Wind in the Door, Proginoskes takes Meg to "yesterday" to show her the Echthroi destroying a patch of stars. Charles Wallace spends most of A Swiftly Tilting Planet "Within" the bodies and minds of people from the past, traveling there by a winged unicorn. Many Waters finds Sandy and Dennys stranded in the time of Noah after using their father's computer while an experiment is in progress. The world of L'Engle's characters is filled with fictional place names, often taken from mythological figures that relate symbolically to the locale. For example, the planet Ixchel in A Wrinkle in Time, where Meg is cared for by a motherly sightless creature with tentacles, is named for Ixchel, a Mayan moon goddess. Other, more mundane locations are often fictionalized versions of places L'Engle has lived or visited in the real world, such as L'Engle's Connecticut home, which strongly resembles that of the Murry family. Characters The main characters (protagonists) in the Time Quintet are: Margaret "Meg" Murry is the eldest child of scientists Alex and Kate Murry. Mathematically brilliant but less than adept at other subjects in school, Meg is awkward, unpopular, and defensive around authority figures, but gets along well with her family and friend Calvin O'Keefe. Meg is initially unhappy with her physical appearance, particularly her unruly hair, braces and glasses. She outgrows most of these limitations in the course of the books, although she never completely overcomes her inferiority complex. By the time of A Swiftly Tilting Planet she is married to Calvin and expecting her first child who is revealed to be Polly in An Acceptable Time. Charles Wallace Murry is the youngest Murry child, described by his mother as "different" and "new." Charles Wallace did not talk at all until he was nearly four years old, at which time he began to speak in complete sentences. Charles can empathically and telepathically "read" certain people's thoughts and feelings, and is extremely intelligent. Calvin O'Keefe is the third eldest of Paddy and Branwen O'Keefe's eleven children, a tall, thin, red-haired 14-year-old high school junior (as of the first book) who plays on the school basketball team. Neglected by his own family, Calvin joyfully enters the lives of the Murrys. By the time of A Swiftly Tilting Planet he is married to Meg, holds two doctorates, and is presenting an academic paper on chordates. Alexander "Sandy" and Dennys Murry — Younger
