The Witcher wiki now has a light themed alternative for the wiki skin. To check it out, go to Special:Preferences, then choose the "Appearance" tab and click on the radio button next to "Hydra".
Water sprites are one type of sprite; creatures which can be found in the vicinity of Lower Posada, if folklore is to be trusted. They are mentioned in passing by Dandelion as he tries to convince Geralt that there is still plenty of work out there for witchers. Geralt is not so sure.
|“||What are you talking about? What civilisation? I crossed the Buina a week ago and heard all sorts of stories as I rode through the country. Apparently there are water sprites here, myriapodans, chimerea, flying drakes, every possible filth. You should be up to your ears in work.
Stories, well, I've heard them too. Half of them are either made up or exaggerated. No Dandilion. The world is changing. Something's coming to an end.
