Battle of Drugne: the First Legion finds themselves out-matched by a barbarous horde, only to prove undefeated after the aid from a crazed, lone wanderer.

Rune Wars happens at some time around this point. It's unclear if this particular war happened at a similar time to the Rune Wars in the southern continent or if Noxus was even involved in this War at all. What is likely though, was that this war resulted in the exodus of the proto-Demacians. As well as evaporation of Leblanc's public influence upon history.

An elite group of warmages known as the "Arcane Fist" were surprisingly decimated after an expedition into the Greenfang mountains near Demacia. It was their magical presence that awoke the Colossus Galio for the first time.

Following his death, the Black Rose uses the dark magicks at their disposal to resurrect Sion's body. With his unnatural strength, unwavering rage and insatiable bloodlust- Sion is reborn a monstrous war machine.

Shortly after, Noxus retaliates against Demacia. It is upon the fortress in Andras that Sion is unleashed for the first time since death. Enemies and allies alike were to become the casualties of the juggernaut's rampage.

Many great battles, successful or otherwise have taken place over the course of Noxuian history- the Battle of Fallgren; Siege of Rugg; Siege of Qualthala; Assault on Glorft; Sacking of Trevail; the Draken Campaign and the Siege of Fenrath.

But as the years roll on, the ambitions of the empire expands beyond its initial borders and with every extension of their sovereignty does the grip of the nation stretch thin. Legions on the furthest outskirts are even left to their own devices because the empire is unable to maintain discipline.

Casting down Darkwill from his throne and crushing him in view for all to see. Swain takes the role as the new Grand General of Noxus and pulls back the warhosts from Darkwill’s unwinnable campaigns and, with the establishment of the Trifarix, ensured that no individual can rule unopposed.
