I have run a few pre-fab games of dark heresy and now I am looking to write my own adventure from scratch and I am looking for some constructive feed back on my ideas
The adventure begind with the acolyte's traveling to investigate a mysterious space station over a medieval world when thier ship is shot down from the surface of the planet and they are forced to crash land
once on the planet they will have to investigate the origin of the attack make repairs to thier ship find supplys to survive make contact with the local civilisation and endure environmental hazards
eventualy they will discover an impereal castle town where the locals are defending against an ork warlord and the acolyte's can aid the defenders if and when they achieve victory over the orks further investigation will reveal something the locals refer to as the "magic city" which will be strongly hinted to be an advanced civilisation and possably the source of the attack
then the acolyte's will have to travel through ork territory/general dinosaur infested badlands to reach the "magick city" which turns out to be a heretek conclave they can either pursuade the ork to turn thier agression towards the "magick city" but then the orks would be able to loot the heretek technology or they could make a deal to help the heretek's in exchange for passage off world wether the players defeat the heretek's or cooperate with them they can either salvage parts to repair thier ship or be granted passage to the space station
once on the station the players will find it mostly deserted deralict and in a general state of desrepair there they will either force thier way past guards or be granted an audience with the heretek leader inquisitor Cyrrik Scayl who will explain to the players that he and his deciples are investigating the technology on an ancient alien civilisation and that they cannot let thier research fall into the hands of the adeptus mechanicus just to be declared tech heresy and destroyed if the players attack Cyrrik he is easily defeated and turns out to be a replica his voice will ring out over the stations communication systems and tell the acolyte's that the station is fall out of orbit and detonate a powerfull warhead erasing any evidence that he has left behind and that they have a short amount of time to escape alive
a player will have the option of remaining behind and disarming the warhead thus saving the medival civilisation but dooming himself to die upon reentry
so that's it the players will have some motivation to persue Cyrrik and that will set up further adventures and possably a plot arc
