Iron Firmament is a series of alternate future/universe skins in League of Legends. Set in a dystopian galactic future, it features champions augmented by exo-suits with godlike abilities.
A war-torn galaxy attempts to rebuild, but old wounds remain. Bounty hunters and corporate agents have filled the power vacuum, some piloting dangerous combat exo suits with godlike abilities. In response, megacorporations leverage private armies to enforce their will across the far-flung colonies of space. War never dies; it only changes battlefields.
Iron Firmament officially encompasses four skin lines: Dreadnova, Eternum, Steel Legion, and Steel Valkryies.
