In the Volsunga cycle, Gram is the reforged sword with which Sigurd slays the dragon Fafnir — inside an arc whose prince IS a Norse dragon (Niddhoggr) and whose lore runs on Norse names (Ragnir/Ragnarök, Nibelheim/Niflheim, Thorheim, Gungnir). A named dragon-slayer prop on-page while a dragon dominates the battlefield is a loaded Chekhov blade. Watch: the wielder’s identity; whether Gram is ever aimed at Loki. (Distinct from Chief Jarul’s Sword Excalibur And The Draw-The-Sword Legend — different blade; part of the Elbaf named-blades cluster.)
