Having recently come into possession of a priceless tome of blasphemous knowledge pertaining to Radical Inquisitors, I found myself very intrigued by the mention of an Inquisition War. Personally, I think it would make a wonderful background for a campaign, Radical or not, as it allows for the widest range of missions imaginable and could pit the Acolytes against the most memorable foes in the Calixis Sector - Inquisitors.
Also, with the Inquisition busy, Chaos and Xenos might have a field day.
However, I cannot find a good reason why a war should break out. I mean, what could be strong enough to override caution and common sense in the face of such things as the Tyrant Star? Plus, I might lack a bit of background as I have not read the adventure modules which nonetheless seem to contain quite a bit of additional information on the sector and its dark legacies.
Now, I wonder...could some of you be helpful and give me a few incidents or occurences that could start a full-blown Inquisition War. A few suggestions would be enough to make my day
Conspiracy, anyone?
