It was a family tradition,ever since a 2 brothers that were force sensitive were born, to have 2 kids that are force sensitive and to give one to the Jedi and let the other marry. This way the Kudeb/Rakor clan could grow bigger and the Jedi given would have an uncle who was also a Jedi. This Tradition was broken when Gyasz Kudeb's parents only had one kid. this would have ended the family if Gyasz Kudeb Sr. did not have a kid, although this broke the rules and a kid was born, Gyasz Kudeb Jr. had no brother or sister and wasn't that force sensitive. But he now had a Dad and a great uncle as a Jedi to help mentor him as he grows up and then as a final test, Gyasz Kudeb Jr. must escape the great Jedi purge, find a wife, and have 2 force sensitive kids in order to keep the family and tradition
