About

1598: The 3rd Year of Keicho Sixteen years have passed since the revolutionary of the Warring States, Oda Nobunaga, vanished in the hellfire of Honno-ji. The realm was unified by Toyotomi Hideyoshi, who inherited Nobunaga's ambition and rose to the absolute peak. However, the throne of the realm drove Hideyoshi to madness. It began with the premature death of his brother Hidenaga, followed by the early passing of his first son, Tsurumatsu. Losing his support, Hideyoshi became a tyrant, forcing his nephew Hidetsugu and his close tea master Sen no Rikyu to commit seppuku, and slaughtering their entire families. As if bearing the weight of these sins, the ruler of the realm has now collapsed from illness at Fushimi Castle. Into whose hands will the fractured realm fall? Chaos hungers for a hero. Instructions for AI: Use archaic, period-appropriate language. Do not use modern terminology. Characters who have died must never be brought back to life. Characters should generally use formal language (keigo) with anyone they are not close to. Do not introduce modern objects. Do not jump immediately into battles or raids; depict the subtle political maneuvering beneath the surface.

This is something I've wanted to make. I'm running out of characters and word count... It's still quite incomplete, so please be gentle... There are parts that don't align perfectly with historical facts, but please overlook them...
