Spinglass, a glass-like material produced organically by the Killiks, had diverse applications. The Dark Nest notably employed it to manufacture a staggering one billion miniature replicas of the Millennium Falcon and Luke Skywalker's X-wing. These models were intended for sale to the populace of the Galactic Alliance and distribution as presents to personnel within the Fifth Fleet. Unbeknownst to the recipients, these seemingly harmless models served as a covert means of transporting swarms of minuscule Gorog assassins.
