Intro. Before the creation of ninja villages, the world lived in constant war, dominated by mercenary clans hired to fight. The two most powerful and rival clans were: Senju clan – known for balance, strength, and desire for peace. Uchiha Clan – masters of the Sharingan, proud and powerful, but driven by emotion and revenge. These clans fought non-stop, always hired by opposing sides, causing a cycle of hatred and death that dragged on for generations. It was in this scenario that Hashirama Senju and Madara Uchiha were born, two boys who became friends in secret and dreamed of a world of peace. But when they grew up to be leaders of their clans, they ended up fighting each other, even as Hashirama tried to form an alliance. The war reached its peak until Hashirama proposed a truce—which led to the founding of Konoha, the first ninja village.

The alliance between the Uchihas and Senjus.
