Sempiternal Weave

A Sempiternal Weave is an advanced form of Necron technology used to augment the Necrodermis bodies of members of Necron royalty, such as those of Necron Overlords, Necron Lords and Necron Destroyer Lords. A Sempiternal Weave threads a Necron’s exoskeleton with filaments of phase-hardened amaranthite and adamantium, vastly increasing the body’s hardiness to a level that rivals Astartes Terminator Armour.
