第二基地
Channis leads the search to Tazenda, which is a plausible place for the Second Foundation to be located. Channis and Pritcher visit a world controlled by Tazenda, Rossem, where the local elders, members of the Second Foundation, have been expecting them. When they return to their ship, Pritcher also comes to the conclusion that Channis is a member of the Second Foundation, and draws his atomic blaster on him, saying that the Mule would shortly be coming (both men had found the hyper tracer). Channis, however, uses his mental powers to convince Pritcher that he is not a member of the Second Foundation and that he (Pritcher) was being manipulated into killing him by the Second Foundation, who Channis says had planted the hyper tracer. Pritcher, convinced, decides to hand his blaster over to Channis.
