The series is based on a book called Wool by author Hugh Howey. Wool eventually spawned sequel novels, and all of that material was used in the creation of Apple TV’s Silo. streaming series. However, the series doesn’t exactly follow the books, and even if you read them all, you might not understand everything that happens in the series.
We are here to help you. Silo Season 2 ended on a big cliffhanger, with a lot to take in and understand.
The biggest question left by The silos the season received both a response and a lack of response. This question is: what is behind the giant door?
We will give you a more complete answer and explanation to the mystery of The silos giant door in this article. Don’t worry, we’ll also give you a big warning before we run into any major spoilers for The silos next season.
Spoiler-free section to start.
How Silo revealed the door

Lukas Kyle (Avi Nash), the ever-curious new IT shadow, discovers the giant door. He is led to the gate by following a series of codes and clues left by an infamous figure from the silo’s past, a man named Salvador Quinn.
The door is hidden deep beneath the silo, in an area where the abandoned digging equipment that excavated the silo has been left to rot in what appears to be an underground lake of water. No one in the Silo knows how to swim, so of the very few people who have managed to do so, almost none of them have bothered to explore the lake.
Lukas bets that the lake is not as deep as it seems and boldly jumps in, proving his hypothesis that it is only waist deep. He passes to the other side, where he discovers a large door, a giant door guarded by what looks like some sort of computerized guard.
What the door says Lukas Kyle

The voice speaks to Lukas and informs him that if he tells anyone what he learns there, a safeguard will be adopted. This save will kill everyone in its silo. We later learn that something deadly is poison.
Is there poisonous gas hidden behind the door? The door seems a bit big to be used solely as a poison gas dispenser, and there are no giant doors in Hugh Howey’s books. Silo the streaming series is based on.
For now, the exact nature of the door remains unknown. We know that the voice behind the door listens and watches everything. If Lukas reveals this secret to anyone, the poison he controls will be released and everyone inside his silo will die.

We learn that it might be possible to stop the gate guard from releasing his deadly poison, thanks to the work of Solo’s parents (Steve Zahn) in a nearby silo. But why would these silos have pipes full of poison, ready to be distributed? Why would anyone set up something like this? It is the thing Silo’s second season doesn’t answer, and that answer is more dire than you probably imagined.

From here on out, we’re going to dive into the spoilers for Silo season 3. Don’t go any further if you don’t want to know.
For what Backup exists and how to beat it

THE Silo The season 2 finale hints at where things are headed when it returns to the past and shows us a meeting between a young senator and a reporter.
These scenes from the past will become a dominant part of the show’s next season as we begin to uncover the truth about who built the silos and why. The secrets of the creation of the Silos have already been revealed in the books, and we will use these sources to give you clues about the secret background hidden inside the Silos. Apple TV to show.

From the books we know that there are 50 silos. Juliette’s (Rebecca Ferguson) original silo is silo 18. Solo’s silo is silo 17. They are all the same except silo 1. Silo 1 is the control silo and it uses cryogenics to sustain life and at work the founders of the Silo system. by teams to manage the 50.
The poisoned pipes, apparently behind the giant door discovered by Lukas, serve two purposes.
The first objective is to control possible rebellions. If a rebellion breaks out, the poison will be released to wipe out the population of the offending Silo.

You probably assumed that the people of Silo 17 died because they got out. If you think about it carefully, you will realize that this makes no sense. Opening the outer door would have only killed the first of them to come out, in which case the others would have seen these pioneers die and closed the door.
What really happened in Silo 17 was that the poison was released and the people of the Silo tried to escape. They found themselves trapped between the poison rising from the depths of the silo and the poisoned air outside the outer door. The result was the mass death we saw when Juliette crawled over the corpses of the population to enter Silo 17.
However, eliminating rebel silos is only a secondary objective of poison. The true purpose of poison, as outlined in Hugh Howey’s books, is to eliminate the unworthy.

The plan of the Silo system is to wait until it is safe to exit, then select the silo they deem most worthy of survival in the new world. That the inhabitants of Shiloh will be freed from their underground city to repopulate the surface of the Earth. Anyone left in all the other silos will be killed.
What is behind the big door of the Silo?
And the door? Even though we know the poison guard exists, we don’t know for sure if the door is nothing more than a giant lid for a poison dispenser. The poison could be coming from somewhere else and if so, what’s behind the giant door?

We’re only guessing, but the giant door could be access to another silo. Although there is no giant door in the The wool books, at one point, the inhabitants of Silo 18 dig a tunnel to connect their Silo to the neighboring one. It’s possible that the series plans to simply open this door rather than go to the trouble of digging a new tunnel.
Or maybe it’s actually a giant pipe filled with poison.
You’ll probably have to stick around for Silo season 3 to find out. While you wait, pick up a copy of Hugh Howey’s Wool books. They’re worth reading whether you’ve already seen the series or not.
