Atekph Dynasty

The Atekph Dynasty was one of the noble dynasties of the Necrontyr Empire. While currently only a part of the dynasty has woken up, a large presence of Necrons in the XoStaurus system has already been reported by the Imperium. They're primarily present on XoStaurus, although more and more Necrons are awakening on the fringeworlds. They are currently ruled by Phaeron Nemesiar the Restless.

Necrontyr Dynasty
The Atekph Dynasty was one of the dynasties from before the War in Heaven, and were one of the more prominent houses in the fight against the Old Ones. The Atekph Dynasty managed to survive the War in Heaven, as well as the rebellion against the C'tan.

The Atekph Dynasty was among the last dynasties to enter the Great Sleep, although the Phaeron, Nemesiar never entered the Great Sleep. Nemesiar was accompanied by his Crypteks all this time. This earned Nemesiar the title Restless.

Awakening
Portions of the XoStaurus system was awakened by the sudden appearance of a Warp Storm, followed by an invasion of the Forces of Chaos on the system. The Forces of Chaos were unprepared for the Necron force that guarded the planet, and it required only a portion of Necron Warriors to drive them back.
