Planet: name unspecified. A humanoid race, distinguished in appearance by lightly upswept eyebrows and a rough-textured membrane that covers the top of the ear and melds flush to the head. Some can telepathically retrieve the hidden memories of other humanoids after years of specialized and intensive training. Using this skill, the people have embarked in amassing a library of history that is researched by retrieving personal memories of many worlds' individuals. Fellow telepaths can monitor each other, and often do out of fear of what has been termed "telepathic memory intrusion," considered to be akin to rape in their culture.
