Task: Question Generation
Input (English):  Clig s begins with the story of his parents, Alexander and Soredamors. Alexander, the son of the Greek emperor (also called Alexander), travels to Britain to become a knight in King Arthur's realm. While at court, Alexander gains favor with King Arthur, is knighted, and assists in retaking Windsor Castle when it is taken by the traitor, Count Angr s. During his time at court, Alexander meets Arthur's niece, Soredamors and falls in love but is unable to express his feelings to her. She feels the same, but neither party is able to tell the other how they feel. Queen Guinevere takes notice and encourages them to express their mutual love. They immediately marry and a child is born. This child is Clig s. Alexander and his family then return to Greece and find out that Alexander's brother, Alis, has claimed the throne to Greece since their father has died. Although Alexander is the rightful heir to the throne, he concedes to Alis with the condition that Alis will not marry or have children so that the throne will pass to Clig s. Alexander dies and Clig s is raised in Greece. Many years after Alexander's death, Alis is persuaded to marry and he chooses the daughter of the German Emperor, Fenice. Thus begins the story of Clig s and Fenice. Clig s falls in love with his uncle Alis' wife. She also loves Clig s but he follows in his father's footsteps to Arthur's kingdom to be knighted. Like his father, he does well in King Arthur's court, participating in tournaments and displaying courtly manners. He is knighted and returns home. Clig s and Fenice still love each other and Fenice concocts a plan to use magic to trick Alis to escape. Using the magic of her governess, she fakes her death so that she and Clig s can runaway together. They succeed and hide in a tower but are found by Bertrand, who tells Alis; Clig s goes to Arthur to ask for help in getting his kingdom back from his uncle, but Alis dies while he is away. Clig s and Fenice are free to marry and Clig s is now emperor.
