Rise of the Nakamura
The capital of Musashi Province, Edo Castle was invaded twice in a short period of time by the Hojo Clan and subsequently the Nakamura Clan. After the castle fell under Nakamura control, Hojo Ujiyasu reacted by dispatching firebomb-wielding ninja to raze the town.
Thanks to the leadership of Nakamura Eiji, casualties from the burning of Edo were kept to a minimum. Refugees from the destroyed castle town have since moved to the East, seeking shelter in the other Nakamura provinces. Eiji has sworn to rebuild the castle town following his return from war.
