Fallen Angels - Exile: Officially, Luther and his 500 Astartes had been ordered back to Caliban because the Great Crusade was about to enter a new operational phase, and the Ist Legion was in dire need of new recruits to meet the tasks the Emperor had planned for them. The Lion declared that experienced warriors were needed at home to speed up the training process, and a list of names was drawn up and circulated throughout the fleet.Though supposedly accorded a great honour, Luther felt he and his Astartes had been exiled by the man he had raised as his own son. The departure of Luther and the rest had been sudden, almost businesslike, and at the time it had been assumed that they would be back with the fleet before long.But five solar decades had passed, and Jonson had never spoken of them again -- he no longer even read the regular despatches from Caliban, relegating that task to members of his staff. Luther and the rest seemed to have been entirely banished from the primarch's mind, and as the standard years lengthened into solar decades, rumour and speculation had begun to circulate through the ranks.Luther involved himself in every aspect of planetary administration, from tithe structures to industrial and arcology construction, and Brother-Librarian Zahariel was drawn along in his wake. Caliban's once extensive forests dwindled, replaced by mines, refineries and industrial sprawls. Huge arcologies rose like man-made mountains across the landscape as the planet's population swelled.Civilisation spread across the globe, and the ranks of the Ist Legion increased as Luther found ways to reduce the training cycle for new Dark Angels Astartes from eight Terran years to only two. Meanwhile, reports of Jonson's exploits made their way back to Caliban, swelling Calibanite hearts with pride as the Dark Angels marched from one victory to the next.The members of the training cadre admired each and every token sent back by their battle-brothers of the expeditionary fleets and made comradely boasts of how they would exceed them all when Jonson summoned them back to the fighting.Yet as the solar decades passed, no summons came. Jonson had never returned to Caliban; two planned visits had been cancelled at the last moment, citing new orders from the Emperor or unexpected developments in the current campaign. With each passing Terran year, Luther's promise to the cadre in the castle courtyard sounded increasingly hollow, but not a warrior among them faulted him for it.If anything, their loyalty to Luther had increased during their exile. He shared their burdens and praised their successes, inspiring them by virtue of hard work, humility and personal charisma. Though they would deny it if asked, some amongst the cadre believed that many of their battle-brothers owed more loyalty to Luther than they did to their distant primarch.None could not say why it was so important for Luther to return to Jonson's side. They had all borne their exile with stoicism and dedication to duty, as any Astartes would, and Luther more than most. Of course, Brother Zahariel knew why; the Legion's second-in-command was seeking redemption for what he'd nearly done aboard the Invincible Reason.Luther had discovered the bomb that the Saroshi delegation had smuggled onboard the Dark Angels' flagship and had done nothing about it. For a brief time he'd let his jealousy of Lion El'Jonson's achievements overcome his better nature, but at the last moment he'd come to his senses and tried to make things right.If Luther left Caliban and sought out the primarch to demand a fair accounting and a return to the frontlines, he would be in direct violation of Jonson's orders, and that would be construed as an outright rebellion against his commanding officer. Luther could never countenance such a thing.But if Jonson did nothing -- if he let these loyal warriors sit unblooded on Caliban while the Great Crusade came to a close, it would leave a scar within their brotherhood that would never truly heal. Such wounds tended to fester over time, until the entire body was imperiled by a cancerous rot.
