Question: What fictional character is the first creature Lucy meets in Narnia in the first scene of Narnia described in "The Chronicles of Narnia"?
Context: Anvard is the moatless castle where King Lune of Archenland resides in the fictional land of Narnia, as described in "The Chronicles of Narnia", a book series by C. S. Lewis.  It is made of red-brown stones and sits on a green lawn in front of a high woody ridge.  In "The Horse and His Boy", Prince Rabadash led a force of two hundred Calormene horsemen in a surprise attack against it, but was defeated by a relief army from Narnia led by King Edmund. Prince Caspian (also known as Caspian X, King of Narnia, Lord of Cair Paravel and Emperor of The Lone Islands, Caspian the Seafarer, and Caspian the Navigator) is a fictional character in "The Chronicles of Narnia" by C. S. Lewis.  He is featured in three books in the series: "Prince Caspian", "The Voyage of the Dawn Treader", and "The Silver Chair".  He also appears at the end of "The Last Battle". Lantern Waste is a fictional place in "The Chronicles of Narnia" series by C. S. Lewis.  It is a wood and is notable as the place where Lucy Pevensie and Mr. Tumnus meet, which is the first scene of Narnia described in the books.  The lamppost in the wood is an iconic image of Narnia, and the question of its origin is what convinced Lewis to write more than one book on Narnia.  One of King Edmund's titles is "Duke of Lantern Waste". King Tirian (born between 2530 and 2535, Narnian time) is a fictional character from C. S. Lewis's fantasy series "The Chronicles of Narnia".  He is the protagonist of "The Last Battle", in which he is the last King of Narnia, who has to defend his kingdom against subversion and invasion.  He is well respected by the Narnians, and a skilled swordsman.  He is descended from Prince Caspian, and is the son of King Erlian.  His closest friend is Jewel the Unicorn. Cair Paravel is the fictional castle where the Kings and Queens of Narnia rule in "The Chronicles of Narnia".  It is the location of the four thrones of High King Peter the Magnificent, High Queen Susan the Gentle, King Edmund the Just, and Queen Lucy the Valiant. 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"). Aslan's Country is a fictional location from C. S. Lewis' "The Chronicles of Narnia" series.  It is the home of Aslan, the great lion.  It is described as a series of mountains, thousands of feet high, but without snow or ice.  Instead, Aslan's Country has a clear blue sky, lush green grass, colourful birds, and beautiful trees.  There are entrances to Aslan's Country from all worlds, including Narnia and Earth.  It is located beyond Narnia's rising sun at the eastern edge of the world, and indeed rings around the whole Narnian world. Susan Pevensie is a fictional character in C. S. Lewis's "The Chronicles of Narnia" series.  Susan is the elder sister and the second eldest Pevensie child.  She appears in three of the seven books—as a child in "The Lion, the Witch and the Wardrobe" and "Prince Caspian", and as an adult in "The Horse and His Boy".  She is also mentioned in "The Voyage of the Dawn Treader" and "The Last Battle".  During her reign at the Narnian capital of Cair Paravel, she is known as Queen Susan the Gentle or Queen Susan of the Horn.  She was the only Pevensie that survived the train wreck (because she was not on the train or at the station) on Earth which sent the others to Narnia after "The Last Battle". The First Battle of Beruna is a fictional battle in C. S. Lewis' fantasy series "The Chronicles of Narnia".  It is fought in Narnia at the edges of the Great River near the Fords of Beruna, in the year 1000 according to Lewis' Narnian timeline.  It is the climactic battle of "The Lion, The Witch and The Wardrobe" and one of several battles in the Chronicles of Narnia. Tumnus is a fictional character in C. S. Lewis' series "The Chronicles of Narnia".  He is featured prominently in "The Lion, the Witch and the Wardrobe" and also appears in "The Horse and His Boy" and "The Last Battle".  He is close friends with Lucy Pevensie and is the first creature she meets in Narnia, as well as the first Narnian to be introduced in the series.  Lewis said that the first Narnia story, "The Lion, the Witch and the Wardrobe", all came to him from a single picture he had in his head of a faun carrying an umbrella and parcels through a snowy wood.  In that way, Tumnus was the initial inspiration for the entire Narnia series.
Answer: Mr. Tumnus
