Aes Sedai
In "The Wheel of Time" universe, the "Age of Legends" is the name given to the previous Age: In this society, channelers were common and Aes Sedai – trained channelers – were extremely powerful, able to make "angreal", "sa'angreal", and "ter'angreal", and holding important civic positions. The Age of Legends is seen as a utopian society without war or crime, and devoted to culture and learning. Aes Sedai were frequently devoted to academic endeavours, one of which inadvertently resulted in a hole – The Bore – being drilled in the Dark One's prison. The immediate effects were not realised, but the Dark One gradually asserted power over humanity, swaying many to become his followers. This resulted in the War of Power and eventually the Breaking of the World.
