Apocrypha
The Apocrypha is a sacred document at the Stygian Crossroads in Mhaldor. Its study is a requirement for most Mhaldorian novices. It further details the actions and methods of worship for followers of Evil, beyond the Seven Truths. Though it references worship to Lord Sartan, its words remain relevant to the worship of the Lords of Evil
Page one of the Apocrypha simply states:
And in that day, atrocity shall overtake the world and all shall walk in fear.
This is followed by six chapters, including The Song of the Lord, Prayer of the Lord, Procreation of the Unholy, The Missionaries of the Lord, Covenant of the Lord, and Obediance to the Lord.
One mystery of the Apocrypha that has caused much debate by scholars of Evil is the missing sixth verse in Chapter Six.
