"The younger Kro-lu favor the plan," replied the warrior, "since they believe they will thus become Galus immediately. They hope to span the long years of change through which they must pass in the ordinary course of events and at a single stride become Galus. We of the older Kro-lu tell them that though they occupy the land of the Galu and wear the skins and ornaments of the golden people, still they will not be Galus till the time arrives that they are ripe to rise. We also tell them that even then they will never become a true Galu race, since there will still be those among them who can never rise. It is all right to raid the Galu country occasionally for plunder, as our people do; but to attempt to conquer it and hold it is madness. For my part, I have been content to wait until the call came to me. I feel that it cannot now be long." "What is your name?" asked Ajor. "Chal-az," replied the man. "You are chief of the Kro-lu?" Ajor continued. "No, it is Al-tan who is chief of the Kro-lu of the east," answered Chal-az. "And he is against this plan to invade my father's country?" "Unfortunately he is rather in favor of it," replied the man, "since he has about come to the conclusion that he is batu. He has been chief ever since, before I came up from the Band-lu, and I can see no change in him in all those years. In fact, he still appears to be more Band-lu than Kro-lu. However, he is a good chief and a mighty warrior, and if Du-seen persuades him to his cause, the Galus may find themselves under a Kro-lu chieftain before long--Du-seen as well as the others, for Al-tan would never consent to occupy a subordinate position, and once he plants a victorious foot in Galu, he will not withdraw it without a struggle." I asked them what batu meant, as I had not before heard the word. Literally translated, it is equivalent to through, finished, done-for, as applied to an individual's evolutionary progress in Caspak, and with this information was developed the interesting fact that not every individual is capable of rising through every stage to that of Galu. Some never progress beyond the Alu stage; others stop as Bo-lu, as Sto-lu, as Band-lu or as Kro-lu. The Ho-lu of the first generation may rise to become Alus; the Alus of the second generation may become Bo-lu, while it requires three generations of Bo-lu to become Band-lu, and so on until Kro-lu's parent on one side must be of the sixth generation.
