Nerri was the older brother of Chiana, an outcast Nebari, and a leader of the Nebari Resistance. In their younger years, Nerri and his sister chose to be different by leaving their homeworld of Nebari Prime and seeing the galaxy. They were surprised to find that their planet's government, the Establishment was willing to give them transport off of the planet along with a free "medical examination". In fact, the Establishment had infected them with a contagion that would be spread throughout the galaxy through sexual contact.
