====Infestation====Known as the '''Second City''' of [[Necromunda (planet)|Necromunda]], Secundus was a place of architectural and arboreal beauty,{{Fn|1}} as well as a centre of learning and enlightenment.{{Fn|2}} Those that lived there also lived comfortable lives when compared to Necromunda's other [[Hive]]s.{{Fn|3}} All this came to an end, though, when one of Hive Secundus' scholars attempted to concoct a [[Genestealer]] anti-gene, that would prevent the [[Xenos]] from infecting a population. The [[Genestealers]] the [[Heretek|renegade]] [[Biologis]] [[Hermiatus]] used for his unsanctioned experiments eventfully escaped in 879.[[M41]], however, after one infected him. Hermiatus would flee Necromunda afterwards, while the escaped Genestealers went onto infect a large number of the Hive's population,{{Fn|4}} which led to the [[Genestealer Cult|creation]] of the [[Cult of the Second Son]].{{Fn|5}} Necromunda's [[Planetary Governor]], [[Cyar Helmawr]],{{Fn|6}} was made aware of what was occurring in Secundus, but he waited too long to deal with the infestation. By the time the Hive World's military forces finally attempted to purge Hive Secundus' of its corruption, they were unable to do so. Cyar was later publicly executed by the [[Inquisition]] for his failures in keeping Necromunda safe{{Fn|7}} and he was succeeded as Planetary Governor by [[Kael Helmawr]].{{Fn|6}}

====The Dust WallContainment====

During those years, Kael also prepared to contain the threat by ordering Hive Secundus was surrounded by thousands of miles of fortifications. These would be manned by hundreds of Necromunda's PDF,{{Fn|1}} and Enforcers{{Fn|8a}} who would ensure nothing escaped from Secundus to threaten the rest of the Hive World. This was named the '''[[Dust Wall''' ]] and when it neared completion, the Planetary Governor halted efforts to save Secundus and instead he began preparing to destroy it. Those forces that were outside of Secundus were withdrawn to safety, while those still fighting within it were abandoned and considered lost. Most of the underground tunnels linking Secundus to the rest of Necromunda's Hives were also destroyed or sealed off before its end came. Once these preparations were completed, The Planetary Governor had Hive Secundus bombarded from orbit with [[Nuclear Weapon]]s{{Fn|1}} and [[Graviton Missile]]s.{{Fn|2}} This laid waste to the Hive and Secundus toppled to the ground, as the weapons continued to raze the thousand square miles that surrounded it as well.{{Fn|1}}

However despite Hive ====Destruction====Those forces that were outside of Secundus' destructionwere withdrawn to safety, while those still fighting within it were abandoned and considered lost.

Once these preparations were completed, The Planetary Governor had Hive Secundus bombarded from orbit with [[Cult of the Second SonNuclear Weapon]] survived and they continue to dwell within its ruins.s{{Fn|1}} The weapons used to destroy Secundus, though, have mutated the and [[Xenos]] into a unique sub-species of Genestealers known as the [[Malstrain Genestealer|MalstrainGraviton Missile]]s.{{Fn|2}} Because of Secundus' continued threat This laid waste to [[Necromunda (planet)|Necromunda]], the '''Dust Wall''' has remained to ensure its inhabitants do not escape from it - or that anyone attempts Hive and Secundus toppled to enter the Hive. Those who man its wallsground, tolerate Necromundans sneaking into as the no man land between the wall and Hive Secundus' ruins in order weapons continued to plunder raze the wreckage and bodies therethousand square miles that surrounded it as well.{{Fn|1}}

However despite Hive Secundus' destruction, the [[Genestealers]] and the [[Cult of the Second Son]] survived and they continue to dwell within its ruins.{{Fn|1}} The weapons used to destroy Secundus, though, have mutated the [[Xenos]] into a unique sub-species of Genestealers known as the [[Malstrain Genestealer|Malstrain]].{{Fn|2}} ====Recent Activity====Despite the '''Dust Wall''''s efforts to guard Hive Secundus, though, the [[Genestealer]]s and the [[Cult of the Second Son]] have infiltrated its' underground tunnels and they now attack anyone who use them to reach the Hive's ruins.{{Fn|5}} Despite the dangers in doing so, some Necromundans enter Secundus's ruins to plunder its riches or hunt the Hive's dangerous inhabitants. This includes the [[Spyre Hunter]]s of the [[Hive World]]'s [[Noble House]]s and the [[Tek Hunter]]s of the [[Clan House]] [[Van Saar]], who will often work together within Hive Secundus, so they can each accomplish their own goals.{{Fn|2}} Some Malstrain Genestealers and members of the Second Son have also managed to escape Secundus as well and have gone on to establish footholds on Necromunda{{Fn|4}} and even create several new [[Genestealer Cults]]:{{Fn|9a}}{{Fn|9b}}
