What Happens at the End of The Witcher: Sirens of the Deep?

How The Witcher: Sirens of the Deep (2025) ends, what the final scene means, which earlier moments set it up and how to read the ending if the film leaves it open. The full ending explained, with every spoiler.

In the ending of Sirens of the Deep, the true villain behind the conspiracy to spark war between humans and merpeople is revealed to be Melusina, the niece of Sh’eenaz’s evil aunt. Driven by a desire for revenge against her sister Dahut, who had stolen her lover Basim and failed to give him a child, Melusina resorted to dark magic and transformed into a sea monster, the Kraken, to threaten both kingdoms. During the chaos, Geralt intervened, risking everything to expose her plan and defeat her. With Melusina dead, the immediate threat was eliminated, and peace was temporarily restored, with Dahut healing Sh’eenaz’s injuries using her magic.

However, Agloval, the young prince of Bremervoord who loved Sh’eenaz, made a profound sacrifice. He chose to drink a magical potion that transformed him into a merman, renouncing his human identity and his throne, to be with her. His decision was driven by the understanding that true love means sacrifice, and he was willing to give up his kingdom and humanity for a chance at a life together with her. His father, King Usveldt, disapproving and feeling betrayed, was left bitter, especially after losing his illegitimate son Zelest in battle and witnessing his son Agloval's departure.

In the final moments, Geralt, sensing that the conflict might not be completely over, warns that King Usveldt is likely planning another attack on the merpeople, hinting that violence may continue. Meanwhile, Agloval and Sh’eenaz finally unite, embracing the hope of a peaceful life together, away from war and hatred. Geralt then departs for new adventures, ending the story with the implication that, though peace has been achieved for now, tensions between humans and merpeople could flare up again.

On a more personal note, Geralt’s feelings for Yennefer linger in the background. As he and Jaskier set out toward Caingorn, Geralt's encounter with Yennefer remains unresolved—for now, he’s heading into his next story, perhaps to meet her again someday, leaving the door open for future reunion. This ending underscores themes of sacrifice, love, and the hope for peace despite the persistent shadows of conflict.

Movies with bittersweet heroic endings like The Witcher: Sirens of the Deep

Stories where heroic duty demands personal sacrifice, leading to poignant endings. If you liked the bittersweet ending of The Witcher: Sirens of the Deep, explore these films where heroes make profound sacrifices. These dark fantasy and action dramas feature heavy emotional weight, tragic elements, and endings where duty or fate overshadows personal happiness, much like Geralt's story.

  • melancholic
  • sacrifice
  • bittersweet ending
  • loner hero
  • Tone: dark, tragic, bittersweet
  • Pacing: fast, driven
Why these movies?

The story pattern: The narrative follows a heroic figure who succeeds in their external mission—saving a village, brokering peace—but fails to secure their own happiness.

Why they belong together: This thread connects movies based on their emotionally resonant, bittersweet conclusions. The shared experience is the heavy feeling left by a story where heroism doesn't equate to a happy ending, focusing on the theme of sacrifice for a cause greater than oneself.
