Sarah J. Maas' best-selling Throne of Glass series. However, Maas has made several comments indicating that while the main narrative has concluded, "there are other stories in that world that [she] wants to tell at some point."

Considering next Court of Thorns and Roses novel, her comments about the next book in the lineup — stating "it’s a story that’s been brewing in the back of [her] mind for a long time" — are even more promising to a Throne of Glass continuation. Kingdom of Ash's ending also leaves a lot of questions unanswered, giving Maas many avenues to re-enter the narrative.

10 Manon's Reign As Queen Of The Crochan Witches

She Returns To The Western Wastes At The End Of Kingdom Of Ash

By the end of Kingdom of Ash, Manon becomes Queen of Witches over both the Crochan and the Ironteeth clans. Once the war with Erawan and Maeve is over, she returns to the Western Wastes with her people to begin her reign. Manon is one of Maas' most complex characters, transforming from a cold and ruthless follower into a strong, powerful, and empathetic queen by the end of the series. However, as Manon's acceptance of her new role comes towards the end of the final book, readers never get to see her truly begin her reign.

The uniting of the Crochan and Ironteeth clans is a huge deal, especially after the two witch factions had been warring for centuries. Manon was the one witch who could become queen and reverse the curse that was placed on the Witch Kingdom by the last Crochan Queen, and returning to the Western Wastes marks the start of a new era for the witches. If Maas does return to the Throne of Glass world at some point, it would be great to see how Manon's Throne of Glass character has further evolved as queen.

9 Seeing Yrene & Chaol As Parents

Yrene Is Pregnant At The End Of The Series

Kingdom of Ash kicks off with the revelation that Yrene is pregnant, and during the final novel, their future as parents becomes a heavy burden as they worry over the battle with Maeve and Erawan. However, the two are almost more encouraged to fight in the hopes of creating a better world for their child, and they both end up being essential in defeating Erawan—especially Yrene's healing ability. Unfortunately, the events of the final novel come to a conclusion before she gives birth, and readers never get to see the two characters become parents.

Since most of the narrative is focused on the pending war with Erawan and Maeve, there's little time for readers to get excited over the idea of their future child. Not only that, but readers are never made aware of the sex of the child or what they choose to name their son or daughter. While this detail is small and relatively unimportant to the plot, it's still something readers have long questioned and would love to know in a future Throne of Glass novel.

8 Nox and Aelin's Reunion

This Scene Is Notably Absent In Kingdom Of Ash

Aelin's attempts to reclaim her throne help her to reunite with several characters in the latter series, but one that was highly anticipated throughout Kingdom of Ash was with Nox—the young thief who competed with Aelin in the King's Champion Tournament in the very first book—is notably missing. Nox returns to the story mid-way through Kingdom of Ash, and is first seen as a messenger in Terrasen's army. However, it's during this scene that Nox realizes that Aelin Galathynius, who was actually Lysandra impersonating Aelin, was his old friend Celaena Sardothien in Throne of Glass.

During this scene, he comes to understand that Lysandra is not the real Aelin, explaining that she would have recognized him from the king's competition. After that, I was anticipating a heartfelt reunion between Nox and the real Aelin, but unfortunately, that never came to . There's a lot that happens at the end of the novel, but it seems like Maas genuinely forgot to add this scene, and if she continues Throne of Glass in some way later on, she should supply readers with the reunion that is missing from Kingdom of Ash.

7 Elide and Lysandra's Wedding

Kingdom Of Ash Features Aelin's & Rowan's But Not The Others

Kingdom of Ash wraps up everyone's romantic relationships nicely, with most characters finding their happy ending and securing a bright future. And while the end of the novel features both Aelin and Rowan's wedding, Maas doesn't have the time to also include Elide and Lysandra's. Instead, the two weddings are alluded to and Aelin mentions they are coming up in the next few weeks—with Elide and Lorcan marrying and moving back to Perranth, and Lysandra and Aedion marrying as well.

It's unfortunate there isn't enough time to see these events play out on-page as well, as most of us were equally invested in their romance arcs as they were with Aelin and Rowan's. It would be amazing to revisit these characters in a future Throne of Glass book and witness their weddings—especially when knowing Lorcan will be taking Elide's last name and henceforth be known as Lorcan Lochan, which is absolutely hilarious and would make for a great scene. The two heroines' love stories are equally important, and their weddings should definitely be featured in a future storyline.

6 A Maasverse Series Crossover

ACOTAR & Crescent City Have Already Done So

The third Crescent City novel, House of Flame and Shadow, was the first of Maas' fantasy book series to officially crossover into another book's world—bringing Bryce into ACOTAR's Prythian and seeing her interact with several characters. While this is Maas' first foray into bridging the Massverse together, it's definitely not her last. Given that the threat to Throne of Glass' world has been dealt with, it really only makes sense to revisit the narrative and create conflict if the Throne of Glass world collided with another of Maas' fantasy books—like Midguard or Prythian.

A book that simply detailed the lives of its characters after the war with Erawan and Maeve might be a bit too slow to be engaging, so Maas must bridge the gap between her fantasy book series and introduce a new threat that would create enough conflict to justify a ninth Throne of Glass novel. It would also be amazing to see how Aelin, even with her lessened magic state, would stand compared to other characters in ACOTAR or Crescent City, especially when considering she's one of the most powerful of Maas' book heroines.

5 A Monument Built For The Thirteen

This Is Promised At The End Of Kingdom Of Ash

The Thirteen's deaths in Kingdom of Ash are the most devastating moments in the entire novel. After telling Manon to "live", her most trusted friends and fiercest allies take to the skies to make the Yielding—a magical attack that when used will destroy their enemies but also take the life of the witch who performs it. In chapter 89 of Kingdom of Ash, Manon is left to watch as every single member of The Thirteen sacrifices their life to destroy the witch tower that threatens to destroy Terrasen.

"There will be a monument," she said to Abraxos, to Manon. "Should you wish it, I will build a monument right there. So no one shall ever forget what was given. Who we have to thank."

—Aelin Galathynius, Kingdom of Ash

Later, after the battle is won, Aelin seeks out Manon to offer whatever comfort she can provide. It's during this short scene that Aelin promises to build a monument to honor The Thirteen, and never forget their sacrifice and all those they saved with their heroic final act. Maas broke many readers' hearts with The Thirteen's deaths, and it would be comforting to know that Aelin did as she promised and built them a monument in a future Throne of Glass novel—and help provide readers with a sense of closure.

4 Dorian & Manon's Relationship

Their Romantic Arc Was Only Just Beginning

If Maas was going to re-enter the world of Throne of Glass, it makes the most sense to do so with Dorian and Manon, whose romantic arc was only just beginning to take shape at the end of the series. They have some flirtations in the early novels, but their relationship grows deeper throughout Kingdom of Ash. It's unfortunate the series ended before Maas could really define their relationship, and it's left open-ended on whether their romance will continue outside the scope of the narrative—especially now that the two characters are each rulers of their own kingdoms.

This element will make it even harder for them to have a relationship to the extent the readers are hoping for, as both will have responsibilities that keep them far from one another and far too busy to keep up a romance. There is also the issue of Manon being immortal and Dorian being human, ensuring that his lifespan will be much shorter than Manon's. However, despite these roadblocks, there is definitely a story left to tell—and hopefully, Maas will revisit their romance arc if she ever writes another Throne of Glass novel.

3 Discovering Where Vaughn Was Throughout The Entire Series

He Is The 5th Member Of Maeve's Original Cadre

Vaughn, a fae male who is a member of Maeve's cadre, is first introduced to the series in Heir of Fire and makes a brief appearance when he s Rowan and Aelin to fight the valg at Mistward. However, after this introduction, he never again re-enters the story and is only referenced in ing throughout the remainder of the series. At one point, it is mentioned that he's looking for Lorcan, but, surprisingly, he doesn't make an appearance at the final battle in Kingdom of Ash even though he's one of the only still loyal to Maeve.

This is one of the many questions we fans of Maas' Throne of Glass series have had about Kingdom of Ash's ending, and many assumed his character would make a grand appearance before the novel concluded. However, there have been several theories that have come about after he failed to return to the story, with some believing he could have been on a mission for Maeve in another realm—such as the ACOTAR or Crescent City worlds. His characters' whereabouts leave an opening for Maas to re-enter the narrative and finally give his arc some substance.

2 Aelin's Friendship With Dorian & Chaol

Their Goodbye In Kingdom Of Ash Was So Emotional

The series opens and closes with Aelin, Dorian, and Chaol at each other's sides—and their final goodbye in Kingdom of Ash is incredibly emotional. The trio has been through a lot together, and none of it would have even begun if Dorian hadn't decided to choose Celaena as his champion. Thankfully, throughout the series, Maas largely focuses on their friendships with one another and gives each character a compelling arc and a strong amount of growth both individually and as a group—but that doesn't mean readers are done with them.

Their friendship should be strong enough to last despite the miles and months that separate them.

If Maas were to continue Throne of Glass, it would be upsetting if she didn't showcase the trio's ongoing friendship or see them interact in any way. They all mean so much to one another, and it's hard to imagine the Throne of Glass world continuing without these other characters being involved in one another's lives. Yes, they are separated now that Aelin rules over Terrasen and Dorian and Chaol are back in Adarlan, but their friendship should be strong enough to last despite the miles and months that separate them.

1 Finding Out Whose Dragon's Eggs Were In The Ferion Gap

Many Think These Belonged To Abraxos And Narene

Throughout Kingdom of Ash's story, there's a small mention of dragon eggs being found in the Ferion Gap—a mountain that lies between the Ruhnn mountains and the White Fang mountains where Erawan trained wyverns for war. However, after mentioning this detail, Maas never again discusses their significance to the narrative, or what it could potentially mean. And since they never came back into play in Kingdom of Ash, many have dismissed the comment as unimportant.

However, some have theorized that these dragon eggs could in fact belong to Abraxos and Narene, who would have been in the vicinity during the time before Manon and The Thirteen broke off from Maeve's army. Narene's death at the end of the novel obviously had a major impact on Abraxos, but if Maas was hinting that the eggs were theirs, it would be a really sweet way to carry on her legacy and provide Abraxos with a family. Either way, Maas should definitely address the eggs in a future Throne of Glass novel and share their significance with readers.
