Burning Forest Plan

The Burning Forest Plan (燃える森計画, Moerumori Keikaku) was a project created by Mōretsuna Uzumaki as a way to take revenge on Edagakure for destroying Uzushiogakure. The plan took place over several decades in order for Mōretsuna to gain the necessary reputation, trust and power required for it to work.

The Plan in Theory
Several decades before the start of Sanger Hiden, Mōretsuna was a loyal shinobi to his village who was skilled in espionage and assassinations. When Eda forces invaded the Uzushio, Mōretsuna became trapped in a collapsed building near the beginning of the invasion, preventing him from assisting his village. Following his rescue two days later, he saw the village in ruins. Over the next week, he saw that not only was Uzushio destroyed, but so was the entire Land of Whirlpools. This led to Mōretsuna having a mental breakdown and swear vengeance upon Eda.

Taking the name Mukui, began to study the Land of Rainforests and much to his surprise, learned of a giant, golem-like creature sealed somewhere within the country's rainforests. Knowing he would not be able to find the golem's sealing place easily, Mōretsuna managed to infiltrate Eda under the guise of one of their shinobi.
