Haddrack is a death world and minor forge world on the edge of the Drusus Marches of the Calixis Sector, a world where vast sulphurous seas have poisoned the land and acid storms driven by hurricane-force winds can strip flesh from bone in moments. Yet even on Haddrack life endures. Here the militant Adeptus Mechanicus of the Sollex sect are based, drawn to the world by its unique crystalline deposits, their black basalt fortress stabs up through to burning skies like a clawed hand.
Haddrack's southern continents are home to a Kasballican princess, Princess Ignetta, who has become invested in the current holy war upon Protasia. Adeptus Arbites Detectives are carefully infiltrating the Governor's court and the Departmento Munitorum to try and track Kasballica efforts to manipulate the Imperial Guard tithe for the nearby warzone. Princess Ignetta has involved herself on two fronts---using none-too-subtle bribery and coercion on the planetary authorities so that the human tithe falls heavily on the planet's two major northern continents, while her own main power base across the three southern continents remains strong, and ensuring that a number of Kasballica agents personally loyal to her are shoehorned into command positions in the Guard tithe. Ambitious and optimistic, she is looking forward to the day when the Haddracki regiments take Protasia and claim it, and the new settlers will be led by her own catspaws and established as a Kasballica fief subject to her control. The Arbites have not yet tarnished that optimism by launching into righteous prosecution against such a shameless crime against the Adeptus, but the case against her is almost complete and the day of reckoning is not far off.
