Diplomacy and AlliancesIn many times an alliance will be needed to take on a greater foe, in many times this will be done to kill the warriors of orochi, Unlikely because of mans natural greed to control territory. In any case most of the times many alliances will be formed in order to take territory, save territory, kill a feared officer, etc etc. This can be done by the person requested an alliance by either sending a letter to such person (note that this message may be intercepted) or sending an officer to the home territory of the person being requested. Now in this case its up to the person whether to help or not but helping someone is not without its benefits. Gaining the trust of an ally can be a mutual effort of protecting each others borders or in need of simple assistance.
The rules of an alliance is that each person will still be responsible for their own territory but they will be requested to gain more territory for another person. When this happens if the person chooses to send aid they may send one to three officers to help with all of the officers own personal troops. The alliance will stand for a set amount of time depending on the agreement, although if a person is of the chaotic or neutral alignment they may choose to destroy the alliance and attack an enemy when they are weakest, taking advantage of those who are weak. Now obviously those who are of the good or virtuous alignment wont be able to do such because they are honorable people who wont do such even if their grandmother told them to.
This is a rather short guide but this is all that is needed.
