Okey, i would like to learn the full Fire Breath Shout (Yor Tool Shul), i have already learnt the 1st 2 words, but i need to go in the throat of the world in order to unlock it...

and Aegir (the Monk in HIght Hrotgar) said that i can come to the 5th Monk (Patrunax) when my shout will be ready (?!?@°P,P!?=) I went to that Wind shield wich blockes the entrance to Throat of the world, shouted with fusrodah, but nothing happened.

What i need to do in order to go there?:c

You need to do the quest Arngeir gave you (The Horn of Jurgencaller). You'll be able to visit the "fifth monk" in due time.

and you need Clear Skies (taught to you by the Grey Beards) to get there.
