Jaana

Jaana is one of the Companions of the Avatar.

She is based on a real-life friend of creator Richard Garriott. Her real-life counterpart, who holds the same name, is from Finland, where the name is indeed common.

She is a native of Earth, and friend of Lord British. In Britannia Jaana is a Druid, and made her home in the forest town of Yew. In Ultima IV she gladly joined the future Avatar in his/her quest to find the Codex of Ultimate Wisdom.

In Ultima V she was declared an outlaw by Lord Blackthorn, and retreated to a secret location of tunnles deep under Yew, where she worked with the resistance against the Dark Lord's rule. When the Avatar came, she gladly joined him/her on the quest to topple Blackthorn.

By Ultima VI, Jaana again lived in Yew, but the quiet life of a town druid wasn't really for her, and she was horribly bored. So when the Avatar came to Yew to search for the Rune of Justice, she gladly joined the party to assist in the quest of the False Prophet.

In the time of Ultima VII, which played 200 years after the gargoyle war, Jaana had moved to the town of Cove, to work there as a healer, and was in love with the town's mayor, Lord Heather. Like all magic in Britannia, hers failed because of the disrupted ether, caused by the Guardian's generator, but she stayed sane. Joining the Avatar's party when he/she came to town, Jaana went on the quest to stop the Guardian from entering Britannia. She was able to offer healing services, but it exhausted her, with the Ether in disarray.

In Ultima IX Jaana was seduced to service in the Wyrmguard, where she came under the control of the Guardian. The Avatar was able to free her, and she would later assist him in the final battle against his archnemesis. - However, this is seen as uncanon.

Trivia

 * Her character portrait in Ultima VI is REALLY horrible. Thankfully the designers decided to give her a much younger and better apperance in Ultima VII.
 * Because of a bug, she can't do magic in Ultima VII, even after the Ether is restored.
