One of the Air element protectors comes to check on the air element orb that will most likely break open to reveal one of the four elements that will help end the thousand-year- war between the 4 nations.

He sees that there is a crack in the air orb. He gets nervous as it may be too soon for the air element to hatch so he gets the king of the air nomads. The king looks at the orb and asks one of the protectors, "How long has it been since it had its last crack?"
