The origin of Red Sonja, "The Day of the Sword", first appeared in Kull and the Barbarians issue 3 by Roy Thomas, Doug Moench and Howard Chaykin, and was later redrawn by Dick Giordano and Terry Austin for The Savage Sword of Conan, issue 78.
Red Sonja lived with her family in a humble home in the Western Hyrkanian steppes. When she had just turned 17 years old, a group of cruel mercenaries killed her father Ivor, her mother and two younger brothers and burned their house and all their possessions. She survived but was raped by the leader of the group. Answering her cry for revenge, the red goddess Scathach appeared to her, and instilled in her incredible skill in the handling of swords and other weapons on the condition that from thenceforth she never lay with a man, unless he defeat her in fair battle
