It takes place during the Ottoman incursions into Europe in the 16th Century (specifically between the Battle of Mohács and the first Siege of Vienna) and revolves around Knight of St. John Gottfried von Kalmbach and female swashbuckler Red Sonya of Rogatino, who strike up a partnership after surviving the fall of Mohács and trying to escape from the feared Turkish commander Mikhal Oglu, also known as the Vulture, sent by the Sultan to bring him Gottfried's head.
Sonya is notable for serving as the blueprint for Red Sonja, who was created by Roy Thomas for the Conan comics. She debuted in the 1973 Marvel-published Conan the Barbarian issue #23 which adapted The Shadow of the Vulture and setting in Hyboria instead of our Earth, with Vienna being replaced by the city of Makkalet, Gottfried replaced by Conan, Sonya by Red Sonja, Suleyman by Yezdigerd the Turanian Emperor. Mikhal is the only one left unchanged except he is Turanian rather than Turkish.

- Cain and Abel: Red Sonya's sister is none other than the Sultan's favorite concubine Roxelana (also known as Hurrem Sultan). While they are in the opposite sides of the war with Sonya supposed to be the good one and Roxelana the evil one due to being the Big Bad's Dark Mistress, we never really see how Roxelana feels about her sister, while Sonya refers to her in a very insulting way everytime she talks about her and is the one most eager to kill her:Gottfried: Why did you wish for the Sultana Roxelana for a target, my girl?Sonya: Because she's my sister, the slut!
