(Ahem, clears throat) The Huns were the ones driving all those puny German and Teutonic (as the Goths were from modern Sweden) tribes before them in terror out of their homelands and into the territory of the decaying Roman Empire. The Huns, therefore, were the major cause of the fall of the Empire in the West. They also brought with them a military innovation in the laminated bow they fired from horseback, putting much more power behind the arrow. They were able to do so on the basis of another innovation - the stirrup - that they also introduced to the clueless and backwards Europeans, barbarian or civilized. Language? Just have them speak HUNgarian Yes the Magyars were a different people, but they came in on the same script - from central Asia, on horseback, invading terror, non- Indo-European language, yada, yada. And they likely bore some linguistic relation to their Hunnish predecessors. And Attila is a modern Hungarian name in use.
