Sabertooths of Blackburrow Faction
 

I lowered my SabertoothsofBlackburrow faction to the bottom by fighting mobs. After wards I did The Jaggedpine Crook quest and it lowered my faction but did not say it was already at the bottom. This probably means there is more than one "SabertoothsofBlackburrow" faction in the database. Not a big deal since the mobs are on the prevalent one.
