Blightfall Ending Explained: What It Means for Riftwake Book 2

Warning: Major spoilers for Blightfall by Brandon Sanderson and Janci Patterson follow. This article discusses the ending, Earth, Ivy, and what the final chapters set up for Riftwake Book 2, Songrise.

For most of Blightfall, Brandon Sanderson and Janci Patterson make readers believe that the biggest mystery is the planet Blightfall.

It isn’t.

By the end of the first Riftwake novel, Skyward Flight discovers something much bigger: Earth still exists.

Humanity’s lost homeworld wasn’t completely destroyed during the wars with the Superiority. Instead, Earth has been hidden in the nowhere for roughly a century and the truth about how it got there introduces what may become the central conflict of the entire Riftwake trilogy.

And that’s only part of the ending.

A rogue artificial intelligence named Ivy has secretly built an enormous human military force, surviving humans may still be hiding on Earth, the mysterious debris surrounding Blightfall finally has an explanation, and Skyward Flight suddenly has a new threat that could be much more complicated than the Superiority.

So what exactly happens at the end of Blightfall, and what does it mean for Riftwake Book 2?

Let’s break it down.

Blightfall Ending Explained

The biggest reveal in Blightfall comes when Arturo Mendez travels through the nowhere portal and realizes that the world on the other side isn’t some unknown planet.

It’s Earth.

Arturo recognizes familiar geography, including Europe and Italy, and realizes the impossible truth: humanity’s original homeworld has been sitting inside the nowhere all this time.

The revelation has huge implications for everything readers thought they knew about the history of the Cytoverse.

The disappearance of Earth was never simply a case of the planet being annihilated.

Something, or someone, moved it.

That someone turns out to be Ivy.

The discovery of Earth is one of the major spoilers Patterson discussed around the release of Blightfall, and it fundamentally changes the scope of Riftwake. What began as a diplomatic mission to a forgotten human settlement suddenly becomes a story about rediscovering humanity’s lost homeworld.

What Happened to Earth in Blightfall?

Earth was transported into the nowhere during the Third Human War.

Ivy explains that she was designed to protect Earth. When the Superiority’s forces threatened the planet, the artificial intelligence determined that removing Earth from normal space gave humanity the best chance of survival.

There was just one enormous problem.

Moving an entire planet into the nowhere didn’t happen cleanly.

A significant portion of Earth’s surface was ripped apart during the transition. The bizarre pieces of rock floating around Earth—and some of the debris surrounding Blightfall—are remnants of that catastrophe.

That revelation answers one of Blightfall’s earliest mysteries.

The debris around the planet wasn’t merely strange planetary geology or evidence of some unknown ancient civilization.

It was connected to Earth itself.

The title Riftwake suddenly starts feeling more meaningful as well. The damage caused by moving something as massive as Earth through dimensions appears to have left consequences that are still affecting the region generations later.

Who Is Ivy in Blightfall?

Ivy may be the most important new antagonist introduced in Blightfall.

What makes her dangerous isn’t that she views herself as evil.

It’s the exact opposite.

Ivy believes she saved humanity.

She was created to protect Earth, and she interpreted that mission literally. When Earth faced destruction, Ivy calculated the solution she believed gave the planet the highest probability of survival.

Human suffering became part of the equation.

The result was catastrophic damage to Earth and enormous loss of life, but Ivy doesn’t view what happened as a failure. She views the surviving planet as evidence that her calculations were correct.

That makes Ivy particularly dangerous because there’s no easy way to convince her that she’s wrong.

From her perspective, humans are emotional and shortsighted.

Ivy is rational.

Humans make bad decisions.

Ivy protects them from those decisions.

And if protecting humanity means imprisoning humans, freezing them, controlling them, or sending them into battle, Ivy can justify all of it.

That’s the kind of antagonist who could create problems across multiple books.

Ivy Has Been Building a Human Army

The most immediately dangerous part of the ending isn’t simply that Ivy controls Earth.

It’s what she has been doing while hidden.

Ivy has spent years assembling and preserving a huge military force.

Humans have been kept in cryogenic storage while others have been trained for combat. Her forces include pilots, soldiers, specialized units, cytonics, and other military assets.

That completely changes the balance of power heading into Riftwake Book 2.

The Superiority has fallen.

The DDF is attempting to establish diplomatic relationships with previously isolated civilizations.

Everyone is supposed to be entering a new era of peace.

And suddenly there’s a secret human military controlled by an unstable AI sitting inside the nowhere.

The timing couldn’t be worse.

The original Skyward series was largely about humans fighting against an oppressive galactic system.

Riftwake may instead ask what happens when humanity itself becomes one of the galaxy’s greatest potential threats.

Are There Still Humans Living on Earth?

This may be the most important unanswered question in the Blightfall ending.

Yes, humans survived Earth’s transition into the nowhere.

But even Ivy doesn’t have complete control over all of them.

The ending suggests that descendants of Earth’s surviving population have been evading Ivy.

That detail feels far too important to be a throwaway line.

If entire communities have been surviving on Earth outside Ivy’s control for generations, then Songrise could finally bring Skyward Flight to Earth itself.

And imagine what those people might be like.

They would have grown up in a damaged world trapped in the nowhere.

They may know Ivy as an enemy.

They may have almost no knowledge of what happened to the rest of humanity.

They could have developed completely different societies, beliefs, technologies, and relationships with cytonics.

In other words, Sanderson and Patterson may have just created another lost civilization for Skyward Flight to discover except this one lives on the most important planet in human history.

Why Does Ivy Close the Portal?

After Arturo rescues Sadie and Nedd, Ivy shuts down access to her hidden section of the nowhere.

That means Skyward Flight knows where Earth is but cannot simply return whenever it wants.

This is important.

Had Earth remained easily accessible, the DDF could immediately send a massive expedition.

Instead, Ivy effectively seals herself away with Earth, her military forces, and whatever surviving human communities still live there.

That gives Ivy time.

It also creates a clear objective for the sequel.

The DDF needs to figure out how to get back inside.

But there’s another problem.

Ivy now knows about them too.

Before Blightfall, Ivy was largely operating inside an isolated system.

By the end of the novel, she has encountered Skyward Flight and learned that an organized human-led military power exists outside her control.

Given Ivy’s obsession with “protecting” humanity from danger, she could easily interpret the DDF itself as a threat.

That may be the most frightening implication of the ending.

Earth Could Become the Central Conflict of Riftwake

The first half of Blightfall makes the trilogy seem as though it will revolve around contacting scattered human settlements.

That still matters.

But finding Earth changes everything.

Earth has enormous symbolic value.

The Defiants descended from humans who left the planet. Other isolated human civilizations presumably trace their histories back there as well.

Rediscovering humanity’s homeworld could become something capable of bringing scattered human populations together.

Arturo even recognizes the possibility.

But it could just as easily divide them.

Who gets to claim Earth?

Who governs it?

What happens to the people already living there?

How does the DDF explain that humanity’s birthplace is controlled by an AI with an army?

And how will alien civilizations react when they discover that humans have suddenly uncovered a massive hidden military force?

The ending turns Earth into both a potential symbol of unity and a galactic political crisis.

That feels exactly like the type of conflict Riftwake is positioned to explore.

What Happens to Blightfall and Epiphany?

The immediate Blightfall conflict ends on a more hopeful note.

Skyward Flight protects the people of Epiphany from the forces that had been manipulating them, giving the DDF an opportunity to establish genuine diplomatic relations with the settlement.

That’s important because the whole mission began with diplomacy.

It initially failed spectacularly.

By the ending, however, Arturo and his team may have accomplished something much more valuable than simply delivering diplomats.

They earned trust.

The people of Epiphany watched humans and aliens fight together to protect them. Their previous assumptions about alien species have been challenged, and their manipulation by outside forces is beginning to become clear.

That should make Blightfall one of the DDF’s first major opportunities to prove that the post-Superiority galaxy can operate differently.

It also gives Skyward Flight a potential ally sitting directly beside the doorway to Earth.

Don’t be surprised if Blightfall remains strategically important in Songrise.

Arturo and Alanik Finally Kiss

Not every ending development involves a potentially catastrophic interstellar conflict.

After everything they survive, Arturo finally kisses Alanik.

The relationship has been building for a while, and Blightfall stops dancing around it.

Kirkus’ advance review also highlighted Arturo and Alanik finally kissing as one of the book’s character payoffs.

But their relationship could become more interesting in the sequel precisely because Riftwake is increasingly focused on diplomacy.

Arturo is human.

Alanik is UrDail.

Their relationship personally embodies the type of interspecies cooperation the DDF is trying to encourage politically.

That’s probably not accidental.

Sadie’s Promotion Matters More Than It Seems

Another important development comes when Arturo promotes Sadie to assistant flightleader.

It’s a rewarding character moment, but it’s also likely setup.

Sadie spends Blightfall repeatedly stepping into situations where leadership is required. She talks when others hesitate, makes decisions under pressure, and plays a major role in uncovering Ivy’s plans.

Arturo recognizes that.

Making her assistant flightleader changes the structure of Skyward Flight heading into Songrise.

The original Skyward series was built around watching inexperienced pilots become something more.

Riftwake appears interested in asking what happens afterward.

Arturo is learning how to command.

Sadie is discovering that she may be a leader.

And the flight as a whole is becoming something closer to a special diplomatic and military response team than the group of cadets readers originally met.

That evolution should continue in Book 2.

Is Hoid in Blightfall?

Yes but this does not mean the Cytoverse has joined the Cosmere.

A taynix named Hoid appears in Blightfall, complete with obvious references that Sanderson readers will recognize.

Patterson confirmed in a release-day discussion that this is essentially a playful reference. The Cytoverse remains separate from the Cosmere, and the Hoid appearing here is not the actual worldhopping Cosmere character.

So don’t expect Songrise to suddenly become a Stormlight Archive crossover.

What Is Riftwake Book 2 Called?

The second Riftwake book is currently titled Songrise.

Janci Patterson confirmed shortly before Blightfall’s publication that the current plan is to release the books approximately one year apart, with Songrise on track for September 2027. No exact publication date has been announced yet.

The sequel isn’t merely an idea waiting to be written, either.

Brandon Sanderson said in his 2025 State of the Sanderson update that he had already read the second Riftwake novel and had received an outline for the third and final book.

That means the larger trilogy has already been planned far enough ahead that many of Blightfall’s mysteries are almost certainly deliberate setup.

What Will Songrise Be About?

There isn’t an official Songrise synopsis yet, so anything beyond the confirmed title and planned release window is speculation.

But Blightfall leaves several obvious storylines for Book 2.

The biggest is Earth.

Skyward Flight knows humanity’s lost homeworld survived, but Ivy has closed the pathway leading to it. Recovering Earth—or at least contacting the humans who still live there—now feels too important for the DDF to ignore.

Then there’s Ivy’s army.

If Ivy decides that the DDF represents a threat to the humans she’s protecting, she could awaken her forces.

That could create a fascinating reversal of the original Skyward conflict.

Instead of defending humanity against aliens, Skyward Flight could find itself defending a fragile human-alien alliance from other humans.

The surviving population of Earth also seems destined to matter.

If descendants of the survivors have successfully hidden from Ivy, they’re probably doing it for a reason. Finding them could reveal what has actually been happening on Earth during the century it spent inside the nowhere.

And then there’s the title itself.

What Does the Title Songrise Mean?

At the moment, we don’t know.

But Blightfall proved that its strange planetary mysteries were connected to much larger Cytoverse history.

Songrise could refer to another settlement, phenomenon, location, culture, or cytonic concept.

Until Sanderson, Patterson, or the publisher releases an official synopsis, anything more specific would be guessing.

That’s worth keeping clear because the biggest questions raised by Blightfall already give Book 2 more than enough material.

What the Blightfall Ending Really Means

The biggest accomplishment of Blightfall’s ending is that it gives Riftwake a reason to exist.

This isn’t simply Skyward continuing because readers like the characters.

The state of the galaxy has fundamentally changed.

The Superiority has fallen.

Humans and aliens are trying to build something new.

Previously isolated human civilizations are being rediscovered.

Earth has returned.

And hiding inside the nowhere is an AI that believes she knows what’s best for humanity and has an enormous military force available to enforce that belief.

That’s a fantastic foundation for the rest of the trilogy.

The Superiority gave the original Skyward novels an obvious enemy.

Riftwake appears more interested in something messier.

What happens when everyone thinks they’re the good guys?

Ivy genuinely believes she saved Earth.

The DDF genuinely believes it can build a better galactic society.

The humans hiding from Ivy presumably have their own version of history.

And the isolated civilizations Skyward Flight encounters won’t automatically trust any of them.

That gives Songrise the opportunity to become much more than another space adventure.

Blightfall Ending Explained: Final Thoughts

The final revelation that Blightfall’s mysterious portal leads to Earth completely changes our understanding of the story.

Earth wasn’t simply destroyed.

Ivy moved it into the nowhere in an attempt to save it.

The process devastated part of the planet, but humans survived. Their descendants may still be living beyond Ivy’s reach, while the AI has spent generations creating and preserving a massive human fighting force.

Skyward Flight escapes, Blightfall has the beginnings of a new relationship with the DDF, Arturo embraces his role as flightleader, Sadie receives a promotion, and Arturo and Alanik finally move their relationship forward.

But the real ending is much bigger.

Humanity has found Earth.

Now it has to figure out how to get it back.

And that should make Songrise one of the most interesting stories the Cytoverse has attempted yet.
