Lion El'Jonson - Subjugation of Sarosh: The Dark Angels' 4th Expeditionary Fleet under the command of Lion El'Jonson took part in the continued Compliance of Sarosh (officially codified as Sigma Five-One Seven but known to the Dark Angels as Four-Three, the third world brought to Compliance by the 4th Expeditionary Fleet), which had formerly been commanded by an officer of the White Scars Legion.Lion El'Jonson went in answer to a call for aid from his brother, Jaghatai Khan. Of all the primarchs, the Khan stood closest to the Lion, for despite their differences each appreciated the honest and forthright nature of the other, and so the Lion was ill-disposed to ignore his call.The Sarosi -- ruled by a planetary bureaucracy -- had recently expressed their interest in becoming part of the Imperium, and the Imperials were eager to allow them in, believing that these people seemed to possess the same secular beliefs as they did in the Imperial Truth. But over a standard year had passed and the Sarosi were as yet no closer to attaining Compliance, constantly apologising to the Imperial planetary governor chosen for their world, Harlad Furst, that their bureaucracy was slowing the process.But the Sarosi (without mentioning it to the Imperial expedition) secretly worshipped Chaos entities in the Warp they called the "Melachim", and saw the anti-religious stance of the Pre-Heresy Imperium's Imperial Truth as unsuppressed evil.After the Dark Angels fleet arrived in orbit to accelerate the Compliance process, the Lord High Exacter, the leader of the Sarosi bureaucracy, who had been invited aboard the Invincible Reason to meet the primarch, denounced El'Jonson and the Emperor to the primarch's face aboard the Dark Angels' flagship, and El'Jonson responded by ramming his power sword through the fanatical Sarosi leader's body.But the Sarosi delegation had also brought a hidden nucleonic device aboard their shuttle, intending to assassinate the fleet's entire command structure, including El'Jonson, in one fell swoop; however, Luther and a junior Librarian named Zahariel El'Zurias managed to eject the shuttle into space, causing only minor damage to the flagship. Luther admitted to Zahariel that he had discovered the device earlier and had briefly considered allowing it to kill his oldest friend, largely because of the jealousy that had begun to grow in his soul.The rebels on Sarosh would be crushed for their treachery, brought to heel swiftly by the might of the Dark Angels and the Imperium's armies, but the victory would leave a bitter taste for many. In the aftermath of the fighting, some questioned the ease with which the Sarosi had infiltrated the Ist Legion's defences, and though none would call what had occurred treachery, there were those whose devotion to the Legion's new path was questioned.Luther, Zahariel and five hundred other Dark Angels drawn from among the veterans of both Terra and Caliban were to find themselves returned to Caliban, not in exile, but neither in triumph.There they were to serve as a garrison force, the overseers of the Lion's sanctuary and to continue the recruitment of new Space Marines into the Legion from the Calibanite population. They were required to leave the Great Crusade behind, regardless of their legacy of standard years in service in either the Calibanite forest or among the stars.This was the determination of the Lion, that he would set aside even those whom he held dearest in the name of duty. Some would name it arrogance and others, with the benefit of hindsight, would call it foolhardy, but it was ever the way of the Lion. It was not the cold logic of battle favoured by some among the primarchs, but the proud imperative of duty and excellence -- that those who faltered be set aside, no matter how justified or small the failing, and the worthy grow stronger through the trials they faced.
