Urgot Rework theory
I got here thinking about what happened last winter; a champion from a certain region in Runeterra was released then a champion was reworked that ties into the lore of that new champion that was released.
This got me thinking. And then there was the Kayn interaction videos I've watched recently that mentions there being 2 more unknown Darkin creatures out there and also the theory that Darkin's are actually weapons that have the ability to possess the bodies of those that wield them.
Urgot could be one of them, or more likely, a forge of a Darkin weapon and Zaun tech, creating this disgusting creature of death.
We've seen what Zaun is capable of with the Warwick update. This will just further that understanding and fear.
Let me know what you think and if you have anything to either back-up or deny this.
