From the introduction:
The most devout priests among Khayne’s worshippers revel in shed blood, whether from their own flayed backs and lacerated limbs or from tortured victims consumed by diabolical rites of sacrifice. Cannabilism is encouraged, and his apostles rouse a bloodlust as primal as the deity it is inspired by. No true minister of the dark god’s teachings considers his own blood too sacred to spill, and their traditions of mutilation extend far past the shallow waves cast in the histories of Exodus by his best remembered devotees. While mass sacrifices and other common rites of devotion are better known, the Scepter of Perpetual Sacrifice represents the crowning achievement of Khayne’s earliest zealots. This ancient weapon is emblematic of and testament to the Blood God’s primordial power, with its most potent abilities fueled by the wounds it inflicts on both victim and wielder.
