A beast pedigree? Yes, come to think of it, Ja'Weer is from a long line of trained house slaves. I have his pedigree here. It could be a forgery, but I know of the family, and it all seems to line up. The Khajiit Jar'Jo-Zhid didn't come with a pedigree, so he must be a first-generation slave, probably captured as a freeman in war or enslaved as punishment for a crime.

A beast pedigree is a document which details the lineage of multi-generational beast slaves. It can serve both to prove the legitimacy of the slave's upbringing and to drive up a slave's value by corroborating descent from a highly sought-after familiy. I will have the muthsera know that I can perfectly trace my lineage back to the Tul-Kustha-Meer, one of the oldest and finest families. They say my ancestors served even Lord Vehk himself, long ago. You will find no more competent and loyal creature than I.
