However, the queen reserved her deepest and most passionate love for Launcelot. Arthur knew this but because Launcelot was one of his most chivalrous and loyal knights, buried his bitterness inside him. This was the cause of the curse of Camelot. Gwenhyver was the last person who saw Launcelot before departing for the quest for the Holy Grail and told her that he would ask advice from the Lady of the Lake in Ot Moor. When Arthur decided to go and find his knights, he found her in the Queen's Bower. She gave him her last and most beautiful rose to "wear next to his heart" and would guide him.
