Mr. Ward,
I am sure those with a tuned medical capability, especially in the anesthetic field, will be difficult to come by, as this is not a skill often trained in these regions of the underdark, and, of course, it is exceedingly rare for a trained physician to survive his or her way down from the surface. Furthermore, you know as well as I do that the tools and equipment, not mentioning the resources themselves, are also difficult to come by. Should you give up on a search for an expect of anesthetics, my chemical expertise will always be at your disposal, as you may know, but do not exaust yourself seeking one who does not exist.
Aside from that, I have a certain political endowment that needs to find its way into your hands. I hope it does soon.
Strife
