'What now?' Matt asked.
'Now?' Crowther grabbed Caitlin and made her stand in the focal point of the circle. 'You wait there,' he said to her, 'and do what I say the second I say it.' To Matt, he said, 'Meanwhile, we wait for the hallucinogen to take effect… and we hope.'
A sense of awe had descended on the entire stone circle, pregnant with possibility. No birds sang; the trees barely stirred in the breeze. The sun slipped to the horizon, bringing gold to the face of the stones, ploughing long shadows into the heart of the ring.
'A fairy circle,' Mahalia said in a whisper, the first stages of the trip evident in her voice.
'Exactly,' Crowther said. 'Metaphors and symbols, all hiding a deeper truth.' They listened to the silence for a few moments and then the professor added, 'We are Psychonauts, embarking on a journey beyond reality. Few have been this way before us.'
'Let's hope we come back,' Matt said.
'Look.' Caitlin/Amy pointed past the shimmering ethereal stones to a hazy area in the field beyond. Ghostly but unthreatening figures appeared and then faded, walking through their echo-lives oblivious to Crowther and the others.
'The dream zone,' Crowther said. 'Reality is thinning.'
Caitlin glimpsed people in ancient dress, images she distantly recalled from storybooks, some dressed in clothing styles she didn't recognise, others that looked barely human. And briefly she saw five people staring back at her — a man with dark hair, another whose torso was covered with tattoos, a thin Asian man, a woman with brown hair and another with dyed-blonde hair. They appeared to be trying to communicate with her, but they were gone before Caitlin appreciated their presence. Caitlin looked round; Mahalia had seen them too.
'Magic,' Matt said dreamily. 'Everywhere.'
'In the local stories, this place was supposed to be the favourite haunt of Oxfordshire fairies and Warwickshire witches,' Crowther said. 'The last Oxfordshire fairies were seen disappearing down a hole under these stones in the eighteenth century. It was reported, written down — an eyewitness account. Amazing.' The air had grown unseasonably warm, and a hazy, cosseting feeling enveloped them all; they felt at peace yet excited about what lay ahead. Distant music floated in and out of their hearing, merging with the sound of the wind.
But just as they began to enjoy the warm, joyful atmosphere, Carlton began to whimper. Caitlin didn't have to ask what was wrong: she could feel exactly what Carlton was sensing: a dull psychic warning of impending danger. If they hadn't been in that spot, tripping, they would never have perceived it, but now it was like an alarm bell tolling.
'What's going on?' Matt asked fearfully.
'Don't get worked up,' Crowther cautioned. 'The drug will magnify your emotions. You'll panic.'
'Don't get worked up?' Amy was gone, and now the neurotic, frightened presence of Briony dominated. 'You know what's coming.'
'What is it?' Matt said, urgently.
'Things have been tracking us,' Caitlin said. 'Tracking me. They won't give up.'
'Stay calm.' Crowther laid a heavy hand on Caitlin/ Briony's shoulder.
'What things?' Matt searched the area. The sun was now just a thin line of red at the horizon, and the shadows surged everywhere amongst the trees.
'The Whisperers.' Caitlin/Briony hugged her arms around herself.
'Can you feel that?' Matt stood up, ready to roam to the edge of the circle to search the growing dark until Crowther grabbed his jacket and pulled him back down.
And then they all could feel it: a wave of black despair washing across the land, rising inexorably up to the higher ground where the stones looked out. The Whisperers were coming.
'What are they?' Caitlin/Briony asked desperately. 'How can they make us feel this way?'
Mahalia grabbed Crowther's arm and said ferociously, 'How much longer before this thing works?'
'I don't know. I don't know if it will work.'
Mahalia whirled around. 'We're too exposed here. We need to find shelter… somewhere we can defend.'
'They shouldn't be able to step into the circle,' Crowther said. 'The Blue Fire will keep them out.'
'But if we don't cross over, they can just wait outside the stones until we starve,' Mahalia said.
A thin purple light was visible far away down the valley, but drawing quickly closer.
'Come on!' Caitlin screamed. It felt as if all her occupants were struggling to gain control.
The remaining sun was just the slightest sliver, as if the sky was cut and bleeding. Yet oddly the blue glow edging the stones was growing brighter, running in veins and capillaries down the very rock as if infusing them with life. The air became charged with magic.
A ragged breathing rose above the stillness. Mahalia drew one of the knives from her harness and turned in the direction of the sound. Purple mist drifted languorously through the trees and soon after a figure came stumbling through it. But this was not one of the Whisperers. It had the shape of a man, though the purple light was leaking out of him as if he were a fractured steam pipe.
Carlton whimpered; Mahalia crouched low to the ground, ready to fend off any attack.
The figure reached the edge of the stones and they recognised him as the hermit who had tried to drive them away from the Motor Museum. But he was no longer as he had been.
'My God! What have they done to him?' Crowther breathed, transfixed.
The man could barely be called that any more. Bones protruded through his skin as if it had been broken and the frame had torn through, but without blood; instead there was that purple light. His skull shimmered in a spot where there should have been hair and scalp; an eye stared out of a harsh orbit. He somehow managed to lurch forwards even though a thigh bone was cracked and exposed. The numerous ridges and furrows of exposed bone made him resemble some kind of walking dinosaur.
And as he moved, he moaned, a thin whine of pain and despair that provided a backdrop to words that could not have been his. 'There is no hope,' he said with an unsettling, otherworldly sibilance. 'It ends here. You end here.' Rusted sword-blades emerged from both of his hands where they had been embedded in the bone.
Behind him came the dark, lumbering shapes of the Whisperers on their mounts, black against the shadows but their eyes lit with purple. The colour itself had begun to make Caitlin feel queasy. They were approaching the circle on every side, drawing in their ring of terror.
And if they couldn't enter the circle, their herald had no such qualms. He crashed across the barrier, swinging those sword-blades wildly. Mahalia ducked at the last moment, narrowly escaping the loss of her head. Carlton scampered on all fours to the other side of the circle where he was feverishly aware of the Whisperers just a stone's throw away.
The man turned on Crowther, his crazed attacks unpredictable.
'LET ME OUT!' The terrible voice roared at the back of Caitlin's head: the Fifth, the one the others all feared. 'LET ME OUT! LET ME BRING MY FURY TO BEAR!'
'No!' Caitlin told herself. 'Never, never, never.'
Matt threw himself forwards, knocking Crowther out of the path of the killing blow. The sword drove into the soft earth.
'Life winds down to decay, then death,' the herald continued. 'All things are ending, always.'
The drug was slowly working its magic in all of them, spinning up the spiral dance of the trip. The visual hallucinations were taking over from the auditory and emotional twists. The world within the circle was like a dream of bursting flowers and life, while the darkness howled at the stones from without.
'Now!' Crowther yelled at Caitlin. 'Slam your hand on the ground! There! There!' Frantically he pointed to a spot near her feet.
Caitlin did as she was told and instantly lines of Blue Fire ran from each stone towards a focal point in the centre of the ring. The coruscating energy crackled, rising up like liquid, then forming odd geometric shapes. A massive structure of shimmering sapphire was forming over them.
