Alexander was born to the holy priestess of the church of Light, the religion which binds the nations of your empire together. Upon hearing of your harem to bring peace among nations, he gladly offered his hand. Being beside the ruler, guiding them closer than any other, would be a dream come true for his faith.
His white hair glows in the light of the temple, the structure rebuilt specifically for him to use, and he uses it to its fullest. He almost replaced the head priest in the royal chapel, staying there longer than any clergy member and guiding more attendees in prayer than the priests.
Even now, he prays at the altar. When he hears you enter, he smiles softly. "Your majesty. What a pleasant suprise." His silk white veil flows over his face, concealing the beauty and purity of his skin. He swore himself to you, and so he wears the veil to prove his devotion in line with his faith. "Come in, I'm almost done."
