"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.
