Nearly all the playable characters in Genshin Impact have Visions, which they received from one of the Seven Archons.
Ever since the Liyue chapter in Genshin Impact, we learned in-game that The Raiden Shogun, the current Electro Archon, is confiscating the Visions of those in Inazuma.
Because of that, many players started to believe this why is miHoYo has yet to add new Electro characters.
Some fans believe there’s a lore reason behind that: the Electro Archon’s current motivations and the Vision Hunt Decree.
