Village Hidden under the Dragonfly

Village Hidden under the Dragonfly is a small village introduced in the Konoha 11 filler arc that was located in the Mountain Country. Thirty years before the series begins, it was at war with Konoha. After a surprise attack by Konoha, they declared a cease-fire. Two days later, however, another village wiped them out. Only Gennou, who had been in Konoha at the time, survived its destruction.
