Sheila

Sheila is a solemn ranger who may be found at Castle Britannia during Ultima IV.

Description
Sheila could be found at Pendragon's Royal Healer. Should the Stranger speak with her, she would claim to be in search of her own inner light and would assist the hero in their own quest by describing the use of the shrines and the necessity of the runes and mantras for meditation.

Trivia

 * In the Nintendo remake of Ultima IV (where most character names were omitted and dialogue was significantly modified), Sheila can be identified with the woman in the same room, who simply encourages the Stranger.
