From publisher blurb:
A Ninja's Honor is a One Shot Adventure entirely written in one page and free of RPG systems (system agnostic). The story it set in a Feudal Japan genre in the Edo Era where players take the roles of mercenaries/ninjas hired by a Feudal Lord (Daimyo) to get rid of rebelious leaders in the region.
Background Story
In the Edo Era the Nanbu Clan was a powerful legion that had the entire dominance of the northeast part of Japan and just like any powerhouses there are going to be rebellions inside their people. A group of Shinobi is hired by the Daimyo, Nanbu Naofusa, to get rid of the main leaders of the rebellion in the region.
Naofusa has been kidnapping and threatening men from small villages of the Nanbu region to go work in their farms. These men are treated pretty much like slaves, so some of them decided to flee and create a group that has been terrorizing rich towns around the land and killing nobles and guards.
As the players investigate they might choose to take the side of the farmers that want to kill the Daimyo or to finish the rebellion leaders and finish their jobs.
