Corewar
The Corewar was a battle between the Necrons of the Oltep Dynasty and the Daemonic legions of the Daemon Prince Beublghor on the world of Cocholos in 052.M40
Overview
In 052.M40, the Necron Lords of the Oltep Dynasty finally awoke on their Tomb World of Cocholos to find their planet's inner fires dead. Realizing that during their slumber an entire Imperial civilization has come and gone, the lords of the Oltep Dynasty send their Necron Warriors deep into a mysterious subterranean network to determine why their world is now a lifeless orb. They eventually find the truth in a colossal hollow sphere at the planet's core, where the Daemon Prince Beublghor now makes his lair. The titanic entry, having grown powerful after slaughtering the human population of Corewar, notices the Necrons and transforms in a gigantic armored leech with a Warp Portal in place of a head while ordering his Daemonic legions to attack. Battle rages in the darkness, and the Necron armies are undone when Beublghor's tunnels begin to shift and flow into new shapes. The Daemon Prince and his innumerable Bloodletter hordes crush the isolated Necron strike forces one by one. With the Necrons obliterated, their metal skulls are heaped in a pile within the planet's cold womb.[1]
