Sarah Cawkwell
Sarah Cawkwell is currently the only female novellist in the sausage party that is the Black Library.
The running gag is that she is a hot, sexy, goth chick, and therefore not real. This is because the only women who go into a Games Workshop are the ones that fa/tg/uys dream up in their heads. She's actually a rather charismatic and regular looking human being, who has a blog, even though there are No Girls on the Internet. She wastes a lot of her time playing Morepigs, apparently.
She apparently researched Norse Sagas while writing Blood Raven, as the entire story is basically Valkia teaching her fellow Norscans a ritual torture exactly similar to the real-life "Blood Eagle" present in Norse sagas. This makes sense because the Warriors of Chaos are evil Chaos Vikings anyway, and because this ritual was already in Wulfrik. Also, Khorne apparently thought it up and gave it to the Norscans. It must be reiterated that this short story is named after the procedure detailed in the Norse sagas and NOT after a certain chapter of BAWLD AND FEWLISH Space Marines.
She's apparently visited this wiki a few times. Probably found it after Googling herself.
Not Aaron Dembski-Bowden or Graham McNeill. Certainly not Nik Vincent, because that would mean that she'd be married to Dan Abnett.
No one dares to make the obvious joke. NO ONE.
