Object 621
The Holder of Cataclysm
Go to the house of your closest friend. Make sure he/she has at least one sibling, either there in the home or somewhere in existence. Go to their restroom, place your hand on the mirror or, if they haven't one, the wall opposite the toilet. Ask it to see "The Holder of Cataclysm", or to take you to the shadows.
Either way, you will be pulled to an alternate realm, where it is dark, but you are able to see perfectly. Everything is in reverse and, where your shadow was, a full-color version of you is. You are now your shadow. Step out of the room.
You should be in the same house, with everything in a similar fashion as to how it was in the restroom. Your friend's shadow or, rather, the Holder of Cataclysm, will be there. He/she will hand you a rock, which, over a course of 4 days, you must break open. If you fail to do so, you will be stuck in the Shadows forever, where everything in your life will be perfect, this being your torture.
In the Shadows, everything is reversed. All Pleasure will be felt as pain, happiness as sadness, and so on. The Shadows will continue to attack you with happiness for one month; when you will be brought back to the house to open the rock in 3 days. If you are unable to, the cycle will repeat, only you will have a 2-month wait and 2 days to open it, and the cycle repeats until you are stuck in the Shadows for eternity, or you escape.
The usual reason souls are bound to the shadows is that they assume that they must open the rock with their hands. This, however, is not true. While any item in the Shadows passes through your hands, you may bring Objects into the Shadows. Any contact between the rock and an Object will destroy the rock, and, thus, you'll receive the key inside.
It is at this point, whether you opened it with your hands or with an Object, that you hold the key in front of the Holder and ask it, "Is the Gathering natural?" The origin of the Objects will be told (or repeated if you've already heard it, but with the answer to the question inside). He/she will then hand you the same rock you'd just split open, but with a keyhole in it. If you stick the key in now, you will be sucked into a hole, and taken back to the real world. If this happens, you will not leave with the object, and may never come back.
Before leaving, touch your hand to your friend's shadow. If (one of) their sibling(s) comes through the door at that moment, he/she will approach you with the object, a necklace with an eye charm on it. If he/she does not, you may leave freely, but without the object. If you should be confronted with an image of a dead sibling, then close your eyes and prepare for the coming finality.
The necklace has the power to - 40 days and 40 nights after every use - cause cataclysmic events; i.e., a tsunami, hurricane, volcano eruption, earthquake, tornado, etc. The necklace also sends out a radio transmission on every station (as a loud, blank beep) everywhere in the world when used, which can be traced to you.
The necklace is Object 621 out of 2538. He will know when It shows.
