The Holder of Armageddon

In any city, in any country, go to a mental institution farther away from your last encounters. When you meet a security guard, you must say you seek for the one who calls himself "The Holder of Armageddon". If the security guard pulls out a taser, run and don't look back, and don't go back to the mental institution, you've failed.

But if the security guard had a worried sigh and leads you to a dark room, just move straight. If you even slightly touch the walls, you will awaken "the living wall" and you will be crushed to death. If you pass this, you will see 666 doors, odd as it may seem. Take the 666th door. If you would've taken the others, you would've been plunged into a pit of suffering and damnation. You will then see a black-haired man. The only question he will answer is: "Why does evil and destruction exist?" He will then appear behind you. Stare into his eyes. You will see visions of the devil and his minions. You will then wake up next to a scythe.

This scythe is Object 666 of 2538. The end is nigh and you will be the first to go.
