Iron Kingdoms - Legends of The White Company
The Greylords Covenant is an organization dedicated to the research and development of magical spells, armaments and devices. The group is largely responsible for providing the Khadoran military with warjack cortexes, runeplates, mechanikal arms and even truly magical weapons such as the infamous Fellblades.
It’s whispered throughout Khador that the Greylords serve their own agendas first and the Empire’s second. Those rumormongers that speak these opinions too loudly often disappear without a trace, lending credence to the belief that the Greylords are always listening.
