The main character?
The “central” character of the story?
The ‘face’?
Whatever you consider that to be, who do you think it is?
I know it’s definitely a bit of a loaded question, so I’m expecting a lot of different answers, but I’m excited to hear them!
I mean, there are MANY arcs in league, bilgewater, shurima, demacia, etc…
So each arc would have a protagonist, Sylas for demacia, Vi/cait piltover, etc…
But if you take the whole Runeterra into account, I’d probably say Ryze, Ezreal or Poppy, whose story arcs encompasses all of the world.
Ryze with the rune searching, Ezreal being the explorer and Poppy looking for a person worthy of the hammer (when the hammer already chose her but she doesn’t know)
