Mark Lardas has always been fascinated by things related to the sea and sky. From building models of ships and aircraft as a teen, he then studied Naval Architecture and Marine Engineering, but his interest in aviation led him to take a job on the then-new Space Shuttle program, where he worked for the next 30 years as a navigation engineer. Currently he develops commercial aircraft systems as a quality assurance manager. He has written numerous books on military, naval or maritime history. Edouard Groult grew up inspired by watching historical documentaries with his father and developed a fascination for historical and fantasy art. Following art studies in both Paris and Belgium he worked as a concept artist in the videogame industry and in recent years has also undertaken historical commissions while working as a freelancer for historical magazines. He lives and works near London.
