One for sorrow

They won't teach you this in your history class,
but once there was a legend
of a queen who was only a lass.
Of two dragons, light and dark
and a swift warrior
who couldn't stay behind.
King of darkness
Queen of magic lands
King and Queen find each other
How long will it last?

(Part three of my three part mericcup story.
Part one: Of axes and dragons.
Part two: The queen and the chief.)
