The Dark Dragon was a deadly enemy of the Four Saints in the Holy War, with an especially deep enmity towards the Flame King Gilte, who had lost his nation because of it. Although Brand was puzzled as to why the witch Barbara would say such things, he couldn't agree this time. Otherwise, he might find himself opposed to the entire Bright World: "The Dark Dragon Odin? I know you witches regard him as the guide of dark destiny, but it has nothing to do with me."
He looked at Barbara and saw that this old witch was still respectfully kneeling on the ground, trembling like a leaf. Brand was slightly taken aback, realizing he'd gone too far. He forgot that the people of this world held great respect for deities and immense power, even if they stood in opposition, and would never speak disrespectfully.
As a player, he couldn't fully accept this idea; the other half of his reasoning came from Brand's influence. Thus, when mentioning these names, he naturally exhibited a sense of equality.
