YEs thats it, some how some way if they represented it in this game would be neat i mean you never know.

Another possibility is that the Greybeards and Thu'um will feature in the game (which is actually very likely, if you ask me) but not as a skill that can be learned by the player.

"The Tongues"

The Nords have long practiced a spiritual form of magic known as "The Way of the Voice", based largely on their veneration of the Wind as the personification of Kynareth. Nords consider themselves to be the children of the sky, and the breath and the voice of a Nord is his vital essence. Through the use of the Voice, the vital power of a Nord can be articulated into a thu'um, or shout. Shouts can be used to sharpen blades or to strike enemies at a distance. Masters of the Voice are known as Tongues, and their power is legendary. They can call to specific people over hundreds of miles, and can move by casting a shout, appearing where it lands. The most powerful Tongues cannot speak without causing destruction. They must go gagged, and communicate through a sign language and through scribing runes.

In the days of the Conquest of Morrowind and the founding of the First Empire, the great Nord war chiefs - Derek the Tall, Jorg Helmbolg, Hoag Merkiller - were all Tongues. When they attacked a city, they needed no siege engines; the Tongues would form up in a wedge in front of the gatehouse, and draw in breath. When the leader let it out in a thu'um, the doors were blown in, and the axemen rushed into the city. Such were the men that forged the First Empire. But, alas for the Nords, one of the mightiest of all the Tongues, Jurgen Windcaller (or The Calm, as he is better known today), became converted to a pacifist creed that denounced use of the Voice for martial exploits. His philosophy prevailed, largely due to his unshakable mastery of the Voice -- his victory was sealed in a legendary confrontation, where The Calm is said to have "swallowed the Shouts" of seventeen Tongues of the militant school for three days until his opponents all lay exhausted (and then became his disciples). Today, the most ancient and powerful of the Tongues live secluded on the highest peaks in contemplation, and have spoken once only in living memory, to announce the destiny of the young Tiber Septim (as recounted in Cyrodiil). In gratitude, the Emperor has recently endowed a new Imperial College of the Voice in Markarth, dedicated to returning the Way of the Voice to the ancient and honorable art of war. So it may be that the mighty deeds of the Nord heroes of old will soon be equaled or surpassed on the battlefields of the present day.

They need some good Scandinavian voice actors for this. Like. Mads Mikkelson, and the dude who played Buliwyf from the 13th Warrior.

I forgot what it was called but basically some specially trained Nords could use their voice like magic and REALLY do some damage, this is all from memory from something I read. I just barely remember this maybe some one can elaborate and it if it is really part of the lore I hope to see something new in the game.

Essentially, no Greybeards aren't the only one who can do it. It's basically the equivilent to Ra'gada sword play, though, very interesting, but near impossible to show in any meaningful way mechanically.

It's really just a variation on the normal magic system tweaked for if you want to PLAY BRIAN BLESSED!!!!!!!!!!!!!!!!!^!!!!!!!!!!
