What is the Night King’s strategy? More aptly what is he looking for?

Potential Spoilers Below

I keep telling everyone that similarities between The Wheel of Time (TWOT) and A Song of Ice and Fire (ASOIAF) are vast even if there are those out there that say otherwise.

Per an interview Benioff tell us what the Night King is after: 

"I don’t think of him as evil, I think of him as Death,” Benioff told EW. “And that’s what he wants — for all of us. It’s why he was created and that’s what he’s after.”

OK so, he wants to rid the planet of sentient life.  So how does attacking Westeros do that?  Does he intend to systematically do it one village, town or city at a time?  I don’t think that is what he intends to do at all.  Within the series what is the most destructive force that we have seen?  Most people (i.e. TV viewers) would probably answer the Night King and his Army of the Dead.  Let me ask the question in another way.  What is the most destructive force on their planet at the current level of development of the inhabitants that we have seen to date?  I would answer that as the weather or nature itself.  Now let’s look at it from the point of view of this story. 

First, we learn of the story of the Breaking of the Arm of Dorne.   Stories tell us that the greenseers of the Children of the Forest used the hammer of the waters to make the seas rise and sweep away the land, shattering the land bridge that linked southeastern Westeros and southwestern Essos.  They did this in an unsuccessful attempt to end the invasion of the First Men.  The following are excerpts from the books that mention this story:

“The histories say the crannogmen grew close to the children of the forest in the days when the greenseers tried to bring the hammer of the waters down upon the Neck. It may be that they have secret knowledge.”

“where legend said the children of the forest had once called down the hammer of the waters to break the lands of Westeros in two.”

The second story is the Doom of Valyria which I see as more destructive.  An event not thoroughly explained that caused the downfall of the Valyrian Freehold.  An empire that stood for five thousand years was wiped out almost instantly.

It was written that on the day of Doom every hill for five hundred miles had split asunder to fill the air with ash and smoke and fire, blazes so hot and hungry that even the dragons in the sky were engulfed and consumed. Great rents had opened in the earth, swallowing palaces, temples, entire towns. Lakes boiled or turned to acid, mountains burst, fiery fountains spewed molten rock a thousand feet into the air, red clouds rained down dragonglass and the black blood of demons, and to the north the ground splintered and collapsed and fell in on itself and an angry sea came rushing in. The proudest city in all the world was gone in an instant, its fabled empire vanished in a day, the Lands of the Long Summer scorched and drowned and blighted.

An empire built on blood and fire. The Valyrians reaped the seed they had sown.

I think both events were caused by the same thing.  It was said concerning the shattering of the Arm of Dorne they may have had a secret knowledge.  I think the same knowledge caused the Doom.  More specifically I think the same device cause both.  And that is what the Night King is searching for as he doesn’t know the exact location of the device.  For those of you have kept up with my theories you know I believe that the device is located at the Isle of Faces.  I think that the device is similar to a device found within the Wheel of Time called the “Bowl of the Winds”.  During the Age of Legends, Aes Sedai using several bowl-shaped ter’angreal’s allowed its users to control the weather on a planetary scale.  I wrote about this theorized device a few years back; click here to read it.  I believe that a similar type device is what the Night King is after and if he gets his hands on it, he will be able to trigger a planet shattering event that could end all life on their planet. 

It is for this reason I think the attack on Winterfell is simply nothing more than a diversion.  If he wanted to just kill everyone, he could have done it before Jon and Dany could assemble their troops at Winterfell; taking out their base of operation.  Wights don’t tire why not just have them run day and night and get there before they arrive and again take their base of operation.  He himself could have destroyed Winterfell from the air on Viserion; the same as Aegon the Conqueror did riding Balerion the Black Dred assaulting the castle Harrenhal which was thought to be impregnable.  I believe he is drawing everyone who has knowledge to defeat his armies so that he himself can find what he is looking for and destroy the world unmolested. 

When I first saw the Lands of Always Winter on the TV show and saw the crystal spires jutting up from the ground  with the crystal pedestal at its center I immediately thought of the Bowl of the Winds.

Could this be a focal point for the theorized device that I believe exists within this world?  Could there be several other focal points around the globe?

Comments encouraged.  Love to hear the idea’s of others.  Most believe that since I present my idea’s as “fact like” I’m not open to change my viewpoints which is far from the truth.  I simply look at the information presented and go from there.  If you can shine a light on another way of thinking that opens the door to debate.
