Created by Mata Nui, The Necronites, along with the Intellians, settled on the isle of Nocterra, eventually becoming the island's main inhabitants. The Necronites became weapon smiths and engineers, creating and selling machinery of various kinds to Xia and the Brotherhood of Makuta. At some unknown point in time, the Necronites declared war on the Saursapiens of Archosa, the result of disagreement about the prices Archosa demanded for the tools they made. After three years of war, the two islands were calmed by the Brotherhood of Makuta and made an uneasy truce.
