Children of Cain

The Children of Cain were a collective of individuals that followed the teachings of Cain, the son of Adam and Eve. They are the oldest known precursors to the Order of the Knights Templar.

Sometime after the Toba catastrophe and the Human-Isu War ended, Cain killed his brother Abel to acquire the Apple of Eden their parents previously possessed. For his crime, Cain was brandished with a red cross. The Children of Cain named this cross the Mark of Cain and, millennia later, it would be adopted by the Knights Templar as their insignia.
