Sempiternal Weaves are pieces of equipment used to augment the structural integrity of the Necrodermis bodies of Necron royalty and are, therefore, utilised by the Necrons, particularly Necron Lords, Necron Overlords, Phaerons and other high-ranking Necrons.
In a nutshell, the Weave is threaded with filaments of phase-hardened amaranthite and adamantium, vastly increasing the hardiness of the wearer to a level that rivals that of Astartes Terminator Armour. If you thought that regular Living Metal was a pain in the ass to deal with, the Sempiternal Weave would love to have a fine chat with you.
Necrons with the Weave look thiccer, heavier and more rugged than the skinny skelebros of lesser Warriors. If you wonder why big chonkas like Lychguards look so bulky, now you know. Overall, considered an upgrade to normal Necrodermis.
In 8th Edition tabletop, the Sempiternal Weave is considered another wargear option from 5th edition that's found its way back, but with a very different effect. Instead of +1 Sv, now it's +1 Toughness and +1 Wounds. Unfortunately for the Weave, the 'Crons now have better relics to utilize.
