Overthrowing Noxus (Theory, Story and a Possible Future Event)
**Short Explanation: **for me it all began with the Shurima event, when
killed
to steal her Chakram in order to open the tombstone, by doing so Cass showed us that she was more than aware of what she was going to find, and it seems that in comparison with her judgement and old lore, she wasn't so surprised of ending up becoming the serpent/gorgon/naga she is now.
But what does this mean? that she needs a LOT of power for a task, a difficult and complex task, because turning your seld into a hideous serpent to release 2 powerful ruthless beings just to take them into the league makes no sense, specially with her personality; everything has a purpose, she is skillful and wants to control and deceive persons.
So that up to this point we can even make a list of champs that could participate in such a plot in very different ways (Im going to make a possible History anyways).
NOXUS:
**
Du Coteau Guild:**
&
(Cassio Friends)
Blackrose Guild:
&
(quite mindless or wicked)
Noxus Neutrals:
(Darius has his suspects on Swain, and Draven is just glad to kill people).

Possible Appearances
and even maybe
and
.
Possible Plot and THEORY:
It all began when
started to search for the track of the missing Du Coteau General, wich lead him straight to Demacia, the place where the Summoner's Rift is ran, the League of Legends. Somebody here, somebody from Noxus is responsible for the desappearance of Du Coteau, maybe somebody here knows something, maybe somebody here has watched something... When Quinn was released it was hinted that she knows how Talon works and his modus operandi, up to a point were we can assume they know each other closely.
Who is the most famous spy/ranger of Demacia? Quinn, t is very likely she has some information about the whereabouts of Du Coteaou, and it may not be a good new for Talon, it will surely confirm his suspects, Du Coteaou is dead, and somebody in the government is guilty, the Blackrose.
In this point we could even assume that Quinn and Talon relationship can go beyond just interest and information (add some spicy comment and music here).
Talon ends up telling the news to the Du Coteau crew, just to find that Cass has some new friends and a new look that fits her personality. Cass tells him she suspected it for a long time, and that it seemed obvious. Her father wasn't a fool, yet he was loyal, and the only thing that could have made him dissappear like that was his own loyalties: he was betrayed.
Cass managed to enter to the city without being noticed, she wants her new looks and powers to be a surprise, and they are also a surprise to her. She tells Kat, Talon, Xerath and Renekton their purpose; to destroy the members of the black rose completely, how? by taking the government first and eliminating the high corrupted aristocracy.
The siege begins: Xerath is leaded by cassiopeia to the tallest structure on Noxus capital; an ancient church, in there Xerath waits for the moment to strike. Cassio leaves and goes to the military barracks of Noxus, where houndreds of men lie training, disguised with a ridiculous cloak she enters, her tail is partially visible, but she keeps going, until she reaches those that where her target, the old Du Coteau men, and also much of the military forces of Noxus. She takes out her cloak to reveal her new true self.
I am Cassiopeia Du Coteau, if You were loyal to my father you shall follow me
A man tries to charge at her and kill the monster, she blows a poison kiss at him and he falls, dead.
Men follow her, out of fear, out of respect, they follow her, and as she passes she starts to turn all those others that could mean a treat into stone.
Renekton invades the government capitol. As a dark alarm raises, he sees a dark figure in the distance, covered in blood from all those that were crushed in his dark charge; Sion is here. behind you can hear them march, the Noxus forces are coming, and the reinforces from Cassio are yet far. Xerath starts the siege, obliterating multiple enemies as Renekton fights Sion, the carnage begins.
All Noxus is aware of what is happening and Urgot, Draven, Darius and Vladimir won't loose a chance to participate in the carnage.
The news arrive at Demacia as Noxus asks for support, desperate, inner disputes go on Demacia, but Jarvan 3, king of Demacia seems more than willing to help the Noxus Government to crush the Du Coteau forces. We could even say J3 becomes mindless and ruthless, desperate, could it have something to do with Swain's trickery?
As this happens Demacians such as Garen, Lux and Quinn will dissobey the orders of the king, a great war is coming, and many secrets will be unveiled.
While this happens Katarina and Talon infiltrate the headquarters of the Blackrose in order to kill LeBlanc, without knowing the dark horrors they wil find.
Possibilities:
, so far in their lore it is hinted that none of these three are actually humans, LeBlanc is an ancient entity, an "avatar". Swain is a dark being with no known past, and Shaco, well, we could say that by the nature of his powers he is the same spot as LB. Also the Darkrose is know for the necromancy of Sion and Urgot, so that there can be things way beyond hardcore horrible in this plot.
