Bilgewater: Hooray for backwards-compatible lore
I rather enjoyed the new Bilgewater lore, not least because (unless I've missed something) it's largely backwards-compatible with the established lore, and for that matter with the League of Legends.
At least on my first read, nothing stood out as incompatible with prior lore. The closest it came was the uber-dark "torturing people for kicks" Gangplank, but GP was always supposed to have a scary side. (I do wish the writers would have gone with something a little more original than a torture scene for their kick-the-dog moment. But hey, it's quick and effective. We see a character torturing somebody, that's a clear signal that this character is scary.) It didn't turn TF into a lizard-man or make MF Ionian.
And hey, there was a suit of Demacian armor! It's almost as though someone from Bilgewater might have had contact with Demacia! That's a nice break from the "ahhh, legends do tell of a strange place known as _______, but perhaps they are only stories!" approach.
