Let me tell you what I know about "the Seven," those Tevinter magisters said to have entered the Golden City long ago. Each was a high priest to one of the Old Gods. Each came to the ritual shrouded in secrecy, hiding their true name even from each other. They were competitors, you see. The Old Gods told them they would break into the Golden City and usurp the Maker's throne... but only one of them could sit on that throne. Each assumed a title related to their role in casting the ritual. Some texts claim they had a leader: the High Priest of Dumat, called "Corypheus." He did not rule this group, but instead conducted it, coordinating their efforts to achieve a magical feat never since replicated. They breached the Fade, walked physically in dreams, and changed our world forever.
