Layout
You get 1-3 rads when next to the bomb. There are 2-4 super mutant masters in a camp near it. There are also several glowing ones or super mutant masters roaming around the area.

Notable loot
The player can salvage components (150 energy cells, 50 microfusion cells and 2 sensor modules) from The One with a science skill of 61.

Bugs

 * While the check will say 60, the player will not be able to "disarm" the bomb unless 61 or more.
 * the campfire makes the noise of some kind of pump or machine similar to that in the securitron vault
