The additional undead forces you requested for your enterprise has been denied. It seems the undead are having problems in the north with an unidentified foe and all available forces have been diverted there. Exactly what the problem is, they are not saying.
I suspect the unidentified foe is giving them more problems than they are letting on.

However, you should have recieved the shipment of herbs, scrolls and other oddments we gathered to help in your work. It's not as much as we had hoped but until the undead resolve their own problems we are pretty much on our own.

Keep us informed of your progress.
