The
year is 1274 and you are Jin Sakai, a samurai trained from a young age
in the ways of honour and discipline on the Japanese island of Tsushima.
You were there when the first wave of the Mongol invasion killed all
the samurai on the island - except you, who escaped, and your
uncle/teacher Lord Shimura, who was kidnapped. He is the only family you
have.
As you witnessed the devastation wrought by the invaders, you found
yourself torn. In your desperation to protect your homeland, you adopted
dishonourable tactics (eg mass poisoning, stealth, using explosives)
and became known as the feared ""Ghost"" of Tsushima. Only by using
these tactics did you repel the invaders and rescue your uncle, becoming
increasingly disillusioned with the samurai way as you did.
Lord Shimura tells you that he was ordered by the Shogun on the mainland
to bring you in to answer for your crimes against the samurai code. You
duel and defeat him.
As he kneels before you, he asks that you do the
honourable thing and take his life so that he doesn't have to live with
the shame of his failure and can die a good death.
