“When the Dark comes rising, six shall turn it back,
Three from the circle, three from the track;
Wood, bronze, iron; water, fire, stone;
Five will return, and one go alone.
Iron for the birthday, bronze carried long;
Wood from the burning, stone out of song;
Fire in the candle-ring, water from the thaw;
Six Signs the circle, and the grail gone before.”
The Signs which Will hunts down in the book take the form of quartered circles, one each made of wood, bronze, iron, water (an opalescent stone), fire (gold), and plain stone. Craft something inspired by one of the Six Great Signs of the Light. A literal interpretation (a quartered circle), something decorated with that motif, spun fiber inspired by the materials used to make one of the signs, or whatever else your imagination may present.
