Tanya Matthews was a half-blood witch, owner of the Blue Sceptre on the corner of Diagon Alley and Knockturn Alley. The staff of Hogwarts frequented her pub on the weekends. Her familiar, a silver falcon named Zarath, was the pub's mascot.
Her mother, Corrine Matthews, was a Muggle curious about the wizarding world. A good friend of Tanya's during her school years, Calista Malithorp, was a pureblood and a mouse animagus. Both attended Hogwarts and were Sorted into Gryffindor.
