Sh'eenaz was a mermaid who fell in love with a human duke, Agloval. Agloval asked Geralt to convince Sh'eenaz to give up her life in the ocean to join him on land, but the witcher failed to convince her. However, through a series of events where other underwater dwellers and the humans in the area almost went to war, it's narrowly avoided when Sh'eenaz agrees to give up her tail and walks on land to marry her lover.
- In The Witcher when Geralt meets the Lady of the Lake, the latter tells him that she has heard of the witcher "on good authority", meaning that she has heard it from Sh'eenaz.
- ↑ 1.0 1.1 The Polish language uses mermaid to also mean siren. It was later clarified in The Witcher 3: Wild Hunt Artbook, in particular the Polish version, that the game's sirens are actually "nixa" and often get mistaken for real sirens (in English: mermaids). A notable difference though is that nixa have wings.
