A geothermal pool, once largely ignored, became the site of an encounter between the Ronin and Shogun. The Shogun expressed astonishment upon finding the Ronin enjoying its waters. Legend held that this hot spring was created to mend injuries sustained by knights.
This geothermal pool featured in the non-canon comic Visions 1, a work penned and drawn by Takashi Okazaki, and released by Marvel Comics on October 12, 2022.
