Is Demacia based on Camelot (arthurian legend)

I was just seeing the video Magic is Rising: Stand With Sylas | League of Legends and into the video i felt like i have watched this before i am currently watching the series "adventures of Merlin" and i felt like it had the same hate for magic heck both even has a morgana

so is demacia based on camelot or is this just a coincidence?
