Fists Exemplar - War of the Beast: The Beast had begun a massive invasion of the Imperium's worlds in the Ultima Segmentum and Eidolica was one of the earliest to feel the great Greenskin warlord's wrath. Without any warning one of the Beast's Attack Moons appeared in Eidolica's orbit and launched a massive planetary assault on the Space Marine homeworld that the surprised Fists Exemplar were unable to contain. Within the first solar hours of the invasion, Chapter Master Alameda was killed and command fell to First Captain Garthas until he too died at the Orks' hands.As their homeworld fell further under the Orks' control, Second Captain Maximus Thane took command of what remained of the Chapter within the fortress-monastery of the Alcazar Astra and prepared to defend Eidolica to the last warrior, from within its armour-plated walls. As Thane was making preparations to defend the Alcazar Astra from another Ork attack, he was contacted by the Black Templars Marshal Bohemond, whose crusade fleet had arrived in Eidolica's orbit. The marshal brought ill tidings and said that besides the continued defence of the fortress-monastery, the rest of Eidolica had fallen to the Greenskins and there was no further point in fighting a battle that would only lead to the Fists Exemplar's destruction.Bohemond declared he had come to evacuate what remained of the Chapter, so that they could fight to save other worlds of the Imperium from the ravages of The Beast's Ork forces. Though Maximus Thane resisted the marshal's entreaties at first, he eventually acquiesced to reality and agreed with Bohemond that Eidolica could not be saved. Thane gave the order for the surviving Astartes of the Fists Exemplar to evacuate to the Black Templar fleet in orbit.Thane and the remaining Fists Exemplar later attended the meeting of the Imperial Fists Successor Chapters in the Phall System. The remnants of the Chapter took part in the failed assault on the Ork Attack Moon that had materialised over Terra, and Thane was subsequently dispatched by Koorland to find another of the Imperial Fists successors, the Soul Drinkers. Meanwhile, forces of the Chapter under the command of the Fists Exemplar's First Captain Zerberyn entered into a dark alliance with an Iron Warriors warband of Heretic Astartes under the command of the Warsmith Kalkator in hopes of being able to fend off a massive fleet of Orks by combining their forces.The Fists Exemplar were next dispatched by Koorland, now the lord commander of the Imperium, to Mars to take the tech-priest Eldon Urquidex into custody. The standoff with the Adeptus Mechanicus quickly turned bloody despite the efforts of both sides to prevent violence, and the Fists Exemplar engaged in a short but bloody standoff with the Mechanicus' Skitarii armies before the tech-priests finally backed down and handed over Urquidex.Later, the Fists Exemplar took part in the hunt for the primarch Vulkan on Caldera and the failed first invasion of Ullanor Prime alongside other Imperial Fists successor Last Wall forces.By the start of the second invasion of Ullanor Prime to try and slay The Beast, the Fists Exemplar had been whittled down to a complement of only 73 battle-brothers from the remains of the three companies that had survived the fall of Eidolica.In the aftermath of the War of the Beast and after the discovery of the treachery of Captain Zerberyn in allying with Traitor Marines and his role in slaying the Black templars Marshal Bohemond when the zealous Black Templars refused to allow Zerberyn's Traitor allies to leave Imperial space peacefully, Maximus Thane declared that the Fists Exemplar were to be erased from Imperial history. Its few surviving battle-brothers were sent to found new Chapters of Rogal Dorn's lineage and their very existence was classified by the Inquisition. A new Chapter inherited the world of Eidolica and the Alcazar Remembered as its fortress-monastery.
