Fate and prophesy can be funny things. Sometimes harmony and magic can be a bit unpredictable.
Starswirl's last prophecy was unclear as the greatest spell caster of his day had notoriously bad horn-writing and was equally bad at only writing down half of what he saw in visions.
For generations Princess Celestia has been subtly manipulating the lives of her ponies for generations, using a combination of Starswirl's prophesies and her own foresight to get the outcome she wanted. But she forgot the three most important rules about trying to manipulate future events: 1) The future is like a river. It follows its own currents and makes its own path. 2) The future is always in motion and is next to impossible to predict with any certainty. 3) The very act of viewing the future changes it.
This story is an AU from the main MLP:FiM starting with a deviation from the episode Magical Mystery Cure.
It all started with a single question: What if it was the Mane 6 that became alicorns and not just Twilight?
It's rated T for mild violence.
