Context: The Lion, the Witch and the Wardrobe is an American dramatization of "The Lion, the Witch and the Wardrobe" by C.S. Lewis, the British children's novel that inaugurated "The Chronicles of Narnia" in 1950.  The one-act play for two actors was written by Le Clanché du Rand and published in 1989 by Dramatic Publishing of Woodstock, Illinois.  It is licensed by Dramatic to theaters worldwide.  One production opened in 2011 Off-Broadway in New York City. The Hundred-Year Winter is a time period in the fictional Narnia universe created by C.S. Lewis.  It takes place from 900–1000 Narnia time.  The White Witch Jadis cast a spell to make it Winter all year round, but never reaches Christmas.  But throughout the story, Aslan is entering Narnia and his presence weakens The White Witch, Jadis, causing Spring and Father Christmas to slowly appear.  Aslan also brings Peter, Lucy, Susan, and Edmund to Narnia to fulfill the Prophecy of The Four Thrones ("When two daughters of Eve and two sons of Adam sit together in throne at the Cair Paravel, the reign of the White Witch will be over and done.)  This would put an end to White Witch's plan and her reign and the endless winter would come to an end.  (The final days of the Hundred Year Winter occur during "The Lion, the Witch, and the Wardrobe".) Laura Miller is an American journalist and critic based in New York City.

Lewis' "The Chronicles of Narnia" books: Clive Staples Lewis (29 November 1898 – 22 November 1963) was a British novelist, poet, academic, medievalist, literary critic, essayist, lay theologian, broadcaster, lecturer, and Christian apologist.  He held academic positions at both Oxford University (Magdalen College, 1925–1954) and Cambridge University (Magdalene College, 1954–1963).  He is best known for his works of fiction, especially "The Screwtape Letters", "The Chronicles of Narnia", and "The Space Trilogy", and for his non-fiction Christian apologetics, such as "Mere Christianity", "Miracles", and "The Problem of Pain". William Thompson Kirkpatrick (10 January 1848 - 22 March 1921) was an Irish teacher and grammar school headmaster.  He is best known for having been the tutor of the two Lewis brothers from Belfast, Warnie Lewis and C.S. Lewis.  C.S.

In his autobiography, Lewis reports that he was significantly influenced by his tutor. The Seven Great Lords of Narnia are fictional characters in The Chronicles of Narnia by C. S. Lewis.  They are briefly mentioned in "Prince Caspian" and are central to the plot in "The Voyage of the Dawn Treader", the second and third published books, respectively, in the series. Lucy Pevensie is a fictional character in C. S. Lewis's "The Chronicles of Narnia" series.  She is the youngest of the four Pevensie children, and the first to find the Wardrobe entrance to Narnia in "The Lion, the Witch and the Wardrobe".  Of all the Pevensie children, Lucy is the closest to Aslan.  Also, of all the humans who have visited Narnia, Lucy is perhaps the one that believes in Narnia the most.  She is ultimately crowned Queen Lucy the Valiant, co-ruler of Narnia along with her two brothers and her sister.  Lucy is the central character of the four siblings in the novels.  Lucy is a principal character in three of the seven books ("The Lion, the Witch and the Wardrobe", "Prince Caspian", and "The Voyage of the Dawn Treader"), and a minor character in two others ("The Horse and His Boy" and "The Last Battle"). The Second Battle of Beruna is a fictional battle in C.S. Lewis's fantasy series The Chronicles of Narnia between the "Old Narnians" and the Telmarines of Narnian.  It is one of several battles in the Chronicles of Narnia. The Beginning Place is a short novel by Ursula K. Le Guin, written in 1980.  It was subsequently published under the title "Threshold" in 1986.  The novel does not belong to any of the cycles for which Le Guin is well known.  The story's genre is a mixture of realism and fantasy literature.  The novel's epigraph "What river is this through which the Ganges flows?"  is quoted from Jorge Luis Borges.  The novel has been subject to critical studies comparing it to C.S. Lewis' "The Chronicles of Narnia", Lewis Carroll's "Through the Looking-Glass" and William Shakespeare's "As You Like It".
