Born into the Great House of Nalju on Serenno, Ethan grew up as one of the younger sons in the family. While he did not live a hard life, he was not spoiled nearly as much as his other brothers. He knew that his father had always meant for him to be a soldier. So, at the age of 8, he began to train with Masters of both Teras Kasi and Echani Martial Arts. While studying under these masters, he also learned to master weapons from a Mandalorian who had been hired to teach him how to fight like a Mandalorian.
