Before Skyrim was released, I heard of a shout that would instantly teleport you behind your opponent. As far as I know, it's not in the game. Was this shout just a rumor, or was it removed from the game for some reason?

I'm putting this in the spoiler section because if I'm wrong and it is in the game, I'm sure people will get all bent out of shape for me revealing a shout.

Maybe it was the Whirlwind shout that you're taught after meeting the Grey Beards. It makes you're character move about 30 feet at lightening speed. This would be useful to move behind an enemy.

I never heard anything about a teleporting shout. Just whirlwind sprint as the guy above said.
