Thousand Sons - Age of Secrecy, M32-M41: First Battle of The Fang (Unknown Date.M32) - During the 32nd Millennium, Harek Ironhelm had risen to command the mighty Space Wolves Chapter as its Great Wolf. After the end of the Horus Heresy, Magnus the Red was determined to have his revenge for the devastation of his homeworld of Prospero at the hands of his former brother Leman Russ and his Legion. He devised a cunning plan to lure the Space Wolves into a trap in order to enact his final vengeance against them. Despite the grievous damage Russ had inflicted on them, the Thousand Sons still had the potential to launch raids into protected space, and the knowledge of that burned within Ironhelm. It had burned within him for decades, until nothing else seemed important. Despite all the resources he devoted to hunting Magnus, the chase had always come up short. There were always signs left behind for them to find, mocking hints, challenges to catch the originator of the ruin. After many fruitless efforts to catch up with the Thousand Sons, Harek became obsessed, and took to searching worlds along the edge of the Eye of Terror itself. Eventually he found what he believed to be the Thousand Sons' secret base on the world of Gangava and launched a full-scale planetary assault against it. In this he was deceived, for though Gangava was held by a strong garrison of the Forces of Chaos allied to Magnus, they were but a distraction. Even as Harek attacked Gangava, the fleet of the Thousand Sons and their Chaotic levies appeared in orbit over Fenris. The Fang, the Space Wolves' fortress-monastery, was held only by a skeleton force of Space Wolves and their feudal thralls. For forty days and forty nights the Thousand Sons assaulted the mighty citadel. Bjorn the Fell-Handed, the most ancient of the Space Wolves' Dreadnoughts, was awoken from his long slumber and took charge of the Chapter's defences. Under Bjorn's direction, the Space Wolves fell back to the innermost chambers of The Fang, collapsing the tunnels as they went. Simultaneously, a force of Scout Marines, under Haakon Blackwing, managed to escape from the citadel and take ship to Gangava, bringing word of the siege to Harek. Overcome with fury and shame at his folly, the Great Wolf immediately took ship to Fenris, bringing the might of the Space Wolves with him. Finally, on the upper slopes of The Fang itself, the Great Wolf met Magnus in battle on the final day of the siege. Ironhelm's assault against the Sorcerer Primarch was stoked by rage, the rage he had cultivated ever since leaving Gangava. The Daemon Primarch proved to be too powerful and slew Harek, but not before taking a terrible wound himself. Before dying, the Great Wolf took solace knowing that his Wolves had already penetrated The Fang. His Wolves would hunt down every invader in those halls, one by one, driven by the remorseless focus that had always been their badge of honour. The Thousand Sons withdrew before the blood-maddened Space Wolves. It was not known by what means the Traitor Marines escaped vengeance. Many did not and were killed in the tunnels. But others, including most of the Traitor Legion's Chaos Sorcerers, disappeared from Fenris at the same time their fleet achieved the in-system Warp jump-points. The Wolf Priests speculated that Magnus himself departed in the same sorcerous manner, though there were no witnesses to his leaving.The Athenaeum of Kallimakus (Unknown Date.M32) - Ahriman travels to Apollonia, where the works of Mahavastu Kallimakus the Remembrancer are guarded by a fanatical sect of warrior priests. These tomes are held in a grand citadel known as the Athenaeum, and contain records of the Thousand Sons Legion from the time of the Great Crusade. After a solar month-long siege, the defenders lie broken before Ahriman's forces. The Arch-Sorcerer plunders the writings from their vault before burning the library to ashes, intending that only he should hold the secrets contained within their pages.Omen of Omniscience (Unknown Date.M32) - Hasophet, Magister of the Mind-Eaters thrallband, receives a vision of his Tzeentch-ordained destiny. He sees a time in his future when he will devour the thoughts and memories of an entire world, and in doing so will achieve apotheosis. The Mind-Eaters embark on the first of nine hundred and ninety-nine rites that will lead to this portended moment.The Feral War (ca. 112.M33) - Whilst mining the Feral World of Aggaros, the Adeptus Mechanicus engage in what at first seems like an embarrassingly one-sided battle – that is until the primitives bring their flame-tongued shamans into the fray. The armies of the Adeptus Mechanicus find themselves burnt from the inside or crushed flat by invisible forces. The retreating Tech-Priests call in an old debt from the Relictors in order to renew the attack. Four days later, the Relictors' 3rd Company fights its way through psychic pyrotechnics of bewildering force to reach the hidden city of primitive tribes. Lining every road are dust-caked statues of the Thousand Sons facing a colossal effigy of Ahriman atop a pyramid of obsidian. When it is toppled, every one of the Thousand Sons comes to life, shrugging off the dust of centuries and opening fire on the Relictors with a hail of bolts. Not one of the Adeptus Mechanicus, nor their Relictor allies, survives.First War in the Webway (579.M37) - A coven of Sorcerers from the Kindled Spirits thrallband conducts a great ritual in the Webway, hoping to gain access to the scream-filled city of Commorragh, the home of the Drukhari. Before their ritual is complete, hundreds of Drukhari, led by troupes of Harlequins, pour from an invisible portal and launch themselves at the Rubricae defending the coven. With their spell sundered, the Kindled Spirits counterattack, their blasts of Warp-flame eventually breaching the fabric of the Webway itself. As the arterial walls of the Webway buckle and collapse outwards, the backlash strands the combatants in a shattered pocket-reality with no way out. There are whispers that the fighting has continued ever since, and that each warrior is fated to die and be reborn in an endless cycle for the rest of time.
