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. She gave birth to triplets. When he violated this taboo, Pressyne left the kingdom, together with her three daughters, and traveled to the lost Isle of Avalon.
