The characters play a vital role in delivering that emotional depth.

Let’s explore every major character that makes Sirens of the Deep a standout installment in The Witcher Sirens of the Deep characters saga.

🧝‍♂️ Geralt of Rivia – The White Wolf Returns

No Witcher story is complete without Geralt of Rivia, and in Sirens of the Deep, he’s once again at the heart of the narrative. Voiced by Doug Cockle — the iconic voice actor from the video games — Geralt is hired to mediate tensions between humans and merpeople.

Key Traits:

• Stoic but thoughtful

• Skilled monster hunter

• Struggles with maintaining neutrality

In this story, Geralt is more than just a sword-swinger. He’s a translator, a moral compass, and an observer of love and sacrifice. His neutrality is tested like never before.

🎤 Jaskier (Dandelion) – The Bard with a Broken Heart

Jaskier, known as Dandelion in the books and games, plays a central role in this story. He’s not just comic relief — in Sirens of the Deep, we see a more emotional and vulnerable side of him.

Voice Actor: Joey Batey (Netflix live-action) returns for this version, giving continuity to fans of the series.

Why He Matters:
Jaskier is romantically involved with a key character, and his decisions spark much of the emotional and political tension. His songs also carry narrative weight, telling hidden truths between lines.

🧜‍♀️ Sh’eenaz – The Mermaid at the Center of the Conflict

Among The Witcher Sirens of the Deep characters, Sh’eenaz is arguably the most important new addition. She is a mermaid in love with a human nobleman, Prince Agloval. Their forbidden relationship is the central conflict in the story.

Key Traits:

• Intelligent and emotionally complex

• Torn between two worlds

• Represents the oppressed voice of her people

Sh’eenaz is beautifully animated and voiced with grace and strength, becoming a symbol of love and sacrifice.

👑 King Agloval – The Human Prince with a Choice

King Agloval (referred to as Prince Agloval in the original short story) is a nobleman from a coastal kingdom. He is in love with Sh’eenaz but is torn between his duties to the human world and his heart.

Role in the Plot:

• His union with Sh’eenaz could lead to peace

• Represents political ambition vs. personal love

• Caught between loyalty and desire

His character arc adds a Shakespearean layer to the story — one where the stakes are not just personal, but political.

🧙‍♀️ Yennefer of Vengerberg – A Silent Influence (Rumored)

Though Yennefer doesn’t play a central role in A Little Sacrifice, fans speculate about a cameo in Sirens of the Deep. If she appears, her presence would offer insight into her relationship with Geralt and possibly affect the narrative’s moral decisions.

Potential Voice Actor: Anya Chalotra (Netflix live-action)

Even if limited to flashbacks or brief scenes, Yennefer’s role would deepen the emotional undertones and connect this tale to the broader Witcher universe.

🧜‍♂️ King Gyllen – Ruler of the Merpeople

Another new character introduced in The Witcher Sirens of the Deep characters is King Gyllen, leader of the merfolk. His people have long suffered discrimination and conflict from the surface dwellers. Geralt’s mission is to mediate peace, and Gyllen plays a pivotal role.

Character Depth:

• Powerful and proud leader

• Protective of his people

• Willing to fight or negotiate depending on Geralt’s actions

King Gyllen adds nuance to the merfolk’s side of the story, challenging viewers to question human-centered politics.
