While Sesshōmaru often dealt with threats that his father had also faced, such as the Panther Tribe and the Four War Gods who had dominated Horai Island, he was nomadic, never claiming any territory or making one place his home, constantly roaming the countryside in search of power and strong opponents.

Later, Sesshōmaru renounced his title after married to his longtimme human companion Rin, now eighteen, that leads to the birth of their fraternal twin hanyō daughters Towa and Setsuna which left the Western Lands unattended and the mysterious Kirinmaru, the Lord of the Eastern Lands began to carry out his plans of bringing forth the Degenerate Age by eradicating all of time via the infinitely powerful Windmill of Time to access the modern era for his own ambitious ends.
