He looked down at his thin arms, wet with cold fogdew, and raged at his weakness, for he knew his strength. There was power in him, if he knew how to use it, and he sought among all the spells he knew for some device that might give him and his companions an advantage, or at least a chance. But need alone is not enough to set power free: there must be knowledge.

The fog was thinning now under the heat of the sun that shone bare above on the peak – in a bright sky. As the mists moved and parted in great drifts and smoky wisps, the villagers saw a band of warriors coming up the mountain. They were armored with bronze helmets and greaves and breastplates of heavy leather and shields of wood and bronze, and armed with swords and the long Kargish lance. Winding up along the steep bank of the Ar they came in a plumed, clanking, straggling line, near enough already that their white faces could be seen, and the words of their jargon heard as they shouted to one another. In this band of the invading horde there were about a hundred men, which is not many; but in the village were only eighteen men and boys.

Now need called knowledge out: Duny, seeing the fog blow and thin across the path before the Kargs, saw a spell that might avail him. An old weatherworker of the Vale, seeking to win the boy as prentice, had taught him several charms. One of these tricks was called fogweaving, a binding-spell that gathers the mists together for a while in one place; with it one skilled in illusion can shape the mist into fair ghostly seemings, which last a little and fade away. The boy had no such skill, but his intent was different, and he had the strength to turn the spell to his own ends. Rapidly and aloud he named the places and the boundaries of the village, and then spoke the fogweaving charm, but in among its words he enlaced the words of a spell of concealment, and last he cried the word that set the magic going.
