This will be my first 'original' Deathwatch game, as in, I'm not running it out of a book.
Here's the fluff part I got:
------------------------------------------------
The Planet of Jamash:
The planet of Jamash lies to the galactic north of Halex Anomaly in the Jericho Reach. The planet was discovered during the Emperor’s Great Crusade. The planet was pristine and welcoming to life, yet devoid of sentient life. Colonization was started immediately and considering the safety of the quadrant, the planet was also elected for many advanced structure to be built, as it would most likely become the capital world of the sector. The Mechanicum built many facilities and even installed refueling and maintenance station for the Titan Legions.
But then the Heresy started. As more and more forces were drawn out of the Reach, chaos and strife broke out over the planet. Forces loyal to the Warmaster infiltrated the rank of the guard stationed on the planet and through deceit and lies, guided their forces in a battle against the Mechanicum… accusing them of Heresy. The battle was brutal and complicated – as force loyal to the Emperor within the Guard and force loyal to the Warmaster within the Mechanicum both tried to change the tide… ultimately the battle went on for long after the Warmaster fell, and only stopped because without fueling from the Imperium, supply ran out.
The damage had been done however. The Mechanicum was broken, all the tech-priest dead or in hidden away in slumber. Most of their facilities had been destroyed or abandoned. The Imperial Guard realizing too late they had traitors in their mist, still tried to purge them, turning against each other. But without the support of the Mechanicum, their ammo ran out, their broken gear could not be repaired and the war on Jamash did not end with the bang, but sputtered away into darkness. The Imperium itself was too busy dealing with its own problem, and Jamash was forgotten.
The once pristine planet was now a war thorn battlefield. Before the war, colonization and industrialization had already done great damage, but the war finished it off. The remaining humans scattered across the land, living off what meager resource they could. They split into tribes and clans, fighting for territory and food. Over time, the reason for the conflict became stories and legend, fire side tales. The Imperium Creed changed or even was forgotten by some clans. The Age of Shadow came over the Reach, but was barely noticed for the tribes of Jamash.
At the onset of the Achilus Crusade, a Rogue Trader by the name of Zudo Edgetsvi was acting as a vanguard for the fleet, his task to re-discover world and flag them for conquest, re-colonization or assault, as the case maybe. He encountered Jamash and could see that the planet had once been a bastion of the Empire, but would now be considered a feudal world – technology and culturally – with the exception of some still working piece of Imperial technology that were considered as relic and magic items.
This world would not only be easy to colonized, but could also be used to recruit soldiers for the crusade - man who were already war hardened. He sent down his Missionary of the Missionarus Galaxia to ferret out which tribe was closest to the Imperium Creed and side with them.
All of a sudden one of the tribe was backed by troops from the Rogue Trader as well as functioning weapons and training on how to properly use and maintain them, it quickly rose and built and empire on the planet, re-learning the Imperial Creed and pledging itself to the God Emperor. Zudo then went on his way, knowing the Crusade wouldn’t be far behind and would have a perfect re-supply point waiting for them.
Zeroth, the Accursed Seer
Zeroth was a Librarian of the Night Lords during the Horus Heresy. Following the fall of the Warmaster and the splitting the Legions into Warband, Zeroth embraced the worship of Tzeentch. His great power of foresight and clairvoyance allowed him to lead many successful raids from the Eye of Terror in the 10,000 years since his betrayal, and successful raids earned him respect and leadership of his own Warband.
Following portents and signs, he guided his warband through the Hadex Anomaly to the planet of Jamash, where his vision told him great weapons lay dormant and those weapons would be of great help in the coming wars with the servants of the corpse-emperor.
Zeroth and his warband landed on Jamash shortly before Zudo came, following his visions, they lay low, approaching the savage tribes of the north, the descended of the traitors that spurred the war, and mercilessly took over. They then used them as man power to try and find the weapon cache… and they did. Hidden within a mountainside, they found one of the Titan’s Legion maintenance installations… with 3 abandoned Titans within. The mountainside was believed to be haunted by the many tribes (in no small part due to the still active security system of the installation).
Zeroth re-established his base of command within the mountains, and set up his Obliterators to work on the Titans… while Zudo was conquering the planet, Zeroth was in hiding. But progress is slow… the Obliterators are not familiar with the working of Titans and the 10,000 years of neglect has not help the factory any.
Zeroth’s plan is pretty simple. Once the Titan are operational, his fleet will come of their hiding spot in the warp and the Titans will be take off the planet. Zeroth brought a Magna-Melta Bomb, which is secured inside the mountain base… once the Titans are off, the planet will be destroyed.
3 Titans brought to the Cellebos Warzone are certain to change the tide of battle and earned Zeroth great glory in the eyes of the Legions and the Chaos Gods.
The Deathwatch
Zeroth’s plans would have more than likely gone off unnoticed and been carried to fruitition without an itch if it’d been for mistake committed by one of the tribal working under the Obliterators. With the mistaken flip of a switch, a communicator array was re-activated and sent out the last call for help of the Mechanicum – 10,000 years late. The power (and the tribal) was quickly terminated… but not before it could reach a Watch Station, which recorded the message. This record eventually found its way to Inquisitor Vils Andarion.
Andarion is wary. Records do not show Mechanicum presence on Jamash (those are long lost to the flow of times), so getting a 10,000 years old message for help from a planet that should not have said faction present is… troubling. He is however, taking this seriously and he intends to go to Jamash and find out if there’s anything to it. He understands the locals are freshly returned to the Imperium, and doesn’t want to have to worry himself with politics with a bunch of freshly converted feudal savage… a show of strength is required. On top of his retinues and some Inquisitorial Stormtroopers, he will bring a Kill-Team with him. Certainly the Emperor’s Angel of Death mere presence will make those feudal men more than willing to cooperate. And if there is indeed something to this message, than a Kill-Team may not be to much firepower.
Zeroth of course, knows of their coming.
------------------------------------------
Gameplay Consideration:
Zeroth will be a Master level opponent (Always had a weak spot for Chaos Sorcerer HQ). They'll be plenty of elite opponents I'll have to make templates for (Berzekers, plague marines, Obliterators) and plenty of hordes as well (Feudal/Tribal Cultists).
The story itself will start as political game of 'Escort the Inquisitor'... weirds things will start happening, murders and so forth. The players will have to do some investigating and deals with the feudal. Eventually they'll either find out that there is a chaos presence on the planet or Zeroth will strike. At this point all hell breaks loses and it will be a war between the chaos warband and its cultists and the deathwatch, inquisitional force and the the feudal people of Jamash. The Imperial Force outnumber the Chaos Force, but the Chaos Warband is much larger than the Kill-Team, which greatly even the odds. Also, the Deathwatch came here on 1 ship... Zeroth's Warband count several ship in its fleet, so they have 'space superiority'.
This should all go on over several game sessions, I of course need to hammer out details, interesting plot points, npcs and so forth.
The climax of the story should come with the Kill-Team assaulting the installation as the titans are being brought out. A mad battle between all involved to the rythm of the ticking of the Magna-Melta Bomb's timer going down. While I like to keep a possibility for the players to have a perfect victory (stop the bomb, kill Zeroth, prevent the Titans from falling into Chaos hands), from a story point of view it would be more interesting if they had a partial victory (i.e. Zeroth escapes and/or the titans fall into chaos hands anyway... allowing for a part 2).
