Many ponies have sworn by Celestia's beard over the ages, but where did this phrase originate from? Twilight Sparkle, her brain ever-thirsty for knowledge, asks this of her mentor, and learns a lesson she'll never forget.

Princess Celestia has just banished her beloved sister Luna to the moon for all eternity... but eternity is a very long time, even for an immortal. Can a strange colt with a blue box help make the time pass more quickly?

Some OCs for flavor, but focuses mainly on the Princess, the Nightmare, and the good Doctor.
