For those of you who helped me last time. My group loved the adventure.
My new idea for a adventure also revolves around necrons and a C'tan, but this time instead of it being a shard its a weak but complete C'Tan. Here is the mission briefing i wrote up.
"A Necron Tomb had awakened on mars. Almost immediately the necrons start reacting in a strange behavior pattern not yet seen. The necrons spill from the tomb but only far enough to form a 10 man deep parameter around the tomb before the rest receded in to the tomb. Shortly afterwards towers rise from the tomb complex, one of these shot down one of our expeditionary craft.
3 days later a signal for help came over the vox network. The problem was is that this particular band of vox was reserved for the Emperor himself. The call for help said several necrons had invaded Noctis Labyrinth and that it needed immediate extraction.
The mission is to delve deep into the labyrinths of Adeptus Mechanicus and push the necrons back so they do not conquer mars and steal our most important forge world, not to mention a stepping stone to Terra. Also if possible capture a necron for study"
What will be explained to the team as they go through the labyrinths is that after the emperors battle with Mag'ladroth. (A.K.A the void dragon) The C'Tan swore undying fealty to the Emperor. Due to its injuries the C'Tan required rest, and so went to sleep inside of mar's ancient magma tubes. The Emperor believed the C'tan would betray the Empire and so attached a warp powered device to the C'Tan that would brainwash the C'Tan into being singularly loyal to the empire, while teaching it all the views that he espoused. Unfortunately the device malfunctioned and while still loyal to the empire believes the emperor is a god. It will be explained through various ancient holo-tapes with most of them made by the Emperor of Man himself.
Mag'ladroth was awakening due to it sensing the weakening of the Golden Throne. Ironically the waking of the C'Tan awakened the Necrons that were on mars. The necrons have a empty Tessaract Labyrinth device to trap the C'Tan. The team is to defeat the necrons taking possession of the Tessaract. The end decision is ether a battle until they can trap it themselves in the Tessaract, or to let the C'Tan leave for Terra and renew its fealty oath to the Emperor.
So is this too much heresy not not enough or not interesting enough? Just need some input from those that know more lore then I. I would appreciate any constructive criticism.
