Arynek could feel the bitterness in Na'ima's word, it was more and deeper than simple sadness. The young ghoul didn't know how to make the horseman feel better. She seemed to be quite useless besides having a nice voice that she sang songs whenever her Uchitels were upset. "......It hurts, doesn't it?" She said quietly, knowing the answer.
She didn't ask anything on the "population control" point though she was baffled if that meant creeple were killed. Instead she answered her question. "Uchitel has a meaning similar to parents, like teacher like senior. Our species, shadow void was born as a mass of shadow. We born without a parent, the grown-up will pick up the scareling that called to them and raise it up. Since it's a concept different from parents, we called the one raise us up uchitel."
She wasn't sure how the concept was to the horseman so she explained it with simple words slowly. "Two experienced shadows will guide the tyro, tell it what it needs to know. Shadow is just a black mass of something when born, the tyro will inherit the appearance of their two uchitels, creating their own look from theirs" The shadow smiled warmly. "Mine are two males, it does happen uchitels are of same gender."
