Lord Lythys Blackstone (aka Lythys the Sorrow, Lythys the Loving, and the Spoiled Sorrow) is the descendant of an illicit relationship between the noble houses Prynn and Premlock. Lythys is one of seven Blackstone children, all of which are horrible people by reputation except one.
Lythys is no true Lord in the sense that he holds no lands or authority. He merely lives off of the two noble families from which he has descended.
After turning down Lythys’ offer for employment, the Sorrow indicated the group could find him usually traveling between Tidalpool and Blackscale Deep. After murdering Boleo and his father, the Sorrow and his men took off in the middle of the night.
