Wait, why am I getting some weird lovecraft vibes from the Urgot-Respawn-VO?

"Echoing from the depths."

"Our rise cannot be stopped".

And finally: "If they could only comprehend the truth of the dredge, I wouldn't need to drive it into their skulls!"

These are the lines he has for coming back onto the field, and the fact that the stuff in front of his mouth kinda looks a bit like tentacles... well, just let me say that lovecraftian horror is not always coming from the abyssal depths of the ocean, but from any dark and usually unreachable place. So if you dig deep enough at the right spot, you might find something horrible - or it will find you.

So Urgot was betrayed and kicked out of Noxus, then get sent into the mines as a broken man, only to emerge completly changed with an ideology he spreads as zealously as a crazed cultist.

Obviously that could all mean nothing, but his there truly was an unimaginable entity of chaos and anarchy buried beneath Zaun - it's not completly crazy to assume, no?
