@SunSun Daxia in that context means great hero or warrior but the DaXia here are 2 different words which are used as the name of a nation/alliance. The Da here is the same meaning large or great while the Xia is the historical term for Chinese culture.
@solmeggido : this doesn't change anything, all the former heads of the dragon slayer alliance should be used to add red paint on the evil dragon's ship. \o/
