A Necron Lord serves as the commander and energy supply for the much larger Necron armies composed of the standard Necron Warriors. When the Necrontyr gave up their organic bodies to serve the C'tan, they transferred their consciousnesses into bodies made of the living metal "Necrodermis".
However, they soon discovered that over an extended period of time, their new robotic bodies dulled their minds and their ability to feel any type of emotion or pleasure. Over many millennia, the ultimate outcome of this process of gradual desensitisation was that the Necrons became the soulless warrior-slaves of the C'tan, harvesting intelligent life from across the galaxy to feed these souls to their insatiable masters. Only the most powerful and strong-willed of the Necron nobility, referred to as Necron Lords, managed to gain access to Necrodermis bodies following biotransference that were sophisticated enough to allow them to maintain their full sentience in the face of the growing dullness of their minds.
A Necron Lord is a high-ranking member of a Necron dynasty's noble hierarchy and is usually placed by the dynasty's Phaeron or his own Overlord in control of an entire Tomb World. Clad in crumbling vestments and wielding ancient, arcane staff weapons, the Necron Lord is a chilling sight to behold on the battlefield as they direct their Necron Warriors in unnatural silence. Their ancient metallic bodies are marred by the patina of age and they wear the accumulated power of millennia like a robe. With every silent gesture, glittering arcs of viridian energy surround them as their empty eye sockets burn with soulless fire. [Source: wikia]
