Twilight Sparkle had been spearheading a scientific research project, leading her to design and build a fleet of ships never seen or heard of in the annals of time. Blasted forth on a wave of incurbable curiosity.
Once the first set of ships had been built, there is a flash of recognition, and the Pink mare takes it all over on the mere hint of where she could take it. Instant knowledge of what she had before her, and what it was pushing forth.
Celestia, Luna, Cadanse and even Twilight is staring in pure amazement and horror, the speed the project had taken up, on the instant Pinkie Pie stepped up, and pushes the project on with relentless force and ingenious changes, to what had been little more than a small fleet of ships.
Once the new commanders had been named, the differences are pushed into clear view and the ships are pushed forwards on the wings of what could be.
