Duty and Honor
A prominent courtier (and known Gozoku supporter) and his family have been murdered en route to a meeting at court. The PCs are asked to assist a famous magistrate in the pursuit and apprehension of the criminal in question.
The magistrate proves himself to be a capable and honorable man during their tracking of the ronin, and also shows that he too supports the Gozoku reign. With the PCs helping him, he tracks the assassin to an abandoned shrine.
The one who committed the murder was a former samurai turned ronin: when the group arrives, she is preparing to commit seppuku. When confronted, she claims that the courtier using lies and treachery to murder her lord, and she was only avenging his loss. She asks only to be permitted a warrior's death. The magistrate, however, is unwilling to allow such a thing as an honorable seppuku after such a crime. In the end, it will fall to the PCs to decide the ronin's fate (and the consequences to themselves).
Gifts and Favors
The PCs are asked to attend a celebration arranged by a neighboring lord. None of the party has ever met the lord in question, but he has a reputation for being an enemy of their beliefs (whether Gozoku or Imperialist).
During the festival, the PCs learn that the lord has been using his political contacts to gain political support in exchange for military favors. One of their allies asks the PCs that the lord be dealt with in order to remove his influence.
A few years ago, the lord's lands were stricken with drought and debt, and he found no one else to turn to for help. He has no love for the politics involved in his current life, and has used much of the money to restore his province and people to prosperity. The PCs must decide whether to follow the orders as dutiful samurai, accepting the fact that without the lord, the province will likely fall into ruin once more.
Master of Bushido
The PCs have been asked to escort and protect an aged monk to a celebration in the Imperial City.
The monk knows little of politics or combat, but is considered a foremost master on the subject of bushido. He will need both physical and social bodyguarding, something which the PCs may or may not be prepared to supply.
Once the PCs arrive, they find that both the Imperialist and Gozoku courtiers are trying to bribe the master into speaking for their views on bushido. The monk sees flaws in both, but the PCs must deal with the gifts, threats and advances of skilled Shosuro, Doji, and others trying to win their support.
