Irukan

Irukan is the Kig-Yar name of a Sangheili grain normally grown by the Kig-Yar. Jul 'Mdama requested irukan after he informed Irena Magnusson that human grain didn't agree with his digestion. The Irukan grown later on Trevelyan were used to test genetic modifications, making the grain indigestable to Sangheili. The Irukan grown would have been used to starve Sanghelios' population if ONI's plan of internal dissent failed. Dr. Magnusson noted that the genetically modified irukan would completely overwhelm the native strain in less than three years.
