A study in Grey

A group of Mathematician from Mechanus have begun a project unlike any which have gone before. Their goal is to prove the existence of the Least Common Denominator, the moral factor which is common to all moralities. If they find such a proof, they have theorised that all moralities would shift towards grey. A common ground could be found, encouraging discourse and promoting the development of Unified Morality.   They need not find this LCD, for its very existence would shake the very rock on which so many fundamentalists base their faith.   Recently, the Mathematicians have heard of a ancient sect located in the Outlands, and supposedly the Hinterlands. Although these reports are merely rumours, this sect is believed to be the "proof of the LCD" finding them would be to find the proof...you see on the planes abstract concepts are physical reality.
