Your character can be either a member of the order of True Levites, or a true-blooded Canaanite. Both sides are responsible for atrocities and are morally grey. One side is not 'good' and the other is bad. However, Canaanites are required to be cannibals to survive. Also because of the nature of this being a large-scale global conspiracy, you should take into consideration that your character should be fairly influential/powerful, otherwise, how will they realistically influence the story?
Noah, son of Lamech, cursed the second son of his second son for a crime lost to the annals of history. These people came to be known as the Canaanites. The sons of Canaan. They were cursed to live lives of torment and hatred for a crime committed millennia ago by a common ancestor.
Homo Sapien Khanaan is a peculiar human subspecies originating from the Levant, having co-existed and been subservient to the Semitic peoples of old. However, over generations, they grew hateful of Shem's God. Yahweh. In the second temple era, an underground group of the dwindling population of Canaanites turned to the dark god Moloch for his favour. This ritual became known as the first supper. The boon granted to them for their heinous deeds? A child born tainted with the blood of Canaan is blessed with the burden of a deep-ceded desire for the flesh of their peers. This hunger provides them with abilities incapable of the sons of Shem of Japheth. With this boon, the Cabal was able to live to an age not seen since the antediluvian period and the days of Methuselah.
Using the powers bestowed upon them by their forbidden gods, this secret group began to accumulate knowledge and power. They were some of the first scientists, philosophers, and artists. They had a vast administration keeping track of the genealogy of all Canaanites. Using their influence to hide their growing population and vast human farms.
However, they couldn't hide forever. Someone noticed something was off. The methods of their reveal are another of history's great mysteries. But an ancestor of Levi, a devout Kohen priest would discover the Canaanites' generations of heresy and debauchery. He continued to investigate, not yet noticed by the watchful gaze of the Cabal's administration. He would secretly spread the word among certain devout Kohen, of the purest blood and most pious nature. This group would become known by the few aware of their existence as the 'True Levites' and they would hide in the shadows, planning their first actions against the Canaanite superpower.
When the time was right, they attempted to tear away the veil, revealing to the Israelites the cannibal enemies hiding beneath their noses. the True Levites had managed to capture fragments of the Codexes detailing Canaan genealogy. Using this information, they provoked a violent and bloody all-out war, ending with every single one of the names listed in the Codex fragments being purged from history.
Unfortunately, this would prove to only be a small percentage of the Canaan population. Canaanite elders used the first Levitic-Canaan war as a lesson. Before promptly erasing all knowledge of it happening from all records nigh the Levitican records and their own. They soon instituted strict population control to prevent the rediscovery of the population. And secondly, they began developing a new method of feeding their population.
Despite this still happening in the middle Roman era, the Canaans used their highly advanced and secretive technology to crossbreed human livestock and animal livestock to create monstrous and horrific animal-human hybrids. These heretical creatures had the intelligence of livestock, and were almost undetectable from their normal animal counterparts, except for subtly closer human features. This human-animal livestock was then disseminated across the globe and is prolific across the entire world. Levitic estimates believe that they are outbreeding regular livestock and currently comprise nearly 80% of the current livestock population and will likely completely replace animal livestock within the century. Because of the integration of their food source, Canaans were then capable of almost indistinguishably integrating into normal society.
From then until today the True Levites have gone back to working in the shadows, attempting to route out the despicable blight on humanity that is the Hidden Nation of Canaan and its monstrous citizens, Homo Sapiens Khanaan. It is believed by our Levite Knights that many powerful and influential historical figures were Canaanites or put into power by the Canaanites to help them achieve their goals.
For example, it is believed Hitler, and the entire Nazi regime was orchestrated by them. As well as almost every notable scientist ever. Archimedes, Einstein, Newton. Almost every world leader is believed to be Canaanite, and if not they are a Levite. The entirety of the organisation of Free Masons is Canaanite, it is believed.
