The cultivators from this sect were known for their cruel methods and all of them had slaughtered numerous others that it may actually be the very requirement to join Blacksoul Society. They believe themselves to be the most savage entities in existence. They only have one Dao Realm Patriarch, a 3-Essences Dao Lord.
They use countless souls to augment their powers and it so happens that one such soul that they trapped was that of Chu Yuyan's. This sect was then subsequently single-handedly eradicated by Meng Hao, meting out a heavenly punishment.
