Necrons - Used

The Necrons are a race of sentient androids who long ago traded away their souls for the gift of immortality. For millennia beyond counting they have slumbered within their tomb worlds, sprawling crypt-fortresses that house billions-strong armies and ranks of deadly war machines. With every passing year more Necrons arise from this long stasis, and as they awaken so they begin the process of reforging their dynastic empires, which once ruled the galaxy with an iron fist.To earn their immortality, the Necrontyr sacrificed their very flesh, replacing it with living metal.
