I do not know how writing this will help us in our cause, but Lord Inquisitor says it will boost morale and stop the spreading of heretical thoughts through the minds of other acolytes. The Inquisitor knows best, I guess.
To be honest it's not all bad in here. Sure we've got our share of trouble: sometimes the munitions are hard to come by, sometimes there are problems with communications, and it would be nice to have a chance to work on our weaponry using the spare parts, but the Mechanicus lady wouldn't take kindly to that it seams. But all that is part of the routine and can be easily ignored. What matters most is that when I am out on the ground with my fellow warriors I feel alive, I feel like we are making a difference if only a little, but still. So, I will continue to serve The Throne until my days are numbered, and then someone else will pick up my trusty sword and gun to carry on the fight for The Emperor and glory of Mankind.
