"You mean," demanded the Gogean, "you _comprehend_ this mechanism?" Kang nodded. "But then no one need enter Khundru!" "Unfortunately, someone must. There is no way to rupture an entropic force barrier from without. If your divisions are to storm Khundru, the wall must be broken from the control room inside that city." * * * * * Gary drew a deep breath. "O.Q. We're elected. Lark ... Hugh ... Flick...." "A moment, Gary," interrupted Lark. "Just how are we to effect entry into Khundru? Will there be questions to ask or answer?" Tsalnor puzzled briefly. "It would be best," he decided, "to pass yourselves off as common serfs. We shall teach you the Magogean language and acquaint you with its customs. But it would take too long a training to enable you to pass yourselves as members uff the ruling class. There are but two divisions uff Magogeans. The common people, serfs who are little more than feudal slaves; and the kraedars, or overlords--" "That's what Borisu called himself," remembered Gary. "Kraedar." "The kraedars are the military and ruling class. You would never be able to pass yourself off successfully as one uff these. Therefore it were wiser to allow yourselves to be taken into the city as workers. This may entail some hardships, but you will be inside where you want to be. And once there, your own ingenuity can devise ways and means uff doing that which is needful." "I thought," nodded Kang, "the situation would be something like that. In that case, Gary, you must change your plans. Nothing would arouse Magogean suspicion quicker than to have five strong, strapping, young strangers seek entry to their capital city ... particularly on the heels of the report Borisu may even now be submitting to his peers." "But who, then--?" questioned Gary. "Why not," suggested Kang quietly, "just my daughter and myself? We understand the operation of the force-shield. Of the two of us, surely _one_ can find some way to break the Magogean barrier for a short time." Gary said stubbornly, "The idea is a good one, Dr. Kang. But two is not enough. Let it be the _three_ of us." "The _four_ of us," broke in Lark O'Day. "If Penny's going, I want to be in on this shindig, too." "Why not," suggested Nora Powell, "count me in? With two women out of five, certainly we would seem an innocuous little band. A family circle, so to speak, with Dr. Kang as the parent, Penny and I his married daughters--" Kang said dubiously, "I don't know. There is too much difference in the pigmentation of our skins for us to be taken as a family unit. True, my daughter's flesh is little more golden than yours, Miss Powell--" Tsalnor dismissed the objection with a short laugh.
