As the article mentions two Laurels and a Knight (working as an apprentice) were involved on this project, here is a short description of who they are within the Society for Creative Anachronism . The Order of the Laurel ("Laurels is awarded for skill in the arts and sciences. the Order of Chivalry (Knights) is awarded for skill at arms (hence the reference of Sir Peregrine as "the muscular knight with stamina and drive for dull repetitive hammering")

Individually, these "peers" are expected to provide leadership and mentoring to others through continuing research, teaching, and encouraging other artisans and/or fighters.

The SCA (Society for Creative Anachronism) is a non profit, world wide Historical reenactment organization founded in 1966. You can check out this Wiki Link for a general, succinct, description or go to the Official website for more in depth information.
