1. Ygraine was at her spinning wheel in the castle Tintagel when she had a vision. Her sister, Morgause, was hoping for a revelation about herself. Ygraine's daughter, Morgaine, was concerned for Ygraine's well-being. What was Ygraine's vision?
From Quiz The Mists of Avalon
Answer:
The Lady of the Lake and the Merlin of Britain were arriving
Morgaine was startled by the sight of her mother in a trance, and Morgause, who was still single at this point in the story, was hoping that the vision included a husband or lover for herself. However, more information was coming. The two visitors told Ygraine that she was going to marry a man who wore the sign of the dragon and bear a High King of Britain. When Morgause asked to take her place, since Ygraine was married, Viviane (the Lady of the Lake) snapped at Morgause to be content because there would be a king and sons in the future for her.
