'The Witcher: Blood Origin' finale teases Henry Cavill's 'heroic sendoff' in the upcoming season of 'The Witcher'

"The Witcher: Blood Origin," the prequel fantasy series to "The Witcher," follows a band of seven warriors on a quest to stop a powerful elven empire.

Upon realizing that the villains have a beast with insane strength from another world, the band of heroes decides to enhance one of their own in order to defeat the beast.

Thus, they create the prototype for a witcher, the name of powerful augmented warriors tasked to fight monsters in "The Witcher" world. At first, they are successful in turning Fjall (Laurence O'Faurain) into a stronger, enhanced warrior.

The heroes — Fjall, Meldof (Francesca Mills), Scian (Michelle Yeoh), Syndril (Zach Wyatt), Zacaré (Lizzie Annis), Éile (Sophia Brown), and Brother Death (Huw Novelli) — are victorious in the season finale, titled "Of Mages, Malice and Monstrous Mayhem." Still, their victory soon takes a turn.

During the final battle, Fjall's monster transformation takes over him, and his lover Éile is forced to kill him. When Syndril breaks the monoliths — giant statues that can be used to travel through time, space, and to other worlds — different worlds collide with each other separating people from their world.

"The Witcher" main series centers on Henry Cavill's Geralt, who slays monsters in an effort to protect Ciri (Freya Allan), with whom he has a spiritual connection.

"The Witcher" showrunner Lauren Hissrich recently told Entertainment Weekly that the upcoming third season of the main series will have a "heroic sendoff" for Geralt before Cavill departs from the franchise.

The ending of "The Witcher: Blood Origin" may hint at what that "heroic sendoff" might entail.

"The Witcher: Blood Origin" is set in a time where elves rule the world and humans are nowhere to be seen. If you've seen the main "The Witcher" TV adaptation that airs on Netflix or played any of the popular games, you will know that the opposite is true in the present-day "Witcher" universe. 

This change is explained in the finale. When the monolith was destroyed, multiple worlds collided in an event called "the conjunction of the spheres," creating a world that now has monsters and humans as well as original elves and dwarves.

Since the 2018 premiere episode of "The Witcher," monoliths have become an increasingly important part of the story.

We learn in 2021's season two that Ciri (Freya Allan) is one of the few people that can use them due to her elder blood, a special gene that granted a person powerful magic. So showing the destruction a monolith can cause, raises the stakes for "The Witcher" season 3 if Ciri is not able to control her ability.

Speaking about other worlds, the finale also gives an origin story to the Wild Hunt.

In the season two finale of "The Witcher," the lead heroes Geralt, Ciri, and Yennefer (Anya Chalotra), accidentally travel to a different world while trying to get rid of a demon.

While there, they encounter the Wild Hunt, also known as the Wraiths of Mörhogg who try to capture Ciri because of her elder blood. The heroes barely escape back to their world but it is likely that this won't be the last we hear of the Wild Hunt.

"The Witcher: Blood Origin" finale shows that the Wraiths are just elves cast off to a different world by the sorcerer Balor (Sir Lenny Henry).

It is likely that their agenda for Ciri is to use her abilities to return to their old world after being trapped in a different world for so long.

In the finale, Fjall and Éile have sex after he had been transformed by the wizards into the prototype Witcher.

When Éile is revealed to later be pregnant with Fjall's child, it is implied that the child would be different due to Fjall's transformation. In the final moments of the episode, Éile asks an oracle called Ithlinne (Ella Schrey-Yeats) about what the future holds for her unborn baby.

Ithlinne says: "The Time of the Spheres is upon us. Aen Seidhe lost across the skies. Cast adrift in time. Ever Searching for love, lost and left behind. The Lark's seed shall carry forth, the first note of a song that ends all times and one of her blood shall sing the last."

The first section of the prophecy appears to be referring to "the conjunction of spheres," the event where the different worlds collided with each other. Aen Seidhe is the name of the elves we see in the miniseries, which means that the first part about being "lost across the skies" refers to their people being separated into different worlds.

However, the last section focuses on Éile's child and her descendants. In episode one, Éile is revealed to be a traveler that the people call the Lark, which means "The Lark's seed" must refer to her child.

Fans do not get to see Éile's child before the series ends but the baby is likely Ciri's ancestor from the main "Witcher" series. In the finale's final moments, the narrator of the series says that Éile's child's blood had been warped because Fjall had been transformed when they had sex.

It's likely that the child has elder blood, or at least an early version of it. If this prophecy is anticipating an extremely powerful descendant, Ciri is the only character that comes to mind since she's been the focus of the main series.

If Ciri is Éile's descendant, the last part of the prophecy, "one of her blood shall sing the last," may be teasing the character's journey in season 3 of "The Witcher."

In previous seasons of the show, Ciri has shown herself to be incredibly powerful but not have a lot of control over her abilities.

With multiple parties trying to capture or kill Ciri at the end of season two, it wouldn't be unbelievable to think that a villain might use her abilities to destroy the world. Alternatively, due to the naivety of her abilities, Ciri could accidentally do it herself.

Either way, the ending seems to be setting up a finale where Geralt may have to stop his mentee Ciri from destroying the world. The idea that Ciri will be the final obstacle appears to be hinted at in both Ciri's origins in "The Witcher" books and in recent comments by the series' showrunner.

Hissrich told Entertainment Weekly that season three will take inspiration from "Time of Contempt," the fourth book in author Andrzej Sapkowski's "Witcher" series. This is the book where Ciri learns her prophecy that she will save the elves from the destruction of the old world. Hence, there is already precedence for her character being linked to destruction.

Hissrich also said in the interview that the story will be a "heroic sendoff" for Cavill's last appearance as Geralt and the character will have a new mission in season four.

What more of a "heroic sendoff" can there be than Geralt literally trying to stop the end of the world?

In addition, if this is the end of the elder blood arc then it is likely something major will happen to Ciri.

The post-credit scene of "Blood Origin" leaves one more mystery to be solved in season 3 of "The Witcher."

The prequel series introduces Avallac'h, a young elf wizard, who tries to learn how to use the Monoliths to teleport to other worlds.

In the post-credit scene, Avallac'h is seen 1,500 years in the future watching a young Ciri play in the streets. Unless the mage, or magician, somehow gained immortality, it is likely that he finally learned how to use the monoliths to travel in time.

On the one hand, this could mean the character could help Ciri learn to control her powers. However, in both the book series and the video game "The Witcher 3: Wild Hunt," which was released in 2015, Avallac'h has not been a very trustworthy character.

Whatever his reason for being in the future, it's likely the character will return in the next season of "The Witcher." 

"The Witcher" season 3 is set to premiere in 2023.
