Beyond the stars, two gods vie for rule of the world.

One stands for Nature – the belief that everything is stamped in flesh from the start. The other, Nurture – the belief that all is potential, that the true self is coaxed out through love and living.

And so, they take a bet.

Each immortal selects a set of twins as their champions. The twins that prevail in contest will decide which immortal rules….

In a westerly valley, a girl and boy are born to a noble family, to be raised by a mysterious teacher – ready to love and instruct them in everything, regardless of society’s expectations…

To the east, a woman washes ashore on an island inhabited only by a sorcerer. With her final breaths, she gives birth to twins. These two are raised with careful neglect by the sorcerer – surrounded not with love but with danger, magic and wildness.

Society expects these children to become men and women. But the immortals care nothing for human norms and raise the twins according to their own ends. Which twins will prevail?

What truly matters in determining who a person will become?
