Forerunner mutation

Mutation was a Forerunner term referring to customized biological maturation to new forms or rates. The process was typically performed between two to five times over the course of a lifetime. In society, a Forerunner's mutation determined the individual's place within their family, Maniple, or guild and was always patterned after the individual's mentor, typically but not always the parent.

Typically, a mutation was a slow, gradual process, with the changes appearing over a period of several years. "Brevet mutation" was a term used to refer to the undertaking of risky, ad hoc mutations that carried higher risk of complication. This type of mutation was typically performed by Warrior-Servants during wartime. The Didact provided a brevet mutation for Bornstellar Makes Eternal Lasting, whereas the Didact's brevet mutation had been performed by the Confirmer thousands of years earlier.

The mutation ceremony itself was a highly ritualistic process. It had to be performed under the direct light of stars, or a close approximation, such as a projection of the exterior inside a starship. The individual undergoing the mutation, as well as their mentor, had to be completely naked during the process. A mutation was said to be painful, but anyone present was not permitted to respond to anything else than requests for water to drink. First, a column with small spherules outlined and scanned the Forerunner being mutated, and was connected to the mentor during the process. The spherules contained the various chemicals involved in the mutation, and the mentor's genetic imprint was supplied through the connection. A specific ritual litany was recited by the mentor during the mutation. It was expected for one to be disoriented, hungry and thirsty following a mutation. With normal mutations, it would take several years for the changes to take effect, while in brevet mutations, they would appear within a matter of days.
