They both are in for the case of their lives, when the mayor of Ponyville calls them in because a criminal known as the "Cutie Mark Killer" is striking down on innocent ponies. Every Monday morning, a picture of a cutie mark is hung on the town hall door, and by Sunday evening the bearer is dead.

Twilight loves to discover, learn, and be amazed. So when rumours spread of ancient ruins existing in Equestria, and when a letter from the Princess of the Sun herself arrives with orders to check them out, she packed her saddlebags, said goodbye to her friends, and left.

And what she discovers inside will both amaze her... and frighten her.

A/N: Cover image was taken from the Fire Emblem wikia, and I realize it is Renault. I thought it fit the story's character.

The equestrians have forgotten us, forgotten of those they once fought side by side with, lived and coexisted with. Those who they had once called brothers and sisters. I am here to remedy that, to bring back the forgotten histories of Equestria.

Youtube reads by Spore Harvest start here.

He decides, with his breakthrough in spatial rendering, to leave the destroyed Earth behind and go for a new world. He aims to go to a fresh Earth, where everything is as it should be, without his existence.

Unfortunately, he goes slightly off-course, and ends up in the wrong world. How will his technology get him through this?

If any of you don't like a little pseudo steam-punk, then you shouldn't read this, because the main character's technology is heavily influenced on its style...except for three certain things.

The beginning of the story was inspired by "Techno-Babble in Equestria" made by N64Fan. You should go check it out. It's pretty good.

That work of art is "Steampunk Wanderer" by amlaidgh. I only found the name of the artist, so I don't know where it could have been originally posted. The original version of this art seems to be "Wanderer above the sea fog" by Caspar David Friedrich.
