And remember we are talking about a comic book, not "real characters" : a "simple" family problem, like an unexpectedly super powered teenager trying to prove her worth by defeating her super heroic cousin, can be the beggining of an unending feud, with the Matriarch always trying, again and again, from comic to comic, to finally get rid of this cousin that keeps putting her down. While Tachyon doesn't know if she should put her in the Block, slap her, or hug her.
Especially because the Matriarch, angsty as she is, is very powerful- if she ever puts her mind to it, in the comics, she could become one of the most dangerous would-be Master of the World with her terrifying armies of birds obeying her every thought and desire... Seeing how "dark" all villains/story lines in Rook City are, I think her stories are probably more horrifying than what we expect, and the fictional "reader" far more impressed by her villainy than we are. After all, she is inspired by a movie where birds kill, maim, and destroy whole villages.
She reminds me of one of the stories in the Grey Mouser/Fafhrd cycle, where a bird priestess used her control of birds to terrorize Lankhmar, and women, fearing to be disfigured,put cages of their head to protect their faces and jewelry.
Finally - the game reflects the "comics", and she is a difficulty 4 villain, as dangerous as the Chairman and his organization. I take this as a clue that she must be a terrifying villain in the comics. The card "Carrion Field " may very well be the results of her actions...
Edit : I just had this strange idea - what if, after Vengeance, there was another "villain team" expansion about the mysterious Undead Poets Society ?
Another strange idea : you know who would be a great "guest writer" for a Matriarch mini-serie ? Neil Gaiman !
