2000 years ago, Equestria was met with Nightmare, the living incarnation of the cursed sword, Soul Edge.
By that, you mean 'a guy went to a convention in an awesome costume and ended up getting bit in the tail for it'.
He was defeated, and sealed in stone for all of eternity.

But now, he is free.
Whoo-hoo!
But much to his surprise, he is not alone.
Wait, what?
For now he is greeted with five faces that are… quite curious, to say the least.
To say the least. I wasn't expecting a quintet of fools to follow me to Candy Land.
But we're your friends, Nighty!
AND STOP CALLING ME THAT!
