The Lani People by Jesse F. Bone

Kennon was morally certain that the Lani were of human stock. Evolved, of course. Mutated. Genetic strangers to the rest of humanity. But human. The spaceship and the redes proved it as far as he was concerned. But moral certainty and legal certainty were two different things. What he believed might be good enough to hold up in a Brotherhood court, but he doubted it. Ulf and Lyssa might be the founders of the Lani race, but they had come to Kardon nearly four thousand years ago and no records existed to prove that the Lani weren't here before they came. Redes passed by word of mouth through hundreds of generations were not evidence. Even the spaceship wasn't the absolute proof that would be needed to overturn the earlier legal decision. Other and better proof was needed -- something that would stand up in any court in the Brotherhood. He hoped the spaceship would hold that proof.

But Kennon's eagerness to find out what was inside the ancient spacer was tempered by hard practicality. Too much depended on what he might find inside that hull. Every step of the work must be documented beyond any refutation. Some method of establishing date, time, and location had to be prepared. There must be a record of every action. And that would require equipment and planning. There must be no mistake that could be twisted by the skillful counsel that Alexander undoubtedly retained.
