And that was when I noticed something ... odd. Despite all the tension and chaos, and the threat of imminent violence on all sides, I was humming the tune of an old song from the seventies. It was "Bridget the Midget the Queen of the Blues"; one of those comedy novelty singles by Ray Stevens. Hadn't thought of it in years. Even stranger, most of the people nearest me were humming the same tune. Some had even broken off bidding to sing along, though their expressions suggested they didn't know why. I got chills up my back, as I realised the song was spreading through the crowd. In the Nightside, coincidence and compulsion often meant something. And what it usually indicated was interference from Outside.

And then even Grave stopped taking bids and rubbed hard at her forehead, as though bothered by some intrusive thought. Sandra Chance and the Painted Ghoul were both on their feet, looking confusedly about them. A growing murmur of unease ran through the crowd. The song's moment had passed, but we could all feel something—a growing sense of pressure from a direction none of us could name. More people rose to their feet, looking round wildly. No-one new had come into the Hall, but we all knew we weren't alone any more.

"Something's coming," said Sandra Chance. "Something bad."

A few people protested at the interruption of the bidding, but were quickly shouted down. Pretty much everyone was on their feet now, looking around for threats but seeing nothing. Various weapons appeared in nervous hands. The teddy bears huddled together, hints of claws appearing on their padded paws. The Hall grew silent and tense. There was a growing pressure on the air, like a gathering storm, like the moment before lightning strikes. And suddenly, all around the Great Auction Hall, wards and protections that had stood for centuries broke and blew apart in coruscations of vivid energies, shattered by a growing presence they were never meant to contain or keep out—a living presence, vast and inhuman, seeping into our reality like poison into a clear spring.

I knew what it was, what it had to be. I recognised the signs. A psychenaut; a traveller from some higher or lower dimension. An intruder that could not be stopped or turned aside because it was either too real or not real enough to be affected by human powers. I'd had some experience with psychenauts, back when I apprenticed with old Carnacki, the Ghost Finder. It didn't seem fair that I should have to face something so awful twice in one lifetime. I would have run, but I knew I'd never make it.

The crowd was already beginning to panic when the first protrusions from a lower dimension began to manifest. Unfocussed energies sleeted through the Hall, sparking black rainbows and shimmering auras around people who weren't actually there, before sinking into physical objects and lending them a horrible animation. Ugly, distorted faces formed themselves out of the materials of the walls, floor, and ceiling. Thick lips curled back to reveal jagged teeth, while dark eyes rolled grinding in their sockets, and abhuman voices shuddered through our heads, saying We are coming, we are coming. The wooden fingertips of a huge hand thrust slowly up from among the rows of seats, and the crowd scattered, shrieking and screaming, and shouting Words of Power that had no influence on what was forcing its way into our world from the underpinnings of reality.

The cheap wooden seats suddenly exploded into lashing wooden tentacles, springing out to wrap themselves around the fleeing crowd, holding them tightly. More screams rose as arms and legs broke under the inhuman pressure of the wooden bonds. Great faces in the floor drank up the spilled blood, making noises thick with meaning that predated language. The walls were swelling in and out, as though in rhythm to some great thing breathing, and the whole Hall shook, the floor rising and falling like a ship at sea.

Poltergeist activity stormed all around us. Events were happening so fast now no-one could react quick enough to keep up with them. Any object left unsecured flew violently back and forth, or spontaneously combusted. Clothes grew too large, or ripped and tore as they shrank. Fires burned unsupported on the air, and beads of sweat rolled sluggishly up the walls. There were hails of stones and rains of fish, and people spoke in unknown tongues.

I fought my way through the chaos to grab hold of Lu-cretia Grave, who was on her knees and clinging numbly to her rocking podium. I hauled her back onto her feet, and she clung to me like a child. I had hoped she'd have some emergency backup magics she could call on, but it didn't look like it. The teddy bears were staggering back and forth among the panicking crowd, trying to help, but there was little they could do except try and shield people with their padded bodies.

A genius loci invaded the Hall, overpowering and supplanting the old Barn's actual ambience, and, immediately, powerful emotions stormed our minds, slapping aside our defences with contemptuous ease. People began laughing, crying, and howling with an hysteria that shook them the way a dog shakes a rat. I was laughing so hard I hurt, but I couldn't stop. And then the horrors swept through us all, the same basic fears; of the dark, of falling, of people not being who we thought they were. People struck out at each other because they had to strike out at something. Men and women fell down and did not rise again, forced into cata-tonia by terrors and emotions they couldn't face. There was a new genius loci in residence, and the Great Auction Hall had become an alien, unbearable place. A few people staggered towards the exits, only to find that the doors had disappeared. There was no way out any more.

Jackie Schadenfreud had swollen up like a blowfish, blowing off all the silver buttons on his Nazi greatcoat. He giggled painfully, soaking up the emotions around him, force-fed on feelings beyond his appetite or capacity. Thick bloody tears ran down his pink cheeks as his eyes bulged in their sockets. His dog had already torn its own guts out. The Painted Ghoul ran up a swelling wall, scuttling like an oversized insect, trying to get away from emotions he usually inflicted only on others. Sweat was making his makeup run, and he wasn't smiling any more.

Sandra Chance's magics were mostly useless, being concerned primarily with the dead, not elementals, but she was still fighting back. She stood proudly in a shimmering circle of protection, magnificently angry, forcing back the psychenaut intrusions by sheer force of will. She had an aboriginal pointing bone, and in whichever direction she trained it the animating forces were thrust out of the material world. But only for a while. They always came back.

The Lord of the Dance and the Dancing Queen, united again by the threat of a common enemy, beat out powerful harmonies on the heaving floor with their dancing feet. They danced their fury and their outrage out into the world, forcing back the invading presences. Their feet slammed down, hammering out marvellous rhythms, their every movement wonderfully graceful, their bodies radiating defiant humanity in the face of the inhuman. They had always danced their best when they danced together.

Deliverance Wilde stood inside a faerie ring, protected by her compact with the Unseeli Court, but helpless to do anything. She wrung her hands together, looking piteously about her.

And I stood alone, only marginally affected by the horrors around me, and reluctantly decided I'd have to do something.

I don't like actually having to do things. I like to keep what I can and can't do a mystery; it helps build my reputation. You can do more with a bad reputation than you can with any magic. Usually. But while the Psychenauts were holding back from me for the moment, perhaps confused by my nature, there was no guaranteeing how long that would last. I knew what the problem was, and I thought I knew how to solve it, so once again it was up to me to haul everyone back from the gates of Hell. If I was wrong, the odds were I was going to die, in any number of really unpleasant ways; but I was used to that.
