Sh'eenaz

Sh'eenaz is a siren or mermaid who fell in love with a human prince, Agloval in the short story "Trochę poświęcenia" ("A bit of Dedication"). In this story, the prince initially hires Geralt to convince Sh'eenaz to abandon her home in the sea to live with him on land.

When Geralt meets the Lady of the Lake, the latter tells him that she has heard of the witcher "on good authority", meaning from Sh'eenaz.
