Molossus

Molossus is an Imperial agri-world of the Punic Systems, located in Sector Occident Prime in the Phoenicia Sub-Sector. This planet is the Astra Militarum Homeworld of the Molossian Dog Regiments, an unusual cavalry force whose troopers are mounted upon giant hounds native to the planet. Given their resemblance to ancient Terran breeds it seems probable that the various strains of Molossian Hound are a genetic experiment gone feral rather than a naturally evolved species. They are the riding and draft animal of choice on their homeworld and as war mounts have the advantage of a massive intimidation factor.

History
Ten thousand years ago, at the time of the Great Crusade, Molossus was a savage feral world where warlord fought warlord with dog mounted cavalry. By the 41st Millennium however Molossus is a civilized agri-world; pious and productive. There are the usual aristocratic factionalism and intrigue and occasional succession crises but by and large Molossus is peaceful. However the space beyond her atmosphere most certainly is not. Molossus has been raising mounted regiments for the Imperium as part of their tithe since the planet was conquered by Derik Loculus. There are presently hundreds of Molossian regiments serving in as many war zones but a brigade of four regiments under Brigadier Maximiliano is stationed on Zhogun, the sector capital, as a rapid reaction force for the more primitive sector worlds or as scouts in support of more conventional regiments.

Phoenician Sub-Sector
The Phoenician Sub-Sector forms a complete contrast to its neighboring sub-sector to the north. It has planets rich in promethium and other valuable minerals, flourishing hive-worlds, industrial worlds and agri-worlds enough to keep them all fed and supply luxury crops for export as well. Purpura Mundi The sub-Sector capital is a major emporia of the Sector. If you can't find it in the markets of Purpura Mundi it doesn't exist. Phoenix is an important sources of promethium and metals and Flammifer an industrial center. The Punic Systems are a chain of mid-range stars illuminating both hive and agri-worlds, including Molossus.
