Equestria's Contractor Storyline

I've finally decided to pin Hei and Yin up agains Chrysalis and her Changelings as the main villans of this storyline. I plan on creating some orginal characters that will be a more than a match for Hei. Now as for the other characters, I'm making Hei have a major connection with Luna and Celestia through this series, since both of them have the ability to look into Hei's mind, and under stand exactly how he feels. Yin plays an important part as you would expect, as a love interest for Hei, but that will come in later chapters. As for Chapter 3 I'm already Half way done with it, so it should be to long till I post it. If there any feed back on the story so far you wanna give just let me know.
