Why there are no Blonde Sarans

Quote and Question:

"The recent events you all witnessed and

experienced were caused by an old prophecy and the uncanny and unmatched beauty of you, Melissa. You see our highest goddess is depict and described to look very much like you. Yet we Sarans have no genes that make us blonde naturally and has been against the law for over 2000 years to seek artificial, medical or genetic ways to alter this fact. Your sudden appearance and a certain passage in our book of gods made you into an instant pawn of several religious factions."

reason:  Sarans have no genes that make us blonde naturally
