Yeah here's another scenario from me!
This one is really good (it's true).
You are Minamoto, a skillfull samurai from the
Shiorita Clan. The Shiorita Clan was a small clan in
Japan in the middleage. It has been peace for a long
time in Japan, but now the Shogun has died and the
peace is broken by several Chinese clans, Japanese clans
and even by some Mongols. This is very dangerous for
our clan, since we aren't prepared for things like this.
We haven't got an army and not even a defense. If our
clan shall stand and not fall we must establish a
militarycamp, with a Castle, and train soldiers and
samurai. We shall strike back and be the hordes over
Japan and over some areas of China! Minamoto shall be
the next shogun over Japan!!!
