"I thought you were supposed to have killed Morgan La Fae?" I said, hoping to change the subject.

"I did my best," Merlin said dryly. "But I was never sure ... She always said she'd be back. Mind you, Arthur said the same thing, and I'm still waiting."

"So you're not just hanging around here for the return of your heart," I said.

Merlin nodded slowly, acknowledging the point. "Arthur ... was special. I made him possible, plotting with Uther Pendragon, back when I was still playing Kingmaker. But Arthur turned out to be so much more than anyone ever thought or intended him to be. He made himself special. He was the best of us all. The only man I ever followed. I dreamed a great dream for him, and he made it come true. A single great land, founded on Reason and Compassion, sweeping aside all the old madnesses. The holy Realm of Logres, burning so very brightly in a Dark Age."

He paused, his chin resting on one hand, remembering. "I could have been much more than I was. I was supposed to be the Antichrist, the Devil's only son born of mortal woman; but I declined the honour. I was wise, even as a child, and I determined that I would follow my own path and no other's. I killed all the members of the coven that conspired to bring me into being, and all those who came afterwards, to ensure my freedom. My mother was already dead-some nameless witch who did not survive my birthing. Apparently I tore her apart, clawing my way out of her, impatient to be born."

"What about your... father?" I said.

"We don't talk. I kept myself busy for years, amusing myself with building up Kings and countries, and then destroying them. And then I met Arthur, and that changed everything. He shamed me, for the shallowness of my vision. I loved him. He was my father, my son, my light in the endless dark. I knew that Hell was real, but he made me believe that Heaven was, too. I gave him my life. I would have died for him, but... I always knew I couldn't save him without making him over into something he would have abhorred. He proved his dream worthy by dying in defence of it. He and Mordred met on the battlefield and died in each other's arms, neither ever really understanding what had brought them to that bloody place. I was elsewhere, killing Morgan La Fae. Afterwards, with Arthur and Camelot gone, I didn't much care about anything any more. It was almost a relief when dear, treacherous Nimue came along and found me. She really was magnificent, boy."

I decided it was time to change the subject again. There's nothing worse than a centuries-old corpse getting maudlin. "What do you know about the Nightside's beginnings?"

Merlin stirred on his iron throne, his face cold and considering once again. "When I was young, I learned from the Powers that came before me. They taught me that the Nightside was originally created, by forces unknown, to be the one place on earth free from the control of Heaven or Hell. The only truly free place. That's why I've been able to remain here so long, despite my... diabolical beginnings. But that's really all I know for sure. You need to speak to Powers older than I. One of my old teachers is still to be found here in the Nightside, though I understand he is no longer what he once was. Herne the Hunter, the free spirit of the wild places, leader of the Wild Hunt. The untamed savage. The force that drove the great green dream of Old England, when the forests were still huge, dark and primal places."
