In 052.[[M40]], the [[Necron Lord]]s 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 sent their [[Necron Warriors]] deep into a mysterious subterranean network to determine why their world had become a lifeless orb. They eventually found the truth in a colossal hollow sphere at the planet's core, where the [[Daemon Prince]] [[Beublghor]] had made his lair. The titanic entry, having grown powerful after slaughtering the [[human]] population of Cocholos, noticed the Necrons and transformed into a gigantic armored armoured leech with a [[Warp Portal]] in place of a head while ordering his [[Daemonic]] legions to attack. Battle raged in the darkness, and the Necron armies were undone when Beublghor's tunnels began to shift and flow into new shapes. The Daemon Prince and his innumerable [[Bloodletter]] hordes crushed the isolated Necron strike forces one by one. With the Necrons obliterated, their metal skulls were heaped in a pile within the planet's cold womb.{{Fn|1}}
