Hello. What you have just read, assuming you've read them in the right order, is the background fluff for the Autumn Conclave.
There is more to come of course - more hints as to the Corporal's true nature in the coming weeks.
Feel free to call me on any errors.
One thing that comes to mind is the Carthaxian Conclave thread initially lists "Pillarus Prime" as the home of the Carthax sector Conclave. I'm not sure whether that's supposed to have been retconned by "Tigguo Cobauc", or whether that's simply meant to be a less important Inquisitorial fortress.
You may also question my writing, if such a thing takes your fancy.
But if you do, cut me some slack - it turns out it's actually bloody difficult trying to write a believable saint, because a lot of the time it comes down to "Why weren't they declared a psyker/mutant/etc and shot on sight?". Particularly when you need actually need to leave that doubt in there, so players have got something to argue about on the day.
