“It’s like invisibility,” I said to myself cheerfully. A ring of invisibility will always work, even though invisibility is one of the harder spells. For some reason, even though it is straightforward to make the empty air take on solidity in illusions, it is very hard to make solidity look empty. There is probably a good theoretical explanation, but I have never paid much attention to theory, preferring the practical.

I paused to see how well I could make myself invisible. I had been working on the spells intermittently for almost a year now. Concentrating hard, breaking off pieces of the flow of magic and controlling them with the Hidden Language, I watched my feet disappear, first the left one, then the right one. At this point, however, things stopped. My knees remained obstinately visible. I snapped my fingers in disgust and my feet came back. Just last week I had made it almost all the way up my thighs.

“But I’m not trying to make a ring of invisibility anyway,” I told myself firmly. “I’m making a communications string.” I put both hands on the string and concentrated on it, thinking of how one reaches out, slides just the corner of one’s mind into the stream of magic while leaving most of it firmly anchored to one’s body (one of the most dangerous moments for young wizards is discovering how to slip one’s mind out without losing oneself forever). I alternated the spells that seek another mind with attachment spells, and suddenly the string stiffened and glowed pink.

I rushed out into the courtyard. Since it was Sunday, the servants were only doing necessary chores, and a number of them were now playing volleyball while the others watched and cheered. I found my own saucy servant girl, flushed and laughing after having just been replaced at the net.

“Come on,” I said, “I need your help with a magic spell.”
