Cain

Cain and Abel, according to the Bible, were the first two sons of Adam and Eve (Cain being the eldest). According to the Bible, Abel had pleased God with his sacrificial offering while Cain had not. This 'pleasing God' may simply be a coded way of saying Abel had or was given a Piece of Eden. Cain murdered Abel to retrieve Abel's Piece of Eden from himself. It is unknown what happened then, though the bible states a cursed mark was placed upon Cain, known as the "Mark of Cain". Knights Templar eventually used this mark as the symbol for themselves, probably after they became atheist. Subject 16's glyph sequence confirms these details, although it does no continue events out beyond the biblical account. How long ago these events occurred is unknown, though if the Bible is to be believed, he and Abel were the sons of Adam and Eve, placing the event of Abel's murder a generation after Adam and Eve.

Subject 16 also references quotes the from the Mormon and Latter Day Saints movement's "Pearl of Great Price" scultpure. The semi hidden message "Templar texts adapted by Mr. Smith" written in Morse code in a glyph sequence, implying that the Mormon or LDS version of Cain and Able is more accurate, or at the very least least, an accurate reflection of the Templars version of events. The relativity unique title of "Master Mahan" is mentioned as the title Cain gave himself. The meaning of the term is unclear, and it does not seem to occur in other versions of the story.
