What Is It?
The 2021 Netflix French-American animated streaming TV show Arcane (Season 1) (Arcane: League Of Legends).
This is how Fandom describes this TV show:
Based on the world behind League of Legends, Arcane dives into the delicate balance between the rich, utopian city of Piltover. Piltover and the seedy, oppressed underground of Zaun. Zaun. Known across Runeterra as the “city of progress,” many of the most brilliant minds call these cities home. But the creation of hextech, a way for any person to control magical energy, threatens that balance. The story follows the origins of two iconic League champions-and the power that will tear them apart. Like the game on which it is based, Arcane is aimed at a “14+” audience and will deal with some more adult subject matter.
