The practices of the Moshi shugenja were developed over the course of many years spent in unwavering devotion to the Sun Goddess. Despite the celestial upheaval that has occurred within the Celestial Order during Rokugan's history, the Moshi have managed to retain their devotion even if the nature of their magical studies has changed somewhat. Since joining the Mantis Clan, their focus has shifted from one of pure theology to more practical concerns, and they excel at invoking the kami who hold sway over the weather. As such, the Moshi, who are far more numerous than the modest Yoritomo bloodline that maintains its own shugenja tradition, are frequently stationed aboard Yoritomo vessels in order to placate the seas during the clan's all-important mercantile voyages.
Like their Yoritomo kinsmen, the Moshi are highly adaptable. Their ability to gain an additional Affinity during the day, particularly since it is not accompanied by an additional Deficiency, allows them extreme versatility in their spell-casting choices, enough to rival even the Isawa of the Phoenix Clan.
