Editing Lion El'Jonson (section)

===Fall of Caliban===
{{Topquote| How? How can this be? Do you realise what you have done? That you have doomed yourself is terrible, but in so doing you have condemned your brothers, and even Caliban itself, to damnation. And for what? Look around you, Luther! Look at what you have become. Look at what this has done to us all. What promise did they make you that you would barter away your soul? What could be worth this price? |Lion El’Jonson, last recorded words of the Primarch during the Battle of Caliban}}

{{topquote|Damn you Luther – how could you betray us? We were your brothers, and now we must join you in eternal damnation.|Lion El’Jonson, Primarch of the Dark Angels}}

The events after the Horus Heresy are unclear; the forces of Chaos had been defeated, but they had left the Imperium in ruins. For the Lion and his Legion, one final, shattering betrayal remained to be discovered on their return to Caliban. As the Angels' unsuspecting fleet moved into orbit, they were met by a devastating barrage of defence laser fire ''(ordered by Astelan)''. Stunned by the attack, the Lion withdrew and attempted to find out what had happened. Luther had used his skills at oratory to lead the Dark Angels under his command to turn their backs upon the Emperor and their Primarch.

The fury of Jonson and the loyal Dark Angels at learning this information knew no bounds. They had fought from one end of the galaxy to the other and now they found that their own homeworld and their own brethren had turned against them. The Lion immediately ordered an assault on the planet. The massed guns of the fleet easily disabled Caliban's defence laser batteries and then scoured the planet, driving the rebel Dark Angels back to their fortress monasteries. The Lion personally led the assault on the greatest of the monasteries, knowing that this was where he would find Luther. The two opponents were equally matched, for Luther had been enhanced by the dark gods of Chaos, becoming a psyker of such power that not even the combined might of the Watchers could restrain him. [[Anime|The two former friends met in a combat the likes of which would not be seen again. The two combatants moved with inhuman speed and agility, their blade movements too fast for any observer to follow. When they connected, the impact produced shockwaves that shattered the massive cathedral, causing chunks the size of battle tanks to fall around them as they dueled. At the apex of their titanic struggle they had levelled the monastery but still they continued the battle amongst the ruins.]]

Meanwhile the massed guns of the fleet carried on pounding the planet, reducing the other fortress monasteries to rubble. As Caliban itself started to break apart under the bombardment, the battle between the Lion and Luther reached its climax. Luther, weakened by the long combat, staggered and fell, leaving himself open to a death blow, but the Lion could not bring himself to strike the finishing blow. As he hesitated, Luther unleashed a furious psychic attack that knocked the Lion to his knees and left him mortally wounded. At that moment, it was as if a curtain had been lifted from Luther's eyes, and he realised the full extent of what he had done. The truth shattered his sanity and he slumped down beside Jonson, no longer willing to fight.

A rent appeared in the very fabric of space and a Warp storm of unprecedented fury engulfed Caliban. Those 'fallen' Dark Angels who had served under Luther were sucked from the face of Caliban into the warp and scattered throughout space and time (read the Legacy of Caliban trilogy to find out who was responsible). Caliban, already weakened by the loyal Dark Angels' bombardment, was ripped apart and destroyed.

The Dark Angels flew down to the surface of what remained of Caliban and in the heart of the ruined wasteland they found Luther, who constantly repeated the same words over and over again: the Primarch had been carried away by the Watchers in the Dark and one day he would return to forgive Luther for the terrible sins he had committed. Of the Lion himself, there was no sign.

<s>The Dark Angels took the biggest remaining chunk of Caliban and turned it into their Fortress-Monastery, calling it "The Rock," and to this day, the Dark Angels and their successors hunt down "The Fallen," to torture them until they have confessed their sins and have been granted absolution, then execute them.</s> THERE WAS A SMALL ACCIDENT AND CALIBAN WAS DOWNSIZED BECAUSE IT WAS TOO BIG ANYWAY. IT'S COOL, WE GOT THIS. NOTHING TO SEE HERE, '''MOVE ALONG'''. The Lion is currently fully healed in a regenerative stasis-induced coma in a hidden section of The Rock, making him the only '''other''' loyal Primarch confirmed to be alive as of M41. The 7th edition goes at bit further by stating that when the clarion call of battle sounds for the last time, Jonson will be summoned forth from his millennial rest to defend the Imperium of Mankind from its enemies. Then shall all traitors quake in fear, for the Lion’s vengeance will be terrible indeed... And as of September 2022, if the model leaks are to be believed, that day might be sooner than later.
