The Witcher will return for a third season in June.
The Witcher is a fantasy drama based on the Andrzej Sapkowski book series, which was previously adapted as a series of video games.
The TV series follows Geralt of Rivia (Henry Cavill), a monster hunter known as a Witcher, as he strives to protect Ciri (Freya Allan), a princess with powerful magic.
The teaser hints at big changes for Geralt (Cavill), Ciri (Allan) and the sorceress Yennefer (Anya Chalotra).
"Now, for the first time, I understand real fear," Geralt says.Netflix also shared a poster featuring Geralt, Ciri and Yennefer with the caption "Family's worth fighting for."
Netflix previously released a poster that shows Geralt and Yennefer embracing Ciri.
News broke in October that Cavill will exit The Witcher after Season 3, with Liam Hemsworth to replace the actor as Geralt in Season 4.
