All knowledge is sacred, but it should not be secret. - Susan Cooper

Will saw the cruelty now as the fierce inevitability of nature. It was not from malice that the Light and the servants of the Light would ever hound the Dark, but from the nature of things.

The Land is neither of the Dark nor the Light, nor ever was. Its enchantment was of a separate kind, the magic of the mind and the hand and the eye, that owes no allegiance because it is neither good nor bad. It has no more to do with the behaviour of men, or the great absolutes of the Light and the Dark, than does the blossom of a rose or the curving leap of a fish.

Each wave of men in turn grew peaceful as it grew to know and love the land, so that the Light flourished again. But always the Dark was there, swelling and waning, gaining a new Lord of the Dark whenever a man deliberately chose to be changed into something more dread and powerful than his fellows. Such creatures were not born to their doom, like the Old Ones, but chose it.
