Spike led Thorax into the throne room of the Crystal Castle confident he could convince the others that the changeling could be trusted. That he meant no harm, and instead wanted to be an ally and live peacefully with them. That he could make them see Thorax for what he really was. That they could befriend the changeling and accept him as one of their own.

They didn't.

And consequences followed.

Also, apparently, an animated trailer.

In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

After the first night of celebration in Ponyville, Spike woke up to find himself as his pony caretaker, Twilight Sparkle. To add to his shock, the original Spike still acted like the dragon himself. Who was he then?

Facing with such a bizarre occurrence, the now-pony decided to go about fixing it alone, and trotted down a path of unknown.

In their quest to earn their Cutie Marks, and possibly find some answers for the strange events that have occurred, Sweetie Belle, Apple Bloom and Scootaloo soon learn they've taken on more than they can handle. How will they deal with this? And what will Sweetie Belle do now?

Sex tag is there for innuendos and references to the act in later chapters. There will be no clop.

This is a crossover with the show Danny Phantom, and a side story of Guilt of a Phantom. I would suggest reading that story first, as this story will interact with the main story from time to time. Especially in the beginning of this fic, as it will start after certain events at the hooves of our three fillies.

And click: The Baltimare Incident for the story that happened before Goap and SS, GoE.

Read them in this order.
1. Guilt of a Phantom.
2. The Baltimare Incident after the chapter: Hunting the Hunter's Hunter. Earth.
3. Silver Spirit, Ghost of Equestria after the chapter: The Day the World Looked Pink-ie Pie.
