C'tan Shard of the Nightbringer

The Nightbringer is one of the fragmented C’tan, the ancient star gods and sun-eaters enslaved by the Necrons after the biotransference. It is the embodiment of death itself: even its scythe-bearing silhouette stirs a primal terror in alien minds. Each shard is only a sliver of its original power, bound in a necrodermis body that Necron Overlords unleash only when the situation truly demands it. When a Nightbringer takes the field, every living thing around it remembers, instinctively, what it means to be mortal.
