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".
Modron Sigrdrifa is the high priestess at the Temple of Freyja on Hindarsfjall. She is described as having fair and pale eyes, and an oval, none too pretty and rather unfeminine face. She is almost as tall as Crach an Craite, making her a full head taller than Yennefer. She is also either extremely perceptive, or telepathic as she responded directly to Yennefer's inner musings.
