Of my deamon princes she probably has the least amount of solid lore right now sadly. All i am solid on is that she works with my Nurgle Deamon Prince out of boredom and her own enigmatic plans. (Ie they like the same poor guardsmen and working with her means she can initate plans to win him).
I havent really pondered her backstory much beyond that. I guess she usually gets into contracts with mortals to take their souls and add them to the blue slime you see. She can then do some fate weaving with those souls and the knitting needles.
