On Kingdom Roles
Again, you won't be forging a new kingdom until you are around level 4 or 5, but it's not a bad idea to have an aspiration. At the very least, the following will give you a better idea of what will be expected of your character as your kingdom is made.
Also, as this will be a frontier nation, you will be going on adventures as well as governing, and there will be NPCs available to keep things running when you need to go be heroes.
Ruler: Important Ability: CHA.
The ruler (baron, duke, king, queen, duchess, tzar, emperor, or whatever title you decide upon) calls the shots! All executive decisions are made by him, and his presence directly contributes to a nation's economy, security, and morale. A nation without a ruler can claim no new territory, build new cities, roads, or farms, and slowly falls into unrest.
There can be two rulers in a nation: a married couple, whom both contribute to their nation's power.
Councilor: WIS or CHA
This trusted advisor represents the voice of the common people. They are responsible for organizing festivals and other important activities that boost the nation's morale.
General: STR or CHA
Leader of the nation's armies, the general is a public hero and inspirational figure. Wartime tactics rest largely on his shoulders. The nation's stability and security benefit from the presence of a talented general.
Grand Diplomat: INT or CHA
This advisor and statesman is head of foreign relations with other nations. This role requires knowledge of foreign customs, the ability to maintain composure and dignity, and a certain amount of neutrality, to be able to pierce veils of pride, tradition, or ignorance. The Grand Diplomat also has the power to issue promotions to individuals who have proven their worth, and deals with issues of nationality and immigration.
High Priest: WIS or CHA
The High Priest is one of the nation's most influential religious leaders, and is responsible for the spiritual wellbeing of its people. While there may be more than one faith in the nation, the High Priest's influence often determines the most popular or dominant faith. An active High Priest contributes to a nation's stability and peace of mind.
Magister: INT or CHA
Head of the nation's academic and magical fields, the Magister is a foundational element of a new nation's budding culture. A skilled Magister can draw academics, artists, and mages to their nation, increasing its economy.
Marshal: DEX or WIS
The Marshal (or sheriff, etc.) is tasked with patrolling the nation's territory and keeping the peace. Invested with the power to enforce justice within the nation's borders, the Marshal extends the reach of the ruler to outlying sectors, isolated towns, and backwaters. The security of roads and trade routes depends on a skilled Marshal, and the nation's economy benefits accordingly.
Royal Assassin: STR or DEX
The Royal Assassin is either a professional killer tasked with eliminating problematic individuals, or else a headsman, executioner, or King's Justice. Whether working behind the scenes or in the open, a Royal Assassin benefits their nation through fear (ideally striking it into the hearts of potential criminals and revolutionaries, but to the common folk as well to a certain extent). The people's loyalty to their nation can be increased by an effective Royal Assassin, and the role is unique in that it can actively reduce unrest; a nation suffers no penalty for not having a Royal Assassin, for the less squeamish ruler.
Spymaster: DEX or INT
An informant, information broker, master of whispers, and trusted councilman, the Spymaster is responsible for monitoring the nation's underworld, observing black market trade, the activity of thieves and bandits, and investigating corruption, sedition, and intrigue. Not a role for the weak of heart, the Spymaster operates alone or with a network of informants, using subtlety and skill to control crime, as well as weaseling out plots against the kingdom, from within or without. This role is unique in that the benefit it provides the nation can be altered, whether boosting the nation's economy, stability, or morale, it's all up to the Spymaster.
Treasurer: INT or WIS
Not usually a popular role, the Treasurer is nevertheless a vital individual, for without one the nation cannot collect taxes, robbing the nation of funding for defenses, public works, and expansion. A just and attentive Treasurer can become the best friend of merchants, workers, and visiting dignitaries, while a greedy or corrupt one can become a scapegoat, public effigy, or target for assassination.
Warden: STR or CON
The Warden (or Captain of the Guard/Watch, etc.), is leader of a nation's defenses, city guards, and constabulary. While the General leads the field army, the Warden often commands the garrison and standing army. The Warden also works closely with the Marshal in maintaining the peace, and benefits a nation's loyalty and morale.
