The third and final episode of the Gems Trilogy.
It’s been three months since the events of The Sweetest Gem and The Gemmed Satyr, and frankly, everypony is emotionally on edge.
Can Fluttershy stomach up the courage to tell Rarity what she really wants out of their relationship more than anything else? When Rainbow Dash finds out a dark secret about Applejack’s boyfriend Caramel, will she prevail when her conscience can't decide whether she should tell her friend?
Does Sweetie Belle really have good reason to worry about her future with Spike, and his faithfulness to her? And just why has Pinkie Pie been so keen to hang out with Twilight lately, and what's this she keeps spouting about the 'prophecies coming true'?
But these are only the roots of their problems. Trouble is brewing. Strange things are happening all over Equestria, one of the royal sisters has mysteriously disappeared, a familiar evil is about to rise again, and the fate of all the hearts in Equestria will lie in six ponies’ own troubled hearts as well as a mystical field talked about only in myth.
