Aeld sat down in the snow and gestured at me, and I did the same, far more awkwardly as my leg pained me.
“As you know, our world abounds with spirits,” he began, laying his staff across his lap and speaking in a lecturing tone. “Most of these are simple land spirits, barely aware and easily controlled with a circle and a basic ritual. Commanding these is a simple matter; they accede readily to the will of any menskallin, and they present little danger even to an untrained spirit.
“However,” he continued, “an undvarn is a different matter. Each is possessed by a close spirit, usually a Hunt Spirit or Death Spirit, and these are both aware and intelligent. They resist being controlled or commanded and will try to escape a circle placed around them. Attacking their mortal shell doesn’t weaken them as it would a beast spirit, and had you killed the undvarn, you would have simply freed the spirit to find another vessel to occupy. To truly defeat one, you must bind that spirit, and to do that, you must first subjugate it through spiritual combat.”
He pulled out what looked like a copper knife from his waistband, and I tensed slightly, but he simply took it and lightly stabbed the underside of his forearm before sliding it back into his belt. He squeezed a couple drops into the snow between us, and with See Magic active, I saw them glowing dully in the darkness. He touched his arm, and the bleeding stopped, then he gestured toward me.
“Place your wounded arm on top of my blood,” he instructed.
“Why?” I asked warily. I really didn’t want his blood in my cut; that seemed really unhygienic, for one, and I had a feeling it could be a bad idea in a magical sense, for another. Magic still radiated from his blood; it was faint, but it was there.
“To initiate a spiritual contest, you must first link to the one you would battle. A melding of blood is the easiest way to do this.”
“Wait, you want me to fight you?” That startled me a bit, but he chuckled in reply.
“The rashi may talk about careful instruction, but I’ve found that the best way to learn is by doing. I can show you in an instant what would take days to explain, and I promise that you won’t be hurt by the experience.”
“Could he hurt me through his blood like that, Sara?” I asked silently.
“Yes, John,” she replied gravely. “In many worlds, blood is a conduit for magic. If you have someone’s blood, you can bypass a lot of their defenses, and the same applies if their blood is touching you.” She paused. “However, I think you’re right that if Aeld wanted to hurt you with magic, he would just do it. Your Resist Magic ability would help, but it’s not meant to be a primary defense. Until you learn more about this world’s magic, you don’t have any defenses to speak of, not really.”
“Sad but true,” I sighed. Hesitantly, I reached out and touched my arm to the spots of blood cooling in the snow. Instantly, I felt myself rising once again as the world lit up in the same hazy, silver glow I’d seen before. This time, though, with See Magic active, it looked very different. Bands of energy stretched all around me, some as this as threads and others at thick as bridge cables. The shapeless blobs I’d seen before now burned with power; the ones floating in the sky looked wan and feeble, but the shape wrapped around the mountain blazed like a sun. Fortunately, something shaded me from that radiance; when I looked around, a bubble of translucent energy surrounded me, rising from Aeld’s circle and wrapping about me like a shield—or a prison, I suppose.
“I think you could get out of it if you wanted, John. Aeld didn’t put all that much energy into it, I don’t think. It feels more like a precaution than an actual defense.” Sara’s voice still echoed in my mind, and I felt a wave of relief at the sound. I’d been half afraid that whatever was happening might leave me cut off from her, but obviously, that wasn’t the case.
I spun at the sound that echoed in me, not really heard so much as felt in my depths. A humanoid shape stood before me, larger than me and swirling with multiple colors. Dusky orange stained its light gray body, streaked with milky white. Blue-white seeped from its core, and light purple bands rippled along its surface, shifting and moving constantly. It took me a second to realize that I was looking at Aeld, and when I did, I glanced downward to see our bodies seated below us, still and silent and strangely empty-looking.
I tried to ask him what would happen if something took my body, but no sound came from my mouth no matter how I struggled to speak. Aeld must have sensed my attempts, though, as his voice sounded in my mind once again.
