C'tan - Inactive or Unknown Status: The names of several other C'tan are known to the Imperium of Man and the Aeldari, though they have not yet been encountered as active C'tan Shards and it remains unknown whether they still exist in Necron captivity like their brethren or have ceased to exist.Iash'uddra the Endless Swarm - Nothing is currently known about this C'tan, other than that it exists.Kalugura - Kalugura is a C'tan who was captured and transformed into a C'tan Shard. Kalugura was once a horrific engine of destruction. This particular C'tan Shard was entombed on the world of Kalugura aeons ago, at the command of the Silent King Szarekh, then the supreme overlord of the Necron race's ruling Triarch. The reason why this Shard was imprisoned and is no longer deployed by the Necrons is unknown.Llandu'gor, the Flayer - When the Necrons finally turned against the C'tan in the last days of the War in Heaven, the Flayer was not simply splintered as were his brothers, but utterly obliterated. In his dying moments, the Star God inflicted a terrible curse upon the Necrons, tainting them with an echo of the fathomless hunger of its essence. The victims of this terrible madness are the Flayed Ones.Og'driada, the Arisen - Nothing is currently known about this C'tan, other than that it exists.Tsara'noga the Outsider - Tsara'noga the Outsider became insane due to its consumption of other C'tan, a trick played on it by Cegorach, the Aeldari Laughing God. It developed a hellish presence, causing madness in all who came close, and many killed themselves rather than have to face the Outsider. The Outsider shares some similarities with the Nightbringer, in that it is said that to look upon it would cause terror, much like the Nightbringer's infusion of terror in the younger races produced by the Old Ones. Furthermore, one of the Harlequins' many dances depicts the moment when the Laughing God tricked the C'tan into consuming each other, except that the C'tan depicted is the Nightbringer, rather than the Outsider. The Outsider is currently imprisoned in a Dyson Sphere located beneath the galactic plane. The Harlequins whisper that "one dark night, it shall return."Yggra'nya, the World Shaper - Yggra'nya is also known as the "World Shaper," the "Moulder of Worlds" and the "Worldmaker." The World Shaper's thoughts can break apart planets and reshape them into forms more pleasing to itself. A shard of this C'tan powered the planetoid-sized mobile Necron Tomb World called Borsis, the "World Engine." Prior to the Silent King Szarekh's betrayal of the C'tan during the closing days of the War in Heaven, Yggra'nya was the patron deity of Borsis, the World Engine. During the days when it still ruled Borsis it had manifested as a being with skin of multi-coloured flame. Its form then possessed several pairs of arms, each carrying a symbol of rulership: a sceptre, an orb, a sword, and the jaw of a spacefaring beast. Topping its three-eyed face was a headdress of gold and deep blue. Borsis was one of many worlds Yggra'nya controlled when the C'tan ruled the Necrontyr as their star gods. Like other C'tan, it was shattered into C'tan Shards when the Silent King betrayed the star gods in the closing days of the War in Heaven. In 912.M41, the Nephrekh Dynasty Necron Lords Turakhin and Heqiroth overthrew the Magadha Dynasty Necron Overlord who ruled the crownworld of Borsis and activated the World Engine. The World Engine, powered by a great shard of Yggra'nya, made its way to Mars, destroying any Imperial worlds in its path, with the intent of awakening the the C'tan known as the Void Dragon. Heqiroth had also stolen the living metal skin of Yggra'nya, declaring himself a god. During this time, the shard of Yggra'nya mentally contacted Brother Ghazin of the Astral Knights, who were desperately battling the World Engine alongside other Space Marine Chapters. Yggra'nya and Turakhin both assisted the Astral Knights in return for their freedom and to bring down the now-mad Heqiroth, respectively. Yggra'nya appeared in a vision to the Astral Knights' Chief Librarian Hyalhi. It took on an emaciated form composed of grey matter, wearing a tattered headdress of gold, dull oval eyes of crackled amber, and an empty mounting for missing gemstones. It raged against the betrayal of the Necrons, believing there was no fault in what the C'tan had offered to the Necrontyr when they had traded their souls for their undying necrodermis bodies in the biotransference process. Yggra'nya offered to destroy Borsis in exchange for assistance from the Imperials in freeing it from its prison. It claimed that it would simply leave the galaxy afterwards to find a new home whose inhabitants would prove more appreciative of its gifts. After destroying Borsis, it fulfilled its promise to disappear, but Inquisitor Lord Quilven Rhaye had made his own pledge to Chief Librarian Hyalhi to find and destroy Yggra'nya. In 999.M41, during the Second Battle of Damnos, another shard of Yggra'nya was deployed by the Necons against the assaulting Imperial forces. After the Ultramarines under the command of Chapter Master Marneus Calgar reached a stalemate with the Necrons on Damnos, a psychic communication from Chief Librarian Varro Tigurius informed Calgar of the nature of the Tesseract Vault that was being used to attack the Imperial positions. Calgar ordered his forces to focus their fire upon the Tesseract Vault, which when destroyed release a C'tan Shard of Yggra'nya. The shard of the World Shaper proceeded to wreak havoc upon the Necrons, the Imperials, and the world of Damnos itself. This shard of Yggra'nya opened vast subterranean chasms across the planet, destroying most of the Necron and Imperial forces. With the tide turned against the Necrons, the Ultramarines 2nd Company Captain Cato Sicarius hurled a Vortex Grenade at the shard of the World Shaper. Turning its horned head to leer at Sicarius, the C'tan shard summoned a giant fist shaped of bedrock from the ground to grasp the Ultramarine captain. Just as the fist began to close upon Sicarius to crush him, the vortex grenade detonated, sucking the C'tan Shard into the Warp.
