The start of the numbers is only started with those who have been selected by the Nation Wide group of the King's Tablero who runs the selection process. Once you have been chosen you will be evicted from your family and one of the two parents you have can choose to take the trials to earn you back or leave you there to learn mannerism. In 001 a young girl by the name of Arianna Reid is chosen to become the first number of the second generation. A much more "civilized" set of numbers. Her mother was evicted as well as she was a previous number and an incredibly smart individual while her father proceeded to go through the trials to get her, her mother and her twin brother back from the grasp of the Tablero's judgement. He fails and Arianna and her family stay in the hold of the Tablero and thus are there for a couple years until Arianna and the other six children are released back into society. It causes many many problems for them, therefore, we head into the structure.
