I also think there is something to the name of the weapon. For example, the Drake Sword description states: ''This Sword, one of the rare dragon weapons, is formed by a drake's tail. ''So it is considered a rare dragon weapon, even though it does not come from a true dragon. The description goes on to explain: Drakes are seen as undeveloped imitators of the dragons, but in they are likely their distant kin and this is reflected in the accuracy of the weapon's name "Drake Sword" rather than "Dragon King Magic Sword of Doom" or some such. So, it stands the reason the "Dragon King Greataxe" likely came from an actual Dragon King.

Observation based on evidence. :)
