Linda, the acting head of the ASMC this year, stood in the vestibule of this year's Macabre Magic event. It was a simple shack, but everyone knew that wasn't the end of it. "Good evening," she said to her willingly captive audience. "As is tradition, I am required to explain and demonstrate the rules of this event. First," she raised one finger, "We are all here of our free will. There is no coercion, no threats or any other way to force you to enter. If you don't want to, you can leave and no one will stop you. By the same token, once you enter, you stay until you leave, and then you cannot re-enter."

She waited, and no one left. "Thank you again," she announced. "Now, some quick information for everyone. I see some of you have come prepared with your costumes, while some are waiting to enter to put them on. When you enter this," she indicated the shack behind her, "there will be changing rooms on the right and the left. These are also the points that you will return to when and if you choose. If you happen to do both at the same time, well," she shrugged, "I won't mind at all. Bathrooms and washrooms are also in the main hall, and they are fun-free zones. Just business. Entryway to the event proper will be down the stairs. For this year's theme is Dungeon, and that means exactly what you think it means." She smiled as the crowd seemed pleased by this.

"Now, do remember that by entering you are giving consent to anyone to do anything they like to or with you. But this does not mean that you have to be rude about it. Sometimes, people need a breather, or they are planning ahead for something else. Respect your fellow event-goers," she warned them all sternly, "or I will eject you."

The threat was absolute.

"Be that as it may, the active members of the Club, including myself, will be out and about, enjoying ourselves, and we will gladly help you out in any manner you choose, from questions to suggestions to whatever you fancy. We are here for your entertainment. Other than that, you will find a great variety of tools and toys to have fun with this evening, and given that we have been taking suggestions since last year, I'm sure you'll all find something to your tastes."

"And so, with the obligatory warnings out of the way, remember that at this shindig, violence and pleasure are the same thing," Linda said. "And as per tradition, I am to begin the festivities with a visceral reminder of what is to come." With that, Linda backed up to the door to the shack and reached out to the sides with her hands to grab a pair of handles that seemed to emerge from the woodwork.

A roaring chainsaw burst from between her breasts, the metal's scream as high pitched as her own as the saw was roughly pulled down, splitting and spilling as it ground down her ribs, her stomach and out her sex. Those closer could see the sawblade was between the two-sided door, but everyone could see the saw rise again, catching and splattering viscera all over as it rose up into the cut it had already made and then higher into her collar, then ripping her head apart.

The sawblade was withdrawn as the two halves of Linda slumped, the insides quickly becoming the outsides. The door was then pulled open, the corpse still holding onto the handles with the stiffness of death. Inside was Lindsey, dressed in nothing, but still holding the chainsaw in her hands as it idled. "Welcome inside everyone," she said. "To enter, pass through her body." She shouldered the chainsaw. "I will see you inside, and if you're lucky, this too," she patted the murder weapon with one hand, turned and walked into the darkness.

Everyone followed.
