Editing Caliban (Warhammer 40,000) (section)

===Fall of Caliban===
After the Heresy, the Lion and the Dark Angels showed up, after having not heard from Caliban for over a decade and none-the-wiser about what had been happening at home. They were fired upon when their ships entered Caliban orbit, and they quickly determined that Luther and his Dark Angels had fallen to Chaos. The orbiting Dark Angels responded by sending Lion to confront Luther while their ships opened up with an orbital bombardment.

Either way, the bombardment, compounded by a miniature [[Warp]] storm unleashed due to third-party time-travel shenanigans from the 41st millennium from various factions including the [[Death Guard]], [[Fallen Angels]] and the [[Dark Angels]] themselves caused Caliban to break apart; the largest piece was that which contained the fortress-monastery whose reinforcement meant that it withstood the attack and shielded the surrounding rock, which the Dark Angels re-captured and used as their headquarters, calling it '''[[The Rock]]'''.

The Angels on the surface were scattered through the Warp and became the [[Fallen Angels]]. Many became full [[Chaos Space Marines]], though many more become thoroughly disgusted by both Chaos and the Imperium and went renegade (disgusted by Chaos for being demonic and disgusted with the Imperium because...umm...just...because the writer said so, I guess).

As of 8th Edition, it's revealed that a continent-sized chunk of Caliban survived relatively unscathed and escaped the system somehow, and is housing a small legion's worth of Fallen. Though precisely what they're doing on it is anyone's guess.
