The young man cackled, if a young man can cackle, when she showed him the medallion and asked her question, "No, no, nothing. Nothing is wrong with it, nothing at all." He spoke slowly, tracing each syllable with his tongue.
Sandra persisted, "It's the symbol for infinity, but it's sideways. See, the loops are supposed to be on the sides, not top and bottom."
The young man's smile grew wider. "No, it's not Infinity, definitely not Infinity. It is easy to mistake a Year-Glass." He stretched the word, Glass, into a soft hiss.
Sandra looked again at the medallion. An inch tall, it certainly looked like a lemniscate - the symbol mathematicians have used for unimaginably large numbers, a figure eight stretched and turned on its side. This medallion, "A Year-Glass," Sandra breathed, appeared to be turned on its side again - apparently only a stretched figure eight, with a tiny loop at the top. A simple white string made the medallion into a necklace. Heavy for its size, it rested comfortably in her hand. She traced the delicate curves with a long finger tail, shivering at the rough scales etches painstakingly into the metal. Bluish glass filled the two loops, bulbing slightly to either side. She pointed to two small slits, one on each loop, on the sides of the Year-Glass. "What are these?"
The young man's smile, already splitting his face, grew again. Somehow that smile became grotesque, but Sandra was not looking at him. "That, my dear, is how the Year-Glass works. You put something of yours in the bottom - a hair, a tear, a dream. You put something from someone else in the top. The Glass steals from the top, and gives to the bottom, you see."
"Steals?" Sandra glanced up, but only briefly.
"Steals, takes, retrieves, gives, yes, yes. All those things; a Year-Glass has much magic."
"Steals what?"
"Life, mostly, but it can steal other things, too. It depends, I can't really say on what."
Now Sandra laughed. "Right, okay. Steals life." She shook her head, then held it up to the light. "It is pretty though." She weighed it another moment in her hand, in her mind. "How much?"
