Laurana

Laurana is the court magician of Castle Britannia during Ultima IX.

The Avatar met her in her laboratory, where she told the hero of the recent troubles Britannia was experiencing with magic, explaining how to get spells into a Spellbook. She also allowed the Avatar to freely take everything needed from her laboratory and use her binding circle.

Trivia

 * That her laboratory can only be reached by a teleporter in Lord British's bedroom is a weakness in the world building and had given some fans interesting ideas...
