Geas

Geas is an archaic Forerunner term that refers to a generations-long genetic command imposed on an organism or species. Under the influence of a geas, an organism can be given a set of subconscious orders that will be passed on to their children, in some cases lasting several generations. Only highly skilled Forerunner Lifeworkers were capable of creating a geas.
In approximately 100,300 BCE, Bornstellar-Makes-Eternal-Lasting speculated that The Librarian had imposed a geas on the human race. Forerunner students of the Mantle also hypothesized that the Precursors may have imposed a geas on the Forerunners themselves.Halo: Cryptum, page 49
==Trivia==
*The term comes from the Irish/Scottish Gaelic word geas, which is a curse, spell, or vow. 
*The fact that the specific power of Forerunner Geas is a subconscious order, or command, is a reference to Code Geass, where the main character Lelouch has the power to give orders to anyone who meets his gaze, also a genetic power passed down for generations.
