The Coreseeker Missile is a weapon of Nall design. Its sole purpose is to be fired into a planet, penetrating to the core where it delivers its explosive payload. The resulting detonation rips the world apart from within, leaving nothing but a field of debris in its place. This was the fate of Youngster, now known as Ungstir. Despite its ghastly effects, the Nall have no moral conflicts against deploying it when they need to.
