"Game of Thrones" Season 8 is still over a year away, and "The Winds of Winter," the sixth installment of George R. R. Martin's "A Song of Ice and Fire" book series, is nowhere near its release. But the absence of everyone's favorite fantasy series doesn't stop the fans from speculating about what's going to happen next in both the books and the TV show. So in the process of figuring that out, the fans often come up with all sorts of strange connections and theories, even though most of these theories won't come true, especially in the TV show with only six episodes left.

But they do provide some excellent food for thought during the offseason. With this in mind, let's talk about the mysterious weirwood trees.

Everything you need to know about the weirwood trees

The weirwood trees are beautiful, but terrifying at the same time. Their barks are pale white, their five-points leaves are the color of blood, and most of them have faces carved into their trunks. It was the ancient race of the Children of the Forest who carved these faces to help the greenseers with their powers for it is through the eyes of the weirwood that they were able to see the past, present, and the future.

The Children of the Forest worshiped the weirwood trees as gods. So did the First Man after the Pact.

And their descendants in the North still do. But before the Pact there was a war between the two races. From the moment the First Men came to Westeros from Essos, they started cutting down these sacred trees. So to fight back, The Children shattered the land bridge that connected the two continents called the Arm of Dorne with the help of powerful magic.

But that didn't help as they were already seriously outnumbered. Then, the Children tried to perform the same magic on the Neck, but they only flooded the area.

But however magical these beings seem to be, the question remains as to how exactly were they able to perform this kind of magic. And that brings us to today's theory.

The weirwood connection

The Children of the Forest, otherwise known as Those Who Sing the Song of Earth, believe that when they die their spirits go into the trees, their memories are therefore preserved, and that's how they become one with the gods. But that's not all. For these gods need the constant blood sacrifice. It was because of this sacrifice that Children were able to shatter the Arm of Dorne. But when they decided to do the same with the Neck they couldn't because there was simply not enough blood.

According to YouTube user Ideas of Ice and Fire, the sacrifice to the weirwood trees was the part of the Pact. And since this kind of sacrifice is no longer common amongst men, then they are in serious violation of this Pact.

So perhaps the Children created the White Walkers for the sole purpose of feeding the trees with the hot First Men blood so they could have the North only for themselves. But somewhere in between the plan went terribly wrong and the White Walkers turned against their creators, and now they are coming again; 8,000 years after the first Long Night, to seek revenge against the humans and the Children of the Forest alike.
