Nothing lasts forever, not even a planet. In the distant future, Equestria no longer exists, the land stripped of all its life and resources. As a final resort, the princesses who guarded their world put into motion the only plan that could save their people. Colony ships, each one led by a princess and sent to a different candidate planet, ensuring redundancy.

It was the best plan they had. But any plan needs to have room for adaptation. The planet of Eldyrea was not forgiving to Equestrians. To survive, those who landed had to accept a new change: the chimaera. They walk Eldyrea on two hooves, in the scales of dragons. They wear the manes of kirins and look through the sharp eyes of griffons. And for as long as they could remember, they were alone in the world.

When two young chimaeras, Nisus and August, find themselves face to face with the creatures of their legends, the secrets of how they grew from a seed of metal and magic will force them to question their identities as Eldyreans. United with their kind to face their new rivals, they will understand why they have been left alone under the light of a wild star.
