The Chatwins

The Chatwins are a family of five siblings who travel to Fillory while being sent away to the country; their descriptions of these travels to Christopher Plover form the basis of the "Fillory and Further" novels. They are listed in order of age.

• Martin Chatwin, also known as the Beast, is the eldest sibling and first to travel to Fillory. He features in "The World in the Walls" and appears at the end of "The Flying Forest". Christopher Plover sexually abuses him, and he becomes disillusioned with the real world. He is able to sneak back in to Fillory through a route intended for Rupert, and he gives his humanity to Umber to be able to remain in Fillory forever. He becomes the Beast, rules Fillory as a tyrant, and is killed by Alice.
• Fiona Chatwin features in "The World in the Walls" and "The Flying Forest", and later has children who inherit the house in Cornwall. In her later life, she would pretend she'd never heard of Fillory.
• Rupert Chatwin is the author of "The Door in the Page" and the great-grandfather of Plum Purchas. He features in "The Girl Who Told Time", "The Flying Forest", and "The Secret Sea". He witnessed Martin giving his humanity to Umber in Castle Blackspire, after which he stole a spell and a knife capable of killing gods. He left the spell, the knife, and a memoir called "The Door in the Page" in a briefcase that could only be opened by one of his descendants before he was killed in Africa in World War II; this memoir is included in The Magician's Land.
• Helen Chatwin features in "The Girl Who Told Time" and "The Wandering Dune". She is described as pious, worshipping Ember and Umber and deferring to Their judgement. After she and Jane receive magic buttons that would allow them to travel to Fillory at will, she hides them in a well. Later, she changes her name, becomes an Evangelical Christian, and moves to Texas.
• Jane Chatwin, also known as the Watcherwoman, is the author of "The Magicians," intended to be the sixth "Fillory and Further" book. She features in "The Wandering Dune" and "The Secret Sea". After she finds the magic buttons again at around age 13, she returns to Fillory to be told Martin has become the Beast and that Umber has been killed. She holds a war council with Ember. The dwarves give her a watch that allows her to travel in time, and she attempts many different scenarios until Quentin and his friends are finally able to kill the Beast, after which she destroys the watch. Following this, she ages rapidly. Posing as a paramedic, she is responsible for giving Quentin the note that leads him to his Brakebills entrance exam.
