When Twilight Sparkle mysteriously appears and tells Princess Luna she needs to be saved, Luna finds herself fighting an adversary that neither steel nor magic can dispose of.

Everything had went well, for better or worse. Ember and Thorax managed to get along, much to Spike's relief. They even seemed to almost touch base on a personal level, but it was then that Spike felt his gut knot up. He felt a hint of possessiveness, a slight sliver of anger... Even Spike knew it was jealousy, but what he couldn't figure out is why? They were being friendly... too friendly? Spike takes on an adventure of self-discovery, one that'll leave Spike forever changed... for better or worse.
