Rainbow Dash, Rarity and Fluttershy travel to the frozen north of Equestria and there, they encounter King Sombra. Armed with new abilities, they proceed to do battle with him. However, even with their new powers, they still have trouble with engaging him directly, with the kind of power he possesses. Rainbow Dash, being the Element of Loyalty, fights stronger than all the others and goes all out to protect her friends. However, even this is not enough to defeat King Sombra, and he eventually pins Rainbow Dash down and kills her. All seems lost, but then suddenly, Rainbow Dash stands up once more.
Note: This is actually a part of another fic that I was writing, but I have since scrapped it. This scene is what inspired me to write it in the first place. I like this part so much that I decided to make it a small, independent story. Enjoy.
