Benny leads an expedition to find out more information about the long-extinct Avanonions. The planet is subject to violent sandstorms. Benny and Corin have developed a taste for the eggs of the native chicken-like species, though Mabe only eats rations. Sometimes the animals attack when their eggs are taken. The trio uncover a tomb which contains mummified egg shells and find a cartouche with writing. Back at camp, during a ferocious sandstorm, Mabe analyses the egg shells' DNA while Corin works on the writing.
