Do Piltovans/Zaunites worship God?
And by that, I do not specifically mean the Biblical God of our world, but at least something very similar.
Camille has a voiceline towards Warwick after killing him saying: "Not all dogs go to Heaven.", meaning that Piltovans have a concept of a "Heaven" where beings go to upon death.
Dr. Mundo's bio uses the expression: "god-knows-what", which sounds misplaced if there isn't some kind of singular "God" in the setting.
Ekko has voicelines using the word "Angel" upon buying the item, you guessed it, Guardian Angel, which also seems to imply some kind of pseudo-Biblical God in Piltover/Zaun (granted, I know it is a reference to Ekko's voice actor being the same as the voice actor for Pit from the Kid Icarus series).
Even the item, Guardian Angel, might be an artifact (believed to be?) from this "Heaven", and a hint towards some kind of God existing.
I might just be overthinking things, but Piltover/Zaun has more references to Biblical elements than any other region, at least of those I can think of.
Either they do worship some kind of God, or Riot's just seemingly taken words and expressions from our world and used them without putting much more thought into them, which I doubt, considering they've even gone to the length of explaining why Tacos exist in Runeterra, despite being Mexican food in our world.
Either way, just thought it was interesting to share.
