The sister ship was exploring a solar system when the K'zata emerged from hyperspace. The K'zata incorrectly identified the sister ship as the Christa, and not knowing that this vessel was manned by a full Lumanian crew, they attemped to seize it. The sister ship opened fire on the K'zata and a battle ensued. The battle ended when the K'zata was completely destroyed. However, the sister ship was disabled and damaged beyond repair. The K'zata was able to launch an escape pod as blew apart it and it was now heading toward the damaged sister ship. The Lumanians evacuated their ship and set her to self-destruct, a gift from the Lumanians to the forthcoming Spung. An automated distress signal was sent and the true Christa responded.
