Event on Pirate Utopia

As you approach the gates of the Ice Palace, one of your troops points in terror. You watch in awe as great slabs of ice separate from the castle walls with loud cracking reports and crash to the ground. Soon the ice is gone and the sun begins to peak through the gloom. The deathly silence that must have ruled these lands for centuries ends as birds begin to sing. From inside you hear the sounds of life.
