She is the matriarch of the Black family and has a short temper. If you’re on the family tree, dating someone on the family tree or causing trouble for someone on the family tree you will hear from her. Walburga sends a large number of Howlers to her family members when she perceives them as getting out of line, and she likes to know everyone’s business.
Currently her marriage to Orion is faltering due to the problems they’ve had with Sirius and she is growing more and more agitated about what she might have to do.
There’s more information about her on her journal, but I’d love some plot and also to work out her relationships with her children and family.
