The Bilgewater Event might have been a mistake storywise
Don't get me wrong, the story was good, but the aftermath of it, and in leaving the story unfinished, will come back to haunt the characters and the game. Gangplank is semi-insane right now, you can tell. There is no reasoning with him and his need for revenge. He's willing to see Bilgewater burned to the ground if the city is not his again. This can only end with the death or enslavement of Miss Fortune, the death or arrest of Gangplank (either would remove a character from the game), the destruction of Bilgewater, or Bilgewater being taken over by another world power which is why GP joined the LOL in the first place to avoid.
Also, Miss Fortune can't hold Bilgewater. She took it through scheming, and not though a brute force of will like GP. The streets were left in open warfare at the end of the story, which will weaken Bilgewater and make it a tempting target. She also made 2 new enemies, Graves and Twisted Fate. She was willing to kill them to kill GP. So to keep Bilgewater she would have to reach out to outsiders, such as Swain the General of the Noxian army who wants GP dead for stealing his ship The Leviathan, but that would introduce Noxian influence if not rule in Bilgewater.
So if Riot willing to kill characters permanently? Or is it going to be the loss of Bilgewater? If the latter, what does that mean for the Harrowing? It took GP and MF to fight against the Harrowing, what now?
Questions, questions.
