Inequality exists everywhere in the universe. Even before a person is born, he will be confronted with these inequalities. Being born into a noble family is already an advantage given by parents. Being born with magical talents is an advantage given either by a lineage or by a heavenly blessing.
That is why people called geniuses would probably become garbage cans if they were born on a low-ranking planet or with an elemental bloodline; it is also reciprocal for a garbage can without talent or luck if it was born in a family or on a planet with advantageous conditions...will become a genius!
But this saying is all the more true when it comes to animals. Contrary to what most people think, hierarchy exists everywhere, even in the wild. A magical beast that belongs to the common species will have no chance to defeat a beast that belongs to the noble species.
And these noble beasts are also called the ancestral beasts of the supreme goddess!
