Everything was looking up for them. As a loving couple should, they reunited once more under the bonds of harmony and settled their differences. They succeeded so much in such a short amount of time and even though the odds were stacked against them they were pulling through.

Then... there was a scream.

And everything fell apart.

Join Spike and Sweetie Belle as they reclaim the safety that was lost to them and march upon a fight they were never prepared for. But they will not be alone, for their friends stand with them to face the darkness that erupts the seeds of corruption and chaos.

What they do next will be told for generations to come.
