The Code is Cracked!

You may recall, the Land of Numeria.  Today Clarity finished learning her numbers.  She has traveled through The Land of Numeria, each day learning a new number.  Today she learned number 12.  After she completed her last number she received a golden scroll and a locked box. In order to open the locked box she had to write all of the numbers on the golden scroll and the last three numbers cracked the code of the box. 
She quickly worked through the scroll and in no time she was able to open the box.  Inside of the box was the real Land of Numeria and Adira and Phaedra. (the two characters in the story)

Twelve is the numbers
That charts space and time
Twelve inches make one foot
Twelve months the year’s signs
Twelve hours of day
Twelve hours of night
When we think of twelve
All the world’s made right.
