I think we should leave the Druchii and HE to their own devices. There is an age-old motto that I think should be applied to this campaign - "Keep it Simple, Stupid".
We're gumming up our own works by agreements here and there. As far as we know, we have a tact agreement with the Skaven (I once ran a WFRP campaign based on the Skaven sheltering in the Empire - they backstabbed us in that as well), seem to be assisting the HE, who (with the exception of Teclis I have no respect for at all), and now seem to be working along side the damned Druchii!.
At the start of the campaign we allied with the Bretonnians. The other races didn't seem to want to know, and still don't really have any interest in our fluff or objectives. So long as we stay true to our objectives and make sure we keep our ar*es covered, we'll be okay.
And let the pointy ears say that they'll grab this and grab that - we all know that the heart of the Empire is a dark one, and no-one rules the forests for long. With all our technology and advances, the forests are still places to be fearful.
Oh, and I nailed the Lizards on Sunday.
