Elden Ring’s story is often attributed to two people: FromSoftware president and creative director Hidetaka Miyazaki, and A Song of Ice and Fire author George R.R. Martin.

While Miyazaki is credited as the creative mind behind its dense lore and high-fantasy setting, a game as big as Elden Ring had a huge team working on it, and a lot of its story was crafted through gameplay and environmental world-building rather than through a more traditional narrative. Plus, there’s the whole Martin thing.

I’ve seen a lot of misunderstandings and confusion out there in regard to how much Martin contributed to Elden Ring. One review I read mentioned the author several times and even said the game features “Thrones-level twists,” as if Martin had written out each plot point himself.

Polygon combed through a ton of writing about the game, including posts from Martin’s blog and interviews with FromSoftware team members, to put together a better picture of his contribution.

Martin wrote in a post on his blog that the team had reached out to him to create a “deep, dark, resonant world to serve as a foundation” for the game, including the “imaginary history.” While the Game of Thrones au
