In the Palace of the Winding Path, on a desk next to a television, close to the north entrance.
One of the Palace knuckleheads turned on the Guided Meditation system this morning for shits and giggles.
And, due to that, we now know the sound of it drives those green mutant freaks nuts. They came from all over. Took us until after noon to fight them all off. Someone needs to tell Margie that we're glad to offer protection to the Palace in exchange for chems, but not if the dumb jerks are gonna invite the entire Wasteland to our doorstep.
