The Legend of Heroes, known in Japan as Eiyū Densetsu, is a series of role-playing video games developed by Nihon Falcom. First starting as a part of the Dragon Slayer series in the late 1980s, the series evolved into its own decade-spanning, interconnected series with fourteen entries, including several subseries. All games in the franchise released since 2004 are part of the Trails subseries, known as Kiseki in Japan. The most recent entry, The Legend of Heroes: Kuro no Kiseki II – Crimson Sin, was released in 2022.
A Dragon Slayer: The Legend of Heroes original video animation anime was released in 1992, the same year that Dragon Slayer: The Legend of Heroes II was released, loosely based on the story of the first game. In 1997, it was dubbed into English by Urban Vision and was released onto VHS in North America.
In 2009, three volumes of a Trails in the Sky manga were published in Japan by Kadokawa Shoten, which was followed next year by a sequel, Trails from Zero: Pre-Story, published by ASCII Media Works. Two original video animation anime episodes of Trails in the Sky were respectively released in October 2011 and January 2012. The Legend of Heroes: Trails of Cold Steel – Northern War, an anime television series by Tatsunoko Production and set in the Trails universe, began airing in January 2023.
