Geas was an archaic Forerunner term that referred to a generations-long genetic command imposed on an organism or species. Under the influence of a geas, an organism could be given a set of subconscious orders that would be passed on to their children, in some cases lasting several generations. Only highly skilled Forerunner Lifeworkers were capable of creating a geas. Forerunner students of the Mantle also hypothesized that the Precursors may have imposed a geas on the Forerunners themselves.[3]
The Librarian imposed a geas upon several human family lineages, including those of the Florian Riser and chamanune Chakas, who were imprinted with a drive to pass the defenses surrounding the Didact's Cryptum at the Djamonkin Crater. Their geas also included songs which served as codes to open the Cryptum,[4] as well as deep genetic memories of their ancestors who fought in the human-Forerunner wars,[5] including the long-lost secret for stopping the Flood.[6]
