The Destructors were a civilization from another galaxy in Keshiri legend. They came from another galaxy to the galaxy every few eons to eliminate civilization and return things to the primitive stage. It has been believed the Destructors were myths until 13 ABY when evidence was found on the world Kesh that they came to the galaxy before, and according to Chiss recirds, the Chiss Empire had a war with the Destructors in 1,000,000,000 BBY which was known as the Yuuzhan/Destructor-Chiss War, which led to the Empire's formation.
