Calixis Sector - Iocanthos: Iocanthos is a lawless Imperial Agri-world in the Calixis Sector's Golgenna Reach sub-sector. Iocanthos is dominated by Human 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 Astra Militarum.Iocanthos' warlords (usually styling themselves "vai" or tribal prince) battle constantly for control of the Ghostfire harvest. The Ghostfire crop cannot be cultivated normally and so once a patch of it is harvested another one must be found. The warlords' armies are therefore constantly on the move, travelling in enormous hordes across Iocanthos' main continent and clashing violently wherever they meet. Iocanthos' wide plains, dense, dark forests and forbidding mountain passes are studded with old battlefields where burned-out vehicles and age-bleached skeletons abound.Every five standard years, a taskforce of Administratum officials descends onto Iocanthus to gather the planet's Ghostfire tithe. The warlords exchange their harvests of Ghostfire pollen with the Administratum in exchange for weapons, vehicles, fuel, clean water and other essentials. The warlord who hands over the most Ghostfire pollen is considered the planetary governor and claims the lion's share of support from the Imperium and the title vervai (literally "prince of princes" or "king"). The title brings with it immense prestige and confirms the warlord's position as the most dangerous and skilled on Iocanthos.The current vervai is "King" Skull, a terrifying warrior at the head of an enormous and supposedly invincible army of madmen and killers. The warlords of Iocanthus are also required to hand over their psykers as well as the Ghostfire harvest, but these are taken from them not by the Administratum but by nameless grey-uniformed men who herd the psykers onto their sleek Black Ship and take their leave.The Administratum fully accepts the situation on Iocanthos. The Ghostfire pollen is harvested very efficiently because so many warlords' armies battle to find every last blossom. Were the Administratum to take over Iocanthus themselves the planet would first have to be conquered by the Astra Militarum at enormous expense and the Administratum themselves would be hard-pressed to match the vigour with which Iocanthos' warlords hunt down every Ghostfire flower. They therefore leave the warlords to do the hard work, safe in the knowledge that none of them can rebel against Imperial authority lest their supplies of guns and fuel be cut off.Iocanthos was taken by General (Saint) Drusus' 2nd Army Group during the Angevin Crusade that spread throughout the sector. As the planet lacked any significant technology, Drusus' forces defeated the indigenous people, known as the Ashleen, in a single solar week of bloody fighting. Drusus later remarked in his memoirs that the only memorable aspect of the planet was the vast fields of wild flowers which resembled "Shimmering fields of rippling explosions, caught at that fleeting moment between beauty and destruction." As ever, the general was perceptive as the Ghostfire would become central to the world's future.In times past, Iocanthos served as a penal dumping ground for undesirables that the Scintillan authorities for various reasons didn't wish to execute or expatriate further afield. Such exiles were given minimal supplies and allowed to thrive or falter without further interference. The current population is largely a mixture of their descendants and the native Ashleen.
