The Witcher: Sirens of the Deep is a new animated project from Netflix that'll explore one of Andrzej Sapkowski's short stories, A Little Sacrifice. In an interview with SFX magazine (via GamesRadar), writer Mike Ostrowski discussed what fans can expect from this movie including a neat little easter egg.
Sirens of the Deep is set in the middle of episodes five and six from Season 1 and will follow Geralt and Dandelion in the port town of Bremervoord, making peace between land dwellers and merfolk. Episode five is when Geralt meets Yennefer for the first time in the mayor of Rinde's house, which is the start of the long and slightly rocky relationship.
