The Well at the World's End

The Well at the World's End is a high fantasy novel by the British artist, poet, and author William Morris. It was first published in 1896 and has been reprinted regularly ever since.
Using language with elements of the medieval tales which were his models, Morris tells the story of Ralph, the youngest son of King Peter of Upmeads. Their kingdom being rather humble, Ralph and his three elder brothers are bored of the provincial life, so one day they request permission from their father to explore the world. The king allows the three eldest sons to depart, but bids Ralph to stay to ensure at least one living heir. Ralph, desperate for adventure and against his father's will, sneaks away.
