'''Canoptek Tomb Sentinels''' are [[Necron]] constructs used for guarding the confines of [[Tomb World]]s. Designed by the [[Cryptek]] master-artificer [[Toholk the Blinded]], at the order of the [[Silent King]] the Tomb Sentinels were distributed to [[Triarch Praetorians]] for wider circulation across [[Necron Dynasty|Necron Dynasties]] before the [[Great Sleep]]. Acting as both a guardian and attack construct, the Tomb Sentinel is a heavily modified [[Tomb Stalker]], forgoing the Stalkers Stalker's close combat capability in place of the [[Exile Cannon]]. The Tomb Sentinel is capable of phasing between realities, allowing them to bypass the defences of lesser races and tearing them to pieces in close confines.{{Fn|1}}
