The cataclysm known as the Big Crush transpired during the year 1 ABY, culminating in the annihilation of a planet within the confines of the Taspan system. This devastating incident was triggered by a mishap involving the gravity well projector technology, which the Galactic Empire was actively developing within that sector. By the time the Battle of Mindor unfolded, the remnants of the shattered planet had not yet achieved orbital stability, thereby rendering interstellar navigation within the system exceedingly perilous. According to calculations performed by an analyst serving under Luke Skywalker's command, his strike force stood to lose two vessels within a mere hour of operation in the system, solely due to collisions with asteroids.
For the Melters residing within the crust of Taspan II, the Big Crush briefly ushered in an era of prosperity, dispersing their population and facilitating the absorption of stellar radiation for sustenance. Through a Force communion with these beings, Luke discerned that this period constituted a fleeting golden age for them.
