Chapter IV:

Mordred was Arthur's son-nephew by Morgause.. Many years passed, and the King and Queen lived happily together. Under the King's wise leadership, Camelot prospered, and her people were happy.

One day, four strangers came to the gates of Arthur's castle. Standing on the parapets with Merlin, he looked down at them. There were three women and a boy of about fourteen.

“Who are they?” asked Arthur.

“The women are your half sisters by your father, Uther Pendragon,” Merlin told him. “Two of them have come to make their peace with you. But the third, Morgan le Fay, is evil. She seeks your downfall. I hoped never to see her in Camelot.”

Then Arthur looked at the boy. “Who is he?” he asked.

“You don't want to know,” Merlin warned. But Arthur insisted.

“He is your son by your half sister, Morgause. She was the woman who came to you that night. It was Morgan le Fay who planned his conception with magic. She will use him against you. He will betray you.”
