The word "treason" is the most feared word in all the ten cities of Maldonia. First, it symbolizes death. Either by being hanged or beheaded, ever since the existence of dragons in Maldonia. The word treason also meant you can be burned by dragon's flame until your bones turn black and your meat to ashes. This was a law passed by Artemis himself.
So what's the worst death if you were to choose? Was it being hanged by the neck till you die, or the quick death of being beheaded? Or would you rather die screaming by fire? Those options stood right in front of Matthew's eyes and he had no idea what to choose.
Two days passed ever since he was found guilty of treason against His Grace, the King. Lord Hofun returned back to Sea Tone and abandoned his son, he told his people that Matthew was lost and he can't be saved anymore. At least this time his first son Aegon agreed with him on that matter.
