Phylactery - Often taking on the appearance of a small scarab-sized cylinder, a Phylactery is an inconspicuous charm that is actually a powerful Necron self-repair device. A Phylactery is filled with tiny, spider-like nanoscarabs that will swarm over the Necron bearer’s body and wounds at a command, or if he is severely damaged or destroyed. The nanoscarabs then proceed to reknit tears in his ravaged Necrodermis body; bolstering his own self-repair abilities so that he may continue to fight on again.

Primary Awakeners - The first elements activated by a Tomb World's autonomic systems once the outside environment has been judged to be receptive to the hibernating Necrons' awakening are the Tomb Spyders. These robotic custodians begin the initial tasks of opening and performing basic maintenance to the Necron stasis tombs. Imbued with the powers of Necron resurrection, the Tomb Spyders activate the Tomb World's initial reconnaissance forces, known as Raiders. Meanwhile, the second group of Primary Awakeners, the smaller robotic constructs called Scarabs, secure the interior of the stasis tombs. In massive swarms numbering in the thousands, Scarabs seek out intruders and carry out any remaining essential maintenance on the stasis tombs' defence systems.At the same time, it is not unknown for a challenged Overlord to yield to a subordinate if there is no hope of immediate victory. They will choose to wait out the passing Terran years and centuries at a lower rank, patiently anticipating an opportunity to reclaim the power that was lost.

Necron Lords are easily marked out through the elaborate decorations with which they are adorned. In some cases these take the form of ancient, mouldering robes, possibly dating from before biotransference. Others are clad in tabards and cloaks of shining, segmented metal. Perhaps this choice of attire gives some insight into the minds of these immortal rulers, differentiating those who long for a return to flesh from those who embrace their undying form.When the ancient Necrontyr gave up their organic bodies through the process of biotransference at the behest of the C'tan, they transferred their consciousnesses into new machine bodies made of the living metal " necrodermis." The rulers of Coreworlds would inevitably be the close kin to the regent of their dynasty's Crownworld, ensuring a bond of dynastic loyalty endured between the often diverse planets. In the times before the biotransference, such civil wars led to the slaughter of countless millions in a matter of solar days or weeks. But nowadays, the Necrons' cybernetic ability to self-repair enables them to wage such conflicts for years or even centuries with no discernible victor. This is reason enough for all but the most desperate or power-hungry Necron nobles to avoid such an outcome.

A large population centre of one of the galaxy's younger races, usually Mankind, may have been settled unwittingly on what is actually a Necron Tomb World. When this situation is encountered, the Tomb World's encoded programming reacts extremely aggressively to defend its hibernating charges. Asmothep - Phaeron of the Szarekhan Dynasty. When the Silent King, Szarekh, chose to exile himself rather than undergo the Great Sleep, many Necrons felt he was fleeing the mistakes he had made in the War in Heaven. Asmothep, however, was among those phaerons who believed Szarekh had chosen to do so for a greater purpose that was unknown to the Necrons of that time.Such a realm is nothing when compared to the galaxy-spanning Imperium or the Necron dynasties at the height of the glory during the War in Heaven, but it is nonetheless impressive for the work of a mere two hundred Terran years. Sempiternal Weave – A Sempiternal Weave is an advanced form of Necron technology used to augment the Necrodermis bodies of members of Necron royalty. 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. The Stormlord is unshakeable in his belief that only when the galaxy is washed clean with the blood of inferior beings will Necron dominance begin anew. Resurrection Orb - A Resurrection Orb is a glowing sphere that focuses energy into the repair circuits of Necrons around the bearer. This allows them to regenerate at a rate faster than normal upon the battlefield.

This evolving structure is made possible by a system similar to that used in the most complex assemblies of the Adeptus Mechanicus, which is known as Nodal Command. Nodal Command organisation allocates a strict hierarchy to all of the elements within it. This system grants greater operational and decision-making capacity to certain "nodes" whilst slaving the rest of the system to these nodes' autonomous command decisions. Naszar - Overlord in the service of the Sautekh Dynasty. Rules over the Sautekh client dynasty, the Sekemtar Dynasty. As such, certain unusually powerful or large dynasties that spread across more than one sector can have multiple phaerons, who can be subordinate to a more powerful ruling phaeron, as in the Szarekhan Dynasty.He believes in accepting his fate as a soulless Necron and enjoying the immortality it has brought by pursuing endless campaigns with a merry attitude that is as honorable as when he was still a flesh-and-blood warrior. If others choose to see that as insanity, Zahndrekh can live with that stigma. The Necron Overlord represents the supreme ruling class of the Necron machine-xenoform on the battlefield. Acting in turn both as warlords, leading from the front lines of combat, and as field marshals, directing their phalanxes of Necron Warriors and war machines with exacting precision, they represent both the strategic mind and the motivating force of the Necron race. Necron Line Formations - The majority of the units that make up a Necron field army are placed under this extension of the Nodal Command. Led by up to 4 Bronze-level Necron Lords, the Line Formations are made up of a wide variety of Necron fighting units. Ground forces are organised into units called phalanxes, which are made up of a core of Necron Warriors transported by Monoliths and supported by secondary fire support units like Destroyers, Immortals and so on. These phalanxes are often accompanied by units comprised of more specialised Necron troop types known as cohorts. The Necron Lords of the Line Formations serve as a battlefield command circuit that is able to pass data between themselves, upload data to the Platinum-level Necron Overlord or call upon the Reserve Command for reinforcements or a more in-depth analysis of tactical information. Each Tomb World may have dozens of full Line Formations, which are activated as needed by Tomb Spyders and inserted into or removed from the Nodal Command as the flow of combat dictates. Normally equipped with a Staff of Light, Necron Overlords are brilliant strategists, capable of calculating every possible outcome in the ensuing conflict and formulating strategies to ensure that everything goes to plan. But nowadays, the Necrons' cybernetic ability to self-repair enables them to wage such conflicts for Terran years or even centuries with no discernible victor. This is reason enough for all but the most desperate or power-hungry Necron nobles to avoid such an outcome.
