It tells how in the time of the Crusades, Elynas, the King of Albany (an old name for Scotland or Alba), went hunting one day and came across a beautiful lady in the forest. She was Pressyne, mother of Melusine. He persuaded her to marry him but she agreed, only on the promise—for there is often a hard and fatal condition attached to any pairing of fay and mortal—that he must not enter her chamber when she birthed or bathed her children.
