This sect followed the Apostate Menkirafed, who was executed and dismembered as a heretic by the old establishment of the Dor-en-Sann Empire. His true origins are obscure, but he was probably born in a remote village of the old River States, somewhere between the cities of Delan and Seqal, around 2980 HM. At a young age he joined an extreme desert cult and dwelt with them for many years on a rock above the salt bleds of Mangasor, where the Great Lake springs out of desert once every decade. He experienced their mysteries and religious ecstasies, brought about by certain rock funghi, and studied hundreds of religious texts from all faiths of the EnSanni Empire. But rather became a zealot, he became increasingly disillusioned with and critical of these hermits. Their religious hysteria eventually led to him rejecting their beliefs altogether, and he instead came to believe that deities were in fact the creations of society and the imagination.

He preached throughout the towns and cities of northern Deltirot that there was in fact no true God or Goddess. He preached that there were indeed spirits in the world, but they were morally and intellectually inferior to Man and not deserving of worship. All deities that demand worship from Man, he preached, were merely selfish and self-serving spirits. Mankind was better served by ignoring their petty demands, so that they would wither away to leave a world of reason.

Instead, he preached a pantheist philosophy of universal human divinity, based on a code of ethics that promoted humility, self-effacement, charity and non-violence. His followers stirred up political opposition in Deltirot to the Empire, and he was held as an ideal of rationalism in the face of EnSanni superstition and commercial idolatry. In the 3020s HM, hundreds of temples were smashed and burned in his name. He personally preached opposition to violence and condemned those who took violent action in his name; which was perhaps the reason his supporters did not rush to his aid when he was finally arrested by the authorities in 3028.

He was imprisoned, and after a brief show-trial in which he was given little opportunity to speak, he was condemned to death and hanged. There are several conflicting stories, which have led to myths and ceremonies upon which his modern cult is based.

According to the first account, after his body was cut down he was dismembered by the authorities in front of a baying crowd. The crowd tore his body into scraps, and some even devoured his flesh in their crazed intensity. This story was circulated by the EnSanni, as an example of the punishment meted out to heretics.

The most famous legend, enshrined in cult texts is that after his trial and execution, in which his followers had made no attempt to defend him, his closest adherents were all arrested. Ten of them were locked in a room, with the torn and rotting corpse; an act by the authorities meant to terrorise them and demonstrate the horrors to come. The authorities intended stuffing the body, and parading it in victory around cities where the Cult had gained a hold.

The followers were desperate to prevent this, but had no means of protecting the body of their fallen leader. So, with great horror and solemnity, they devoured the flesh of their leader, so that there would be no remains for the authorities to exploit.

The cult grew exponentially after Menkirafed's death, infiltrating the Deltiriot government and causing a political and religious schism from the Empire. Gaalkesh threatened war against Deltirot, but by this time the Empire was too decadent and weakened by famine in the homelands to attempt a lengthy campaign in the far south.

Over the next century the cult gained footholds in many Imperial cities, and enclaves were persecuted by city governments. Cultists even aided the Prophet Therion during his conquest of Orror, supplying military intelligence and even carrying out acts of sabotage. However, in the years after the foundation of the new Church-State of Orror, the memory of Menkirafed was hijacked by the church. He was incorporated into Therist doctrine as a precursor of the Great Prophet. Based on these new texts and the obvious divinity of the Prophet, many Deltiriot cultists were converted to the new religion. Those that clung to the old tradition were persecuted, sometimes by their own family members; persecuted and ridiculed for their adoration of the gallows, symbolising the death of their prophet, and their ritual of mock flesh-eating.

Today they exist as an independent underground sect, existing in many Orroran cities. The cultists are forced to practice in secret, further reinforcing the suspicion with which they are viewed by Orroran society. Many cultists fled abroad but the faith never spread much beyond its root community. Today there are refugee enclaves in many large port cities around the world: in Harlon in Harthera, Marr Sirque in Anarthis and Belisan Freeport in Anrette.
