The Prince That Was Not Promised
The Uchihas along with the Senjus were the founding fathers of the Konoha Province. The Senju House, their closest allies, turned their backs against them and one of the reasons was to gain favorence and strengthen their alliance with the other houses that lived in the Konoha Domains. These Houses feared the Uchihas because of their power and for their tendencies to succumb to madness. And the Senjus too, were growing suspicious of the power-hungry House. Because of their growing resentment and paranoia towards the Senju for banishing them to a corner of the land, the Uchihasons decided to revolt against the Senju oppression: they would invade the Senju's landing and take hold of the government facilities and depose the King, Hashirama. Albeit, unknown to the Uchihas, the Senju House found out about the Uchiha rebellion through their infiltrated spies that posed as household staff.
In the dead of the night and in cold blood, the capital of the Konoha province, Senju's landing, sent a royal cavalry to the Uchiha lands to wipe out the Uchiha house from the rolls of history, before they attempted to overthrow their ruling.
Even today, few sources remain, and no one will tell the tale. But perhaps the truth still remains in the abandoned castle of the House Uchiha, waiting to be unearthed by an adventurer. For nothing is ever truly forgotten in the eyes of Lady Destiny. The entire incident was covered up by the Senju government and the fallen house was struck from every record book. But the tales and legends survived among the inns and bards across the land. One of the many tales known to some is that of a prince of the Uchiha that survived the massacre. And this prince vowed to himself to avenge his fallen house. Perhaps someone still knows the truth of this ancient tale.
