Drat, I was somewhat hoping there might be more knowledge of it here.

[ The disappointment in his voice is genuine. ]

My personal knowledge is distantly academic at best, but there was someone back from my home [ Or, home planet, at the least ] who studied the aetheric density of battlefields, with some sort of utilization of the energies. I believe there was brief discussion of the applications towards things that might otherwise demand similarly bloody costs, but, again, my own personal knowledge of the subject is limited, and I had little time enough to pursue the results of his studies further than their distant mention.

I was hoping someone more native might know of something similar. And, well, you already have a battlefield to draw from.
