Although I have not heard of you or the group you represent specifically, it is a joy to hear from the Golden Chrysanthemums again. Although I was retired at the time, I heard of some of the effort you put in on our side of the first Tau War. The fact you are willing to assist in this grander one is also good news.
You are now registered to carry Military Goods, and any other goods out to the Taus. "Pirate Trains" and other similar ships, your papers and your transponders are legal in the hands of those we trust, and you will also find that you may hold up to five units of Cardamine within Bretonian law (specifically put in place for those who require it to survive). As long as you stay within the rest of our laws, you will have no problems here.
When you are disrupting Gallic trade in the Taus, some goods may be of use to our nation and the war effort - if you can spare them, do bring them on the return journey. You may also wish to contact Her Majesty's Most Diligent Interdiction Wing - our Privateers - out in the Taus, who specialise in doing much the same.
