Zahariel - Sarosh Campaign: The newly trained Dark Angels Librarian Zahariel was assigned to the 22nd Chapter of the Dark Angels. Shortly after their entry into the Great Crusade, the 4th Expeditionary Fleet of the Dark Angels reached the orbit of the planet Sarosh, which had formerly been under the perview of Shang Khan of the White Scars Legion. For whatever reason, the Saroshi appeared to intentionally put off the inception of the Imperial Compliance process they had agreed to diplomatically.The Imperials believed that these peaceful people seemed to possess the same secular beliefs as they did as embodoed in the Imperial Truth. But the Saroshi (without mentioning it to the Imperial expedition) secretly worshipped Chaos entities in the Warp they called the "Melachim," and saw the atheistic stance of the "Imperial Truth" as nothing less than pure evil. Later, a Saroshi delegation came aboard the Lion's flaghsip, the Invincible Reason. Led by the Lord High Exalter, the leader of the Saroshi bureaucracy, they agreed to discuss the issue of Compliance with the primarch. The Lord High Exalter then proceeded to formally denounce the Emperor to the Dark Angels' collective shock.Meanwhile, Luther and Librarian Zahariel waited in the embarkation deck to deploy to the surface of Sarosh. Out of curiosity, Luther suggested to his Battle-Brother that they investigate the Saroshi shuttle. The commander's interest was piqued, for the shuttle was thousands of Terran years old -- a functioning relic of an earlier age. Upon further investigation, the Legion's second-in-command went utterly pale. Zahariel noticed the change in Luther, who appeared pallid and had a strange expression. The commander dismissed Zahariel, telling him to rejoin his company until he was called for.Zahariel left the Legion's second-in-command at the door to the embarkation deck, watching as Luther stared in fascination at the Saroshi shuttle. But the young Librarian's prescience nagged at him with the feeling that something was terribly wrong, and so he rushed back to the embarkation deck. Upon closer inspection of the shuttle he discovered a dark device that had been hidden in a secret compartment of the shuttle's nose.Luther informed the Librarian that it was some kind of atomic weapon. The Saroshi were obviously intent on assassinating the Dark Angels' entire command hierarchy, including the primarch. Zahariel was confused by this startling revelation and wonder why Luther had not revealed this truth earlier. Luther informed the confused Librarian that he had wanted to, but then he had thought of what could be his if he didn't: the Legion, command, Caliban. It would all be his, and he would no longer have to share it with someone whose shadow obscured everything that he did.Zahariel argued that the Lion's deeds were great, as were Luther's. Luther explained that his deeds might have been great in another age, one in which he did not share the same span of time as a man like the Lion. In any other age, the glory of leading Caliban from the darkness would have been Luther's, but instead it had gone to his brother. He told Zahariel that he had no idea how galling it was to be the greatest man of the age and have that taken from you in an instant.After a solar decade or more, the feelings that had been contained within a dam of honour and restraint were finally erupting, and Luther's true feelings spilled out. Zahariel had had no idea that Luther was so consumed by jealousy and ego. The commander told him that no one in the Legion did, and not even he had realised the full extent of his feelings, not fully, not until he saw the bomb placed aboard the Saroshi shuttle. All he had to do was not lift a finger and walk away, and everything that he had ever wanted would be his.Luther had ordered everyone out of the embarkation deck and walked away, but he hadn't gone more than a few steps before he knew that he couldn't do it. Luther had come to realise that it was an honour to serve a warrior as great as the Lion, and that he was the luckiest man alive to be allowed to call him brother. With the help of Zahariel, the two Dark Angels managed to open the embarkation deck's outer doors, the shuttle and its makeshift bomb hurling into the void of space as the deck decompressed. The nuclear blast wave from the warhead's detonation only caused minor damage to the Dark Angels' flagship. They had managed to save the Lion's life.During the uprising that followed on Sarosh against Imperial rule, the Lion led his Dark Angels to the world's surface. They soon encountered one of the dread Warp entities summoned by the Saroshi. The Melachim threatened to overwhelm the Dark Angels force, including their primarch, with a powerful psychic assault. Libararian Zahariel would prove instrumental in defeating the fell creature, when he used his Bolt Pistol to slay the host body so that the vile Warp entity could not fully translate into their reality. Zahariel joined with the senior Librarian, Israfael, focusing his innate abilities on the foul creature. The powerful psychic attack banished the creature to whence it came.
