A gentle healer in the children's story The Elysian Kingdom, the role into which Christine Chapel is cast in 2259 when a nebula entity transforms the Enterprise.
Lady Audrey is a character in the book The Elysian Kingdom, which Joseph M'Benga reads to his daughter Rukiya while she is out of the transporter buffer. In the first-season Strange New Worlds episode named after the book, an intelligence in the Jonisian Nebula casts the whole crew in the story.
Nurse Christine Chapel becomes Lady Audrey, a healer who tends the wounded with herbs and soft words in what used to be sickbay. She treats M'Benga as King Ridley and has no idea that she is a Starfleet nurse.
M'Benga and Hemmer, the only two unaffected, pass through her care as they try to work out what has happened to the ship. When the entity finally lets the crew go, Chapel returns to herself with no memory of her time in the tale.
