Lore
In the past, Yae Miko taught Ei how to place her consciousness into objects.[2] This technique allowed Ei to create the Plane of Euthymia, her inner world[1] which she placed within the blade Musou Isshin.[3]
The Plane of Euthymia is part of Ei's plan to achieve eternity for herself. Over 400 years ago,[Note 1] she successfully created the Shogun, an identical puppet whose body would not succumb to death or old age, and left this puppet in charge of pursuing Inazuma's eternity. Ei herself secluded to the Plane of Euthymia, a space which reflects her inner world, to meditate and prevent the erosion of her spirit.[1] Ei can still monitor the outside world from within the Plane of Euthymia, and can assume control over the puppet's body at will.[4]
Present Day
In the past few hundred years since entering the Plane of Euthymia, Ei neither permits anyone to enter the Plane of Euthymia nor leaves the Plane to check on Inazuma.[4] Because she only cares about affairs which directly pertain to eternity, she pays no attention to everyday life in Inazuma, and despite understanding the circumstances behind the Vision Hunt Decree, deems this irrelevant to eternity and tacitly approves it.[2]
This state of affairs is finally broken during the Archon Quest Amidst Stormy Judgment in Chapter II: Act II - Stillness, the Sublimation of Shadow, after the Traveler interrupts the Vision Hunt Ceremony. The Traveler's ability to use the elements without a Vision marks them as an exception and thus an "enemy of Eternity," causing them to be brought into the Plane of Euthymia for Ei to personally judge their strength. The Traveler's consciousness leaves the Plane after their defeat, but the fact that they met Ei at all piques Yae's interest.[4]
Traveler returns to the Plane of Euthymia during the Archon Quest The Omnipresent God in Chapter II: Act III - Omnipresence Over Mortals, allowing Yae to enter using her connection to the Grand Narukami Shrine Omamori that she gave them beforehand. They show Ei the light of the Visions inlaid in the Statue of the Omnipresent God[5] which, combined with her defeat at the Traveler's hands, finally shakes her will and convinces her of the potential within human wills and dreams.
After the Inazuma Archon Quests, Ei turns off many of the Shogun's functions as she deliberates their future course of action in their pursuit of Eternity and declares that the Raiden Shogun is resting. The Traveler and Paimon visit the Shogun to investigate some concerns held by the people of Inazuma, and after receiving less-than-helpful replies from the Shogun, Ei brings them into the Plane of Euthymia. There, the two convince Ei to take a personal tour of Inazuma, leading her to visit Inazuma for the first time in over 400 years.[6] Afterwards, Ei starts involving herself more with Inazuma's affairs and assumes control over the Shogun's body more often — which then leads her to conflict with the Shogun, who judges that Ei may have succumbed to erosion.[7]
Trivia
- The English localization of the Magatsu Mitake Narukami no Mikoto Materials' descriptions refer to Raiden Makoto's realm of consciousness as the "Plane of Euthymia," but it is fundamentally different from Ei's Plane of Euthymia[4][8] and is never referred to as a "Plane of Euthymia" during the quests which involve it. Not even Yae Miko fully understands what realms of consciousness are, only that the nature of the space is different from those created by the technique of storing consciousness inside an object.[8]
- In the original Chinese text, the text corresponding to "Plane of Euthymia" in the materials is simply 净土 Jìngtǔ, "Pure Land," whereas Ei's Plane of Euthymia is almost always referred to as the proper noun 「一心净土」 Yīxīn Jìngtǔ, "Pure Land of One Mind."
Etymology
- The original Chinese name refers to the Sino-Japanese concept of "one mind" (Chinese: 一心 yīxīn; Japanese: 一心 isshin), also translated as "wholeheartedly," which is also referred to in several other terms related to the Raiden Shoguns, including Musou Isshin and the Raiden Gokaden's Isshin Art.
Notes
- ↑ According to Wanderer's Character Story 2, Ei entered the Plane of Euthymia the same year that the Tatarasuna Mystery occurred. In the Archon Quest The Night-Bird Falls at the Curtain's Call in Interlude Chapter: Act III - Inversion of Genesis, Sawada found government records which showed that the people involved in the Tatarasuna Mystery lived over 400 years ago.
