Tesrn Edap was a Xexto Jedi Padawan from Troiken. His Master, Pyrn Werd, taught him to wield two lightsabers in the Jar'Kai style. He was considered quite formidable for a Padawan. He fought in the Battle of Leziquk alongside his Master. The Republic Naval fleet came under attack in orbit. Tsern managed to reach the planet's atmosphere, and battled in the skies. However, his Eta-2 interceptor was critically damaged by the attacking droids. The Padawan jumped out, used the Force to soften his landing, and cut through the waves of war machines. Tesrn fought well, and even managed to disable a few tanks, but he was soon killed.
