"The Billios Family's Tradition" 

The Billios Family was a large family, larger than the Sloan Family but the main family was actually not that much. 

There were a lot of branch families but unlike the Sloan Family who kept the branch families with the main family before Ainsley became the family head...

The Billios Family branches were scattered throughout the country, mainly to strengthen the Billios Family's influence everywhere. 

Other elite forces basically did this too, but the Billios Family had a firmer bond between the main family and their branch families. 

Everyone was close to each other because all the children, whether they were from the main family or branch families, had to live in the capital until they were eighteen years old.

They were basically separated from their parents if their parents were the leaders of the branch families. 

But the parents usually visit their children on weekends.
