Game of Thrones season 8, Imminent Death.

Let me take this time to applaud the creative writers of this interesting HBO Tv series.
For many years now, Game of Thrones has been running year after year with interesting
new story lines and a lot of suspense. We've seen death, passion, betray to deceit. This
show has it all, and on it's 8th season, promises to be more epic.

Back to the reason for this post, in a recent poster, the one right below,

 we see the
White Walker King (Night King) standing on a heap of skulls. And on this heap of skulls,
two things caught my attention.

1. A sword (probably a King's sword)
2. A skull with a Crown.

Now. My questions are; Who could the crown and sword belong to ?
I have many theories but one that seems solid enough is who the crown belongs to.

In season 7 we see John snow become King of the North. And as such his beliefs in
the existence of the white walkers come to light as he faces a few of them.
In his quest to vanquish them, he seeks an ally in Queen Cersei Lannister.
He tells her if they do not face this treat together, their entire existence would
come to an end. Yet She refuses to help.

So this is where my theory comes in. If you take a look at the picture below,

C

you'll
see a crown on Cersei's head. Compare that crown with the first picture above. There's
a striking resemblance.

So could we possibly see the end of Queen Lanister? or could the Sword (just saying)
probably be for the King of The North ; John Snow? or Could Game of Thrones just end
with everyone dying or everyone becoming undead?

Tell me what you think , Do you have any more theories? Leave your comments right below
