This story is a sequel to Love's a Drag-on

It was a love story that seemed meant to never be. Two young dragons in love, torn apart by their differences. That was ten years ago. Now in their teens, the two dragons may yet again be entwined by the threads of fate. Only this time, under more dire circumstances, for dark forces linger in the depths of the Dragonlands, and they have their sights set on Equestria...

(Sequal to "Earning Freedom". Might be able to stand alone, but it's best if you read the first one before this)

After Big Macintosh escaped wrongful incarceration, thanks to foreign stallion named: Sin, He, Spike, Sin and another pony with questionable sanity named: Shade traveled around Equestria to live life without the constant frustrations and restraints of home. However, due to a double cross by Princess Luna, Sin found himself on trial for for assisting ponies he believed wrongly imprisoned, liberate themselves from such disgusting misuses of power and authority.

The four were joined by Twilight, Applejack, Rainbow Dash, and Pinkie Pie under order of Princess Celestia as Sin's sentence for his guilt. The eight ponies found themselves among the ranks of the "Bloody Sky Captains", the freedom loving crew of the airship "Gonshinian". After seeing life stripped for the first time by the hands of his mentor, Macintosh is in shock. He had never thought death acceptable by any circumstance, though; his life had never been directly threatened before either.

After a brief conflict with the Triple M. airship: "Judgment", The "Gonshinian" has been in travel for the past week due north over the Griffin Empire to transport Sin, a former Senator of the Federation, to his homeland to investigate a suspicious lobbyist campaign. Though the motives are not yet clear, the effects seem to drive a wedge between the representative Senators, and the arbitrating Centaurs. All compliments of a Mega Corporation named: Triple M. and it's well known Vice President: Malich.

(Spyro seriesXmlp) Spike's always been curious about his race, but then again what dragon wouldn't be when all they've ever known is ponies? So when a spell book arrives that may offer some answers to his questions, with a little help from Twilight of course, the young dragon is overjoyed to say the absolute least.

Though when things somehow end up going astronomically sideways, Ponyville finds itself playing host to three unexpected visitors; three scaly visitors by the names of Spyro, Cynder, and Ember to be exact, each bringing their own personal touch of chaos to the small town.

Soon awkward and unusual situations arise, tempers flare with destructive consequences, personal demons and ancient evils threaten to rear their long suppressed heads, and Spike learns that sometimes, if you wait long enough, love will find you.
