Mantis Warriors - Mantis Warriors: The Mantis Warriors, also known as the Mantis Legion, is a Loyalist Space Marine Chapter. It was created to help relieve their progenitors, the White Scars, in monitoring and countering the many threats harboured by the Maelstrom Warp Storm in the Ultima Segmentum, and fragments of records indicate it may have been raised during the 8th Founding of the mid-34th Millennium.The Mantis Warriors eventually were ordered by the High Lords of Terra to become part of an alliance of four Space Marine Chapters known as the Maelstrom Warders that also included the Astral Claws, the Charnel Guard and the Lamenters.The Mantis Warriors held guardianship over the stellar region of the Maelstrom Zone known as the Endymion Cluster that contained a large number of human-settled Feral and Feudal Worlds.When Chapter Master Lufgt Huron of the Astral Claws declared that the Badab Sector had seceded from the Imperium in response to demands by the High Lords of Terra that seemed to be unjust intrusions upon the traditional autonomy of the Adeptus Astartes, the Mantis Warriors joined with the Astral Claws and the other Maelstrom Warders Chapters to defend what they saw as their rightful prerogatives and their Emperor-given duty to protect the people of their Maelstrom Zone region as best they could.The Mantis Warriors, like the other Maelstrom Warders Chapters, did not know that Lufgt Huron, in his hubris, had fallen to the desire for power and the temptations of Chaos.When the civil war known as the Badab War concluded, the Mantis Warriors sought and received the Emperor's forgiveness after the Inquisition determined that there was no Chaos taint upon them.It was determined that the Mantis Warriors' actions had been driven by an honest mistake and the deceits of the man now known only as Huron Blackheart, Traitor to the Emperor and servant of the Ruinous Powers.The Chapter was stripped of its traditional guardianship of the Endymion Cluster, which was handed over to the Fire Hawks Chapter, while the Mantis Warriors were charged with undertaking a penitent crusade for 100 standard years during which they could recruit no neophytes to make up their losses.The Chapter's homeworld of Ootheca and its primary recruiting world of Tranquility III was handed over to the Space Sharks Chapter.In the course of their penitent crusade, the Mantis Warriors found their numbers sorely eroded.However, following the Chapter's participation in the defence of the strategically important world of Herodian IV from a Tyranid splinter hive fleet in the late 41st Millennium, the Inquisition ruled that the Chapter had paid its penance to the Emperor and could begin to recruit once more to replace its great losses.But due to their historic crimes, the Chapter received no Greyshield Primaris Marine reinforcements after the birth of the Great Rift when one of the Indomitus Crusade's Torchbearer fleets reached it, leaving the Mantis Warriors terribly understrength and still on their near-ruinous crusade.Nevertheless, they utilised the Primaris technology and Adeptus Mechanicus personnel given to them by the Torchbearers to as good an effect as they could, creating reinforcements of Primaris Space Marines to bolster their devastated numbers.
