|“|| Am I my brother's keeper?|
- Cain's answer to God
In the mytho historical accounts of Judaism, Christianity and Islam, Cain ('Kayin' in ancient Hebrew and 'Qabil' in Arabic) was the eldest of the sons of Adam and Eve and the first murderer of the world.
Cain and Abel
According to Genesis, following humanity's fall, Adam and Eve had two sons: Cain and Abel. God showed greater favor to Abel, a shepherd who had sacrificed his best lambs to God, while Cain was a farmer who only offered ordinary specimens from his crops. God thus accepted Abel's offering while rejecting Cain's. In envious rage, Cain murdered his brother Abel in an open field. Later, God tellingly asked Cain where his brother was. In a deliberate act of defiance, Cain answered: "Am I my brother's keeper?" Upon this, God decreed the ground would no longer produce for Cain, and that he would exist in a state of perpetual wandering upon the Earth. Cain responded that his punishment was too great, and that anyone meeting him would kill him. God thus marked Cain, stating that any who harmed him would have sevenfold vengeance taken on them. Cain then departed in exile, heading to the Land of Nod, to the east of Eden.
Cain and Kane
With the quasi-religious nature of the Brotherhood of Nod, one can't escape the similarity between the names 'Cain' and 'Kane'. While it could be a coincidence, Nod's leader may be using this ancient parable to further his image as a "prophet" figure. However, there are many in the Brotherhood who passionately believe Kane is indeed none other than Cain/Kayin/Qabil. These Nod followers contend it is this which renders Kane seemingly immortal, and that he is now the sole person left on Earth to have seen, and spoken to, God. This would explain Kane's unusually deep understanding of the nature of man and the world, his apparent agelessness, as well as how he repeatedly survives fatal injury.
Nod artifacts discovered inside a cavern complex deep below an ancient Temple of Nod in Egypt indicate possible links between the Brotherhood and this religious tale. Whether Nod is truly thousands of years old or they have merely named themselves after the 'Land of Nod', to which Cain was banished after the murder of Abel, is unknown. Nothing has been truly confirmed either way on this matter, since the Temple where the artifacts were found was completely annihilated by the detonation of a nuclear device. However, Kane's original second-in-command during the First Tiberium War, Seth, is another reference to Cain, as the third son of Adam and Eve was also named 'Seth'. Likewise, the Marked of Kane faction within the Brotherhood clearly draw their moniker from the biblical "Mark of Cain".
