Preem Palver arranged for Kalgan to declare war on the Foundation through his agent Lady Callia, who was mentally manipulating Kalgan's ruler, Lord Stettin. Kalgan lost the war, and so restored the Foundation's confidence in its purpose. In his guise as a farmer/trader, he also negotiated to supply the Foundation with needed supplies at the close of the war, at which time he passed on Arkady's message. Dr. Darell, in the meantime, had pioneered an electronic "Mind Static" device that emitted a strong mental field using the brain's radio-wave composition. Successfully finding an undercover agent of the Second Foundation among them, Dr. Darell and his associates interrogate him and find the Second Foundation on Terminus. The Second Foundation is then "eradicated" by the First Foundation, which now believes itself to be the only Foundation left, and can establish the second galactic empire without interference.
