Iocanthos is a lawless Imperial Agri-World in the Calixis Sector's Golgenna Reach Sub-sector in the Segmentum Obscurus. Iocanthos is dominated by warlords and their huge armies, which clash across its jungles, forests and plains. The planet’s importance in the Calixis Sector is defined by the fact that it is one of the few places in the Imperium where the Ghostfire flower can grow. Ghostfire pollen can be refined into the combat drugs used extensively in the Penal Legions of the Imperial Guard.
