The heart of the forest is much darker than the edge, but because the trees are just as white, and the leaves just as pale, light is reflected the same way here. This means the heart of the White Forest is still much brighter than a normal forest, and there is ample light to see by. There is a lake here, and the only creatures that live this deep in the forest are songbirds of brilliant color, and the First Pack themselves. Only the chosen wolves ever see the heart of the forest.
