Though the men of the Seven Kingdoms might call them the children of the forest, Leaf and her people were far from childlike. Little wise men of the forest would have been closer. They were small compared to men, as a wolf is smaller than a direwolf. That does not mean it is a pup. They had nut-brown skin, dappled like a deer’s with paler spots, and large ears that could hear things that no man could hear. Their eyes were big too, great golden cat’s eyes that could see down passages where a boy’s eyes saw only blackness. Their hands had only three fingers and a thumb, with sharp black claws instead of nails.
And they did sing. They sang in True Tongue, so Bran could not understand the words, but their voices were as pure as winter air. “Where are the rest of you?” Bran asked Leaf, once.
“Gone down into the earth,” she answered. “Into the stones, into the trees. Before the First Men came all this land that you call Westeros was home to us, yet even in those days we were few. The gods gave us long lives but not great numbers, lest we overrun the world as deer will overrun a wood where there are no wolves to hunt them. That was in the dawn of days, when our sun was rising. Now it sinks, and this is our long dwindling. The giants are almost gone as well, they who were our bane and our brothers. The great lions of the western hills have been slain, the unicorns are all but gone, the mammoths down to a few hundred. The direwolves will outlast us all, but their time will come as well. In the world that men have made, there is no room for them, or us.”
