Erastik Trapp was a male Kotha who served in the Royal Army of the Golden Empire.
Trapp enlisted in the Royal Army in 146 ABY. He had intended to join an armored division, but was channeled into the infantry instead. He excelled there, serving during the Nightmare War in the Defense of Daispin—where he earned the Medal of Fortitude—and the assault on Awpierh.
When Trapp was promoted to corporal, he transferred into the Assault Commandos. There he continued small arms training to become a weapons specialist in a unit already known for its expertise with weapons. Trapp and his unit took part in the Battle of Renthiv in 155 ABY. Afterwards, due to his blaster skill, Royal Executor Breek Zagrev tasked Trapp to train her apprentice, Jinyx Windrunner, in basic blaster technique. Trapp and Jinyx went together to Daispin while Jinyx was receiving training from Vem.
