["NO! IT CANNOT BE! IT'S NOT POSSIBLE! AIIIIIIIGH!!!!"] What was it that I found in the catacombs? Was it treasure? Lost knowledge from our ancient ancestors? Relics of power? Or perhaps something more sinister that not only put me at risk, but risked untold suffering and mayhem loosed upon the whole world?

Or maybe it was just a yellow light in the floor while I was was visting the Ehrenbreitstein Citadel in Koblenz, Germany.

I'm still working through photos from the trip, so alas the answer must wait until that task has been completed. images/Drawings/Sketches/yellow-frank.png
