Bahamut's summoning is essentially to transform oneself into a descendant of Bahamut's Dragon.
zhao xu explained when he saw the confused looks on everyone's faces.
from humans to elves to other humanoid races, they all have the possibility of becoming Dragons. In essence, this is a kind of rebirth, not pure breeding.
generally speaking, most of the people who can become Dragon descendants hear the Platinum Dragon's Call during their adolescence. Some of them only discover it after they become adults or even after their careers. However, not everyone responded to the call.
As he spoke, Zhao Xu silently stretched out his wand. In an instant, the bonfire in front of him transformed into the Holy emblem of a shield with a dragon's head. It was the Holy emblem of the God of the good Dragons, Bahamut.
