Initials shown. Four Horsemen Entertainment's team page places a portrait directly with its Sean Jaffe biography and explicitly identifies R.M. Sean Jaffe as a novelist, screenwriter, and game designer who worked with Eschaton Media. RPGnet and Nerdy City's official product page independently connect the same extended credit to Chronos and ReMemorex. The team page is marked All Rights Reserved and gives no photographer credit, so permission is required. Open the documented source.
