A contrary power, dubbed the True Power, is associated with Shai'tan.
Channelers can direct the Power toward a desired purpose by creating one or more "flows" of the One Power and constructing "weaves" of these flows.
The Wheel has seven spokes, each representing an 'age' or phase of history, and rotates under the influence of the One Power, which flows from the True Source composed of male and female halves (saidin and saidar).
Humans who can use this power are called 'channelers'; the principal organization thereof in the books are the Aes Sedai or 'Servants of All'.
Nynaeve al'Meara, the village wise-woman, later joins them. The first novel depicts their flight from various agents of the Shadow and their attempts to reach the Aes Sedai city of Tar Valon.The One Power consists of male and female halves called saidin (accessible by men) and saidar (accessible by women).The One Power is further divided into the 'Five Powers': Earth, Water, Air, Fire, and Spirit.In the aftermath, the women Aes Sedai re-organize society, and nullify male access to the Power.Two subsequent events are important to the novels' principal story: the "Trolloc Wars", in which servants of the Dark One foment a continuous war for several hundred years; and the "War of the Hundred Years", a devastating civil war succeeding the fall of a continent-spanning empire ruled by the "High King", Artur Hawkwing.
