Changes

Lucius continued to hone and better improve his combat skills after the Emperor's Children began to worship Slaanesh. Fulgrim organized gladiatorial games on their new home planet whenever the Legion was unable to vent its need for the pleasure of the kill on other worlds, and Lucius was undefeated in these, an unstoppable force, until he fought Lord Commander [[Cyrius]]. Lucius died, and his death was an experience of such transcendent pleasure that Slaanesh himself took notice: he could not let such a promising marine slip away. In the following days, Cyrius began to change: lines began to appear over his skin , and his hair started to fall out. Lucius was back in the world of the living, and all that remained of Cyrius was a screaming face in the warped [[artificer armour]]. This has happened many times since then: whenever his killer takes even the tiniest moment of enthusiasm, pleasure, or satisfaction from besting Lucius, they will begin to change into him and become just another swirling face, a memory in the armor in which Lucius is clad.{{Fn|1}} Not even the mechanical [[Necrons]] are immune from this curse, as the [[Phasing Sword]] has learned. After every "death" Lucius reborned has been reborn again, as arrogant and maniacal as ever and immediately looking for a new challenge to fight.{{Fn|15}}

After the [[Battle of Thessala]], Fulgrim left his legion to its fate and retired on a [[Daemon World]] called [[Callax]].{{Fn|24}} Many Emperor's Children saw this as a rejection by their Primarch, though Lucius did not.{{Fn|17c}} As Fulgrim was gone, a leadership struggle erupted in the legion, with Lucius, Eidolon, and Fabius emerging as the leaders of the most prominent factions.{{Fn|24}} Lucius was involved in the [[Legion Wars]] and fought in the [[Battle of Skalathrax]],{{Fn|17a}} though his influence among the Emperor's Children ultimately dimished. As time wore on, he was reduced to the leader of a small warband dubbed the "[[Cohors Nasicae]]" after his old bodyguard.{{Fn|17c}} Regardless, he remained an infamous and renowned among Chaos followers{{Fn|17a}}{{Fn|17b}} and continued to operate as Fulgrim's champion. At one point, the Primarch employed Lucius to kill a Fulgrim clone created by Fabius Bile.{{Fn|17c}}

Through Over the course of thousands of years , Lucius hunted down and eliminated a lot of many great duelistduelists. He defeated the [[Emperor's Champion]] of the [[Black Templars]] at [[Veilfate]], the [[Dark Eldar]] [[Archon]] [[Vraesque]] in cursed [[Shaa-dom]] and the [[Ork Warboss]] [[Two-klaws]] at [[Octarius Sigma]].{{Fn|15}} After a series of reversals had reduced the Cohors Nasicae to about twenty Space Marines,{{Fn|17b}} Lucius was forced to cooperate with Fabius to replenish his warband.{{Fn|17c}} In the proccessprocess, he was able to merge his force into a greater warband known as the "Faultless".{{Fn|17d}} Ultimately, Lucius became part of Eidolon's [[Phoenix Conclave]] on [[Harmony]].{{Fn|19}}
