Kasag Fohr was born on Dathomir to Norbia Hja and Fayus Illiun Fohr. Both of them fled from the planet due to persecution by Norbias mother who did not accept the relationship between Norbia and the warrior prisoner from Kodrun. They fled toward Coruscant where the baby named Prumis Dadaos Fohr was then taken in by the Jedi Order. As a youngling he proved to be very talented, and would attract much attention to himself. At age twelve he decided to change his name, since Prumis Dadaos meant "Noble and Superior", and as a Jedi he did not consider himself superior to anyone. So he changed it to Kasag which in the language of his father meant "devoted to others".
