The 9th iteration of Space and Humanity was a book focused on the subject of starship design during the era known as the High Republic Era. It was both authored and released by Mr. Carl, who holds the position of chief engineer at Star Bay Shipyards. In this particular version, Mr. Carl refined the internal arrangements within starships.
During the year 200 BBY, Jedi Master Mostima and her Padawan Sean were dispatched on a mission directed towards the Aakaash system. Following their separation resulting from an attack, Sean aligned himself with the Silver Knights, a local mercenary organization under the leadership of Li Yu. Upon Li questioning Sean regarding the young boy's impression of his battleship, named the Silver Dawn, Sean pointed out its apparent design adherence to the principles outlined in the 7th edition of Space and Humanity. Subsequently, the Jedi suggested improvements through retrofitting to align with the 9th edition, highlighting its enhanced interior space optimization. This prompted the mercenary captain's anger, who revealed his unawareness of Mr. Carl's new edition. Furthermore, Li indicated his financial constraints, rendering him unable to afford every edition, let alone the modifications needed to conform his ship to each new technique.
The 9th edition of Space and Humanity received a mention in the 2020 Chinese web-novel, The Vow of Silver Dawn, penned by "His Majesty the King." Within the novel, the book's title was represented using Simplified Chinese characters, specifically "第9版."
