(Heh.)
Rob had never seen a Vault like that under the Cathedral. Vault 13 was well-worn, a place where generations had been born, had lived, had loved and had died. Vault 15 was rusty with neglect, open to the elements and wildlife of the wastes. The Vault under the Necropolis was industrial in nature. Debris was cleared and repairs were made, but people would never live in it if given the choice.
The Vault under the Cathedral was a madhouse.
Strange biomass covered machinery and floors, pulsing as if alive. Terrible experiments were performed by grinning madmen. Initiates to the Unity were chained up and brainwashed. Prisoners were kept in cells and given implants that would explode if they tried to escape.
"Nullified? Are they somehow restricting your physic powers through the devices you are wearing?"
"Yes... The walls are alive with those who have gone before."
"Others are in the wall?"
"Melding... No, meeting of the soul, to protect the Master of all."
"The Master? How do I get to him?"
"There is only peace and joining... the price... the pain... One must be blind... nulled."
"Nulled? So I need to wear one of those things?"
"Yes... I will anoint you... I will give what I must not."
"Hello Master. I'm Rob Snarker, and I'm-"
"Well, I'm didn't come here for a polite chat. I'm here to kill you.
"Fine. If you're going to attack me I might as well just give you a little present."
Rob pulled a bandoleer of grenades out of his pack as a group of supermutants rushed into the chamber.
"If you'll let me actually speak then you'll know that these are EMP grenades, the kind that scramble robots and machinery. The kind that you seem to be hooked up to."
Rob chucked the bandoleer at the Master, as each grenade went off in succession. The Master began to convulse and spasm as the power EMP waves coursed through his body. Eventually the Master slowly stopped twitching, its head and tentacles lying slack. Then slowly, as if in great pain, it raised its head to speak.
"Well, I was hoping that the EMP grenades would take care of you. No matter. I expect that hot plasma to the brain ought to be much more effective."
The supermutants watched in horror as the remains of the Master continued to flail about. One of them put his mini-gun up to his face and pulled the trigger. The rest fled. Smiling grimly, Rob reloaded his plasma rifle.
"Crap."
"Excuse me? Hello? Everyone just, yeah. You all seem like nice people. Well, better than the ones in the Cathedral at least. Long story short there is a nuclear bomb underneath the ground and it's going to explode in two and a half minutes. I'd start running."
