Before deciding to meet Bronia, Muria had some speculations about the identity of this Ancient Red Dragon, or rather, he had some guesses about the relationship between this Five Colored Dragon and his own mother.
The Golden Dragon Mother had let the Five Colored Dragons she had raised disperse among the twelve subcontinents, and Muria could be certain of one thing. The place where they initially landed was absolutely safe, and there were no existences nearby that could threaten their lives.
The Golden Dragon Mother could never have expelled them to human capitals or dark elf main cities. This wouldn't count as expulsion, it would be execution. If they really went there, their Gold rank strength would be far from adequate, they would be easily captured, flayed alive, their heads would be cut off, and hung on the wall to dry.
Transporting Muria's dragons to such a place just wouldn't make any sense, it would be better to just slaughter them right away.
