Well everypony, time for the Crystal Gems and Mane Six's reprise. The Cluster, Malachite, the trio of problematic serpents, my goodness did they had plenty to deal with but with all that passed, and Lapis and Jasper returning once more, it's time for them to kick back and relax. ...

Yeah, as if.
Months had passed since these events, and winter's nearing its latest years before spring. With so many problems handled the year prior, you'd think they would be given a break but boy you were wrong. One visit to their Homeworld revealed another group of Gems known as the Off-Colors, a group of strange, yet intriguing Gems made up of defects, fusions, and some interesting information on the Crystal Gem war. ...

Now they got two new tasks: finding a home for Off-colors, and to find the real answer to a century's old mystery. Relationships will be tested, rivals will return, all with a looming diamond shatterer elusive to their midst. Onward everypony!
