Life
John Harper is an American game designer and graphic artist based in Seattle, Washington, who has published much of his work under the studio name One Seven Design. Little about his early life is on the public record, and no reliable source gives his birth date. His design reputation grew in the independent roleplaying community of the late 2000s, the scene that had formed around the Forge forums and games such as Vincent Baker's Dogs in the Vineyard. He is unusual in that community for doing his own illustration and graphic design. The cover of Blades in the Dark is his.
Work
Harper first became widely known for small games he gave away. Lady Blackbird (2009) is a complete adventure in a few pages: an imperial noblewoman flees an arranged marriage aboard a smuggler's skyship, which is promptly captured, and the players begin in its brig. It comes with pre-generated characters and quick-play rules for a no-prep game of one to three sessions. It won the 2009 Indie RPG Awards for Best Production and Best Free Game, and critics have since listed it among the seminal indie games of that era, alongside Dogs in the Vineyard and Apocalypse World. Lasers & Feelings (2013), based on songs by The Doubleclicks, fits a whole science-fiction RPG on one page, with a single stat that runs from logic to passion. It has been widely hacked into other one-page games. World of Dungeons (2012) distilled Apocalypse World's core mechanic into a quick-play dungeon crawler written as a companion to Dungeon World.
His other designs include AGON, a game of Greek heroes facing trials set by the gods, which he revised with Sean Nittner in a second edition published by Evil Hat Productions in 2020. Its Paragon system is available under a Creative Commons license. He has also made smaller games such as Ghost/Echo, The Mustang and Bootleggers.
His major work is Blades in the Dark. Set in Doskvol, a sunless, lightning-fenced industrial city of ghosts, vampires and gangs inspired by Victorian London and Gothic fiction, it casts the players as a crew of scoundrels rising in the underworld. Harper took the Apocalypse World approach of playbooks, fiction-first actions and partial successes, and built new systems around it. Players roll pools of six-sided dice and take the highest; they can take on stress to push themselves or resist consequences, at the risk of trauma. The crew has its own playbook, reputation, turf and heat. Progress clocks, circles divided into segments, track everything from alarms to gang wars. Its best-known idea is the flashback: players skip the planning session, the game master opens a score just as it goes wrong, and players spend stress to reveal preparations they "already" made. Between scores comes downtime, when characters heal, work on projects, and indulge the vices that relieve their stress.
The Kickstarter launched on March 9, 2015, with a $7,500 goal. It was funded within a day and closed on April 9 at $179,280 from 3,925 backers. Early-access digital versions went on sale in 2016, and the finished game, published with Evil Hat Productions, was released on January 30, 2017. It won the 2015 Golden Geek RPG of the Year and the 2016 Indie RPG of the Year before its final release. In December 2017 Harper released a Creative Commons System Reference Document so anyone could build on the "Forged in the Dark" system. In 2024 he released the expansion Blades in the Dark: Deep Cuts, which Polygon named one of the best tabletop RPG books of the year.
Legacy
Forged in the Dark became one of the major families in narrative game design alongside Powered by the Apocalypse. Evil Hat published Band of Blades and Scum and Villainy, and by April 2023 itch.io listed more than 300 products tagged Forged in the Dark. Blades' flashbacks, stress and clocks have spread well beyond its descendants. Progress clocks in particular have been widely borrowed by designers and game masters working in other systems.
Harper's career also shows how independent RPGs were made and sold after 2010: free and pay-what-you-want PDFs to build an audience, crowdfunding to pay for a major book, public playtesting, open licenses to encourage imitators, and itch.io as the main storefront. The television deal announced in 2021 suggests that Doskvol may eventually reach an audience beyond the gaming table.
