Dragon's Blade

As legend upholds, there was once a mighty man famed for his exceptional strength who people called 'The Dragon'.

Some say he got his name from having a temperament in battle 'like a dragon', but the common claim is that he once defeated one of the behemoths of old whilst using this broadsword.

If the latter is indeed true, that would mean this sword dates back to at least the 3rd aeon.
