Samurai

Long before the arrival of the Sento-ki, the Samurai were the strongest military force to have stride across Yatan. When Samurai were first trained, they quickly filled Yatan's ranks. Before Samurai, soldier's were mostly just typical medieval soldiers. However, there were many periods where specialized soldiers were favored, but nothing like the all around usefulness of Samurai. In modern Yatan, Samurai have been made null, but nations still train and maintain large Samurai armies.
