The second half of The Well at the World's End (Books Three and Four)
Using language with elements of the medieval tales which were his models, Morris tells the story of Ralph of Upmeads, the fourth and youngest son of a minor king, who sets out, contrary to his parents' wishes, to find knightly adventure and seek the Well at the World's End, a magic well which will confer a near-immortality and strengthened destiny on those who drink from it. The well lies at the edge of the sea beyond a wall of mountains called "The Wall of the World" by those on the near side of them but "The Wall of Strife" by the more peaceful and egalitarian people who live on the seaward side.
Ralph meets a mysterious lady who has drunk from the well, and they become lovers. Together and separately, they face many foes and dangers including brigands, slave traders, unscrupulous rulers and treacherous fellow travellers. The lady is killed, but with the help of Ursula, another maiden whom Ralph meets upon the way, and the Sage of Sweveham, an ancient hermit who has also drunk of the well, Ralph eventually attains the Well, after many more adventures. The outward journey takes more than a year. Returning from the well, Ralph, Ursula and the Sage find that some of the poor oppressed folk they had helped on the way to the well have righted grave wrongs, increased prosperity and reduced the level of strife in the city-state kingdoms along the way. The wayfarers must now decide whether they can settle down to a righteous but stodgy life at Ralph's home kingdom now that they have learned so much and become near-immortal, or are called to further heroism in the wider world.
