Former capital world of the Thracian Sector, Odessos Prime was never a shining beacon of imperial virtue for during the great crusades was an independent realm called the Oddryssian Kingdom that fought fiercely to deny the imperial truth. Eventually brought to compliance, the sector stayed out of the Horus Heresy and existed in relatively stable peace, rather unusual for an imperial sector on the fringe of imperial space.
In mid M39 a catastrophic accident occurred, the first moon exploded over the capital shattering the sectorial fleet that just happened to be at anchorage in orbit and of course decimated the planet beneath. Weakened the entire sector came under prey from Xenos incursions such as Ork Waaaaaghs! and Eldar pirates.
Upon Odessos Prime amidst all the destruction hive Tertius declared independence from the imperium and launched forbidden atomics assumed supplied by rogue elements of the mechanicus and decimated swathes of the two remaining hives Primus and Secundus before defensive measures could be taken.
Now after 500 years the Imperium has launched a reclamation campaign into the sector with seemingly random goals and a fierce intensity. One of the primary goals is the reconquest of Odessos Prime for which the situation has since deteriorated upon the planet.
Two factions currently vie for dominance upon the surface, the newly revealed forces of Chaos that was behind the rebellion of Hive Tertius and The Imperial loyalists of Hive Primus that are still attempting to maintain order.
History : The Last 500 Years
500 years ago – The Calamity: The event that rendered the entire sector defenceless. The entire sectorial fleet had gathered at the orbital shipyards about to embark on an important endeavour now forgotten, and though security was tight no one could of anticipated the primary moon exploding. The explosion devastated the fleet and shipyards, the resultant debris rained destruction upon the world devastating swathes of the land. As if this was not enough Hive Tertius declared war on the other two hives and levelled Hive Secundus with forbidden Atomic weaponry.
460 years ago – Revelation: Hive Tertius finally reveals its true colours as increasing waves of chaos warbands arrive and daemons are summoned into service.
500 – 20 years ago – The Years of Terror: 480 years pass with a grinding stalemate with the loyalist forces defending the remnants of Hive Secundus pushed back and now defending the besieged Hive Primaris. A few isolated mechanicus outposts hidden from the populace reveal themselves during this time and lend aid to the populace.
20 years ago – The Krieg – 3 lone troop transports exit the warp above planet and immediately descend to hive primaris’s starport the defenders unsure about the new arrivals are relieved when Death Korps of Krieg emerge specifically the 135th Assault Brigade with the 113th Death Rider Brigade attached. These forces save the day on more than one occasion but are unable to tip the balance in the imperiums favour.
15 years ago – Zylek : The imperial forces holding well due to the kriegs expertise in siege warfare are outmanoeuvred when chaos forces use sorcery to create warp portals teleporting them into there midsts, the Krieg General is cut down in a challenge by “Zylek Architect of Despair” a dark apostle of the black legion believed to of been behind the initial corruption. Before the krieg could get revenge Zylek escaped through the warp. Field Marshal Kruger of the 113th Death Riders takes overall command and is renowned for his stubbornness.
Now – Salvation: The imperial defences have collapsed and the chaos host march on Hive Primarus. The imperial forces see all hope lost and Governor Garrick Al’Vorn considers overloading the hives generators to cause a cataclysmic explosion. All hope however is not lost for above the turbulent stormy skies an imperial crusade fleet has entered orbit hoping to liberate the defenders below.
What happens next? We shall soon find out…..
