Holder of nothing

In any city, in any country, go to any mental institution you can get yourself to. When you reach the front desk, ask to visit someone who calls himself “The Holder of Nothing”. Should a look of sheer, primal disgust mar the workers expression, you will then be taken to a separate building, which appears to be an old, wooden outhouse. Inside will be a seemingly endless corridor far, far longer than the length of the outhouse.
There will be no sound in the corridor. Attempting to make any at the wrong time is a grievous, grievous mistake. You will notice the lights in the corridor get brighter and brighter as you make your way down towards the end, becoming nearly blinding. If at any point the lights go out, QUICKLY shout out “No! Stop! What you are doing is wrong!” while backing away. If the lights do not come back on, bolt for the door you came in through. It should still be open and hopefully you aren’t far enough down the hallway for them to close it on you. If they manage to close it, hell itself would be preferable to what you will suffer.
If the lights come back on, return to walking forward down the corridor. Upon reaching the cell, the worker will open the door for you while glaring at you in disgust. Inside the cell will be a mad pastiche of colors, arranged in several harlequin-like formations. You must not be distracted by them; for at the center of a room is a naked young woman, slathered in blood and bound by strips of human sinew. If you take your eyes off her even for a moment, she will destroy you utterly. She will only respond to one question. “What were they when they were one?”
She will then stare into your eyes, and speak the answer in incredible detail. It will be unlike anything you have ever heard and you will be on the verge of both ecstasy and agony at her mere words. It is not uncommon for most to lose themselves in the euphoria. The worst thing you can do, however, is look upon the tattoo on her chest. It will pull at your mind to gaze upon it, but you mustn’t. If you do, you will be hers.
She will flay you alive and add your mutilated flesh to her bindings, and you will remain trapped with her, fully conscious, for the rest of time.
That tattoo is object 4 of 538. They desire to be one again. But they mustn’t.
