Sendai Isle

Sendai Isle (千代 小島, Thousand Years Isle) is quiet a large island located between the Land of Lightning and the Land of Water. During the events of the Second Great Shinobi World War, the Second Mizukage and Third Raikage came to an agreement to split the island between the two nations. The upper half refereed to as Gunpō (群峰, Mountainous Range) is under the control of Land of Lightning and the lower half known as Sōgen (草原, Grasslands) is under the control of the Land of Water. As the call for another Great Shinobi World War came, Kirigakure began to advance along the island attempting a siege of Gunpō. The famed Battle of Sendai Isle would take place as a result.
