Gram was the sword the hero Siegfried used to slay the dragon Fafnir in the Nibelung myth, a sword capable of cleaving through a solid iron anvil without problem. Since then it's been associated with the ability to easily slay dragons.

Some actually consider it the norse counterpart to Caliburn, because Sigurd, Siefried's father pulled it from an enchanted tree and thus was considered a king.
