Warhammer 40000: Necrons - C'tan Shard of the Nightbringer

The Nightbringer was once death incarnate – a sadistic god with the power to unmake the stars and a hunger for the life of the galaxy. Like its fellow C’tan, it was shattered by the Necrons, and its insane fragments have ever since been enslaved by those it once ruled. A single shard of the Nightbringer can destroy entire armies. They extrude scythe‑shaped blades from their necrodermis, using them to cull their enemies with great sweeps of entropic unmaking. Their very gaze, meanwhile, is death itself, capable of leeching the essential animus from their victims.
