Hey!
Whats up, how is everybody?
So I had a quick question for you guys, more versed in 40k fluff then I. I have been running another adventure (not Idyll heresies, even though that's still going rather well), which has a bunch of Acolytes intruding a Rogue Trader's mining colony to recover a rogue psyker who has accidently teleported himself there, only to be captured by a cult who has been developing secretly for a while now.
As you can see, truth be told, the Mining part of the mission was so irrelevant, I did not think to fluff it. When asked about what they were mining that was so important (to justify the rogue trader buying the land, and nullifying any semblance of authority they had so that they don't walk in guns blazing killing everything and everybody (the tech-priest is rather zealous)).
Now, they took a lot of hints I have given and expanded on them to make up quite a nice story. However, when they had asked about what exactly was being mined, I simply threw out "crystals" because well, I didn't think gold was that rare or worthwhile anymore in the 40k, as everything is made out of gold. Well, granted everything expensive, but still, not expensive enough to justify a rogue trader taking over.
Now the group has a lot of theories of what could be causing craziness in the colony: mutations, warp infection, crazy cult, and last but not least... the crystals themselves. The tech-priest has seemingly figured out what these crystals are, and believes THEY are causing the mutations.
Now i have looked up as much Info on crystals as I could possibly find, and I still couldn't find any hints of crystals causing mutation trough exposure. Perhaps he thinks its Kryptonite or something? I am not quite sure!
So It seems the guy is better versed in the lore then I am, and I may have accidentally put my foot in my mouth by throwing out "crystals" as the "thing they were mining".
Any ideas what cannon crystals cause mutations that could possibly be down there, or do I have free reign to make stuff up myself, based on the Tech's priest assumption, and develop it as another red-herring?
