The Great Pendragon
The infamous horse Archers of Attilla, the Scourge of God. They forced the Eastern Roman Empire to sign the treaty of Margus, gaining annual tribute from them; and then attacked the Empire anyway!
Their spread across the world seemed unstoppable until the death of Attilla. His son Ellac lacked the ability to maintain the fledgling confederation of tribes, and they are now a shrinking empire.
When their thick bladed short swords and daggers, and the gilded bows of their elite warriors are coordinated; they are still a force to be reckoned with when encountered. But infighting between the clans of the Hun confederation almost guarantees their eventual demise.
the only known Huns in Logres at this time (as of 498 AD) are the personal guard of Preator Syagrius
