Genshin Impact: Is Ei the Raiden Shogun (Baal)so yae called Raiden as "Ei" in the trailer, what are y'all theories about this? could this be raiden's real name? 🤔 pic.twitter.com/dVBgNFSwtQ— Daily Baal (@dailybaal) August 20, 2021During the Genshin Impact 2.1 trailer, Yae Sakura refers to the Raiden Shogun (Baal) as Ei while speaking to the Traveler. She questions him, asking if he believes his ambition is enough to shake Ei's will. This may have been the reveal of Raiden Shogun's true name, though others like Venti and Zhongli know her as Baal. As an Archon, Raiden Shogun has many titles, but Ei might be her name in the human world. This is somewhat similar to Zhongli leaving behind the name "Morax."RAIDEN SHOGUN NAME REVEALL - Ei mihoyo really went, since her name in Honkai is mei, why wont we just take off the "m" 😭😭😭. jokes aside,I think they named her Ei, just like her cons' reference style from the kanji character of the word Eternity; Ei#GenshinImpact pic.twitter.com/aMkTkqg4n3— gelo🦊 | future yae miko haver🌸 (@foxyyae) August 20, 2021The truth of the Raiden Shogun's identity is still a mystery, as she is an enigma even to those in Inazuma.
