It was a source of human resources for the Imperium.
The planet was a river world featuring vast plains of fertile land and a healthy hydrological cycle. Though it was dotted with many settlements, by far the largest was Poritrin City, which at its height was a hub of culture and luxury for free humans during the Butlerian Jihad.
Poritrin had one small moon.
The early history of Poritrin was dominated by the Bludd family, who governed the planet before and during the Butlerian Jihad. Poritrin was a member of the League of Nobles, and after Sajak Bludd's rule, a staunch supporter of slavery. Indeed, Poritrin's powerful agricultural and light industrial sectors were highly dependent on its large number of Zensunni and Zenshiite slaves.
During the unrest of the Butlerian Jihad the planet was famous as the cradle of scientific celebrity Tio Holtzman, the inventor of the Scrambler web. During that time, the planet experienced an uprising instigated by Bel Moulay, a Zenshiite slave sage. However the uprising was violently suppressed by government forces. Moulay was ceremonially tortured and executed in public in place of the uprisers.
About 20 years later, Poritrin was used as a 'bait' by the Jihadi intelligence, which lured a machine attack against the planet. According to the plan however, the planet was 'defended' by a large number of decoy ships that confused the machines and were driven off by real fighters. The mastermind of the plan was Vorian Atreides, while the construction was overseen by Holtzman.
The second uprising culminated in a massive explosion that devastated Poritrin City, and greatly reduced the world's influence in galactic politics. Unlike his predecessor, Porce Bludd was a philanthropist and participated in building New Starda.
