Unlike their Necron masters, Canoptek Spyders never sleep, but wile away the aeons servicing the structures of their Tomb World, guarding their slumbering superiors and maintaining the complex stasis machines that house them. Even in their prime, these systems required constantly looped maintenance cycles lest they degraded beyond repair, and the withering centuries have only hastened this natural decay. It is a task both endless in scope and thankless in nature, but Canoptek Spyders are patient unto eternity. After the tomb’s primary sentinel computer, Canoptek Spyders are the chief coordinators of a Necron tomb’s guardians.
