Forces
A Force (or Alignment as it may be referred to at times) is not so much a character's intentions, but the actions they take.
Their Fate, their Destiny, the Divine Providence - whatever it may be, they are inevitably tied to one of three groups: Those who seek the restoration of the worlds which have fallen at the hands of the heartless, those who seek - or whose actions inevitably will result in - their fall, or those who are either too wavering or complex in mind to be defined by the other two.
When a character is created, they are placed into one of these Forces. A Force is what ties all the various groups with all of their differing goals together in the grande scheme of things. Narratively, these groups are those most likely to 'join forces' or have some common goals. It is unlikely for a character to change from Force of Restoration to Force of Ruin - and vice versa - although it is not an impossible occurrence. However, it is likely that those of the Wandering Force who get influenced enough by the other two Forces, might come to step into their path - as hearts get connected.
There can be situations where someone of the Restoration alignment may stay out of a fight if they don't agree with their group's decisions. There can even be times where groups within the same Force may be at odds with one another. Not everyone gets along, not everyone agrees, and not everyone has the same ideas on how to accomplish a similar goal.
In very basic terms, this also means that if you are a citizen of Vector, you might be in a 'Ruinous' group, but still be 'good' yourself. Association does not make an alignment. It's the actions your character takes, or will take! If you are unsure where your character falls, you can always look to staff for suggestions, or simply place them as a Wandering Force.
Forces of Restoration
The Forces of Restoration are those people whose actions will eventually end up assisting in the restoration of the Worlds. They may wish to protect their own word, or to fight off the Heartless. Some of these may not be grande people - but their actions will end up making a difference. They do not need to be of purest light. They don't even need to have a strong heart. As long as their actions lead to Restoration, rather than Stagnation or Ruin.
These are your Princesses of Hearts, your Clouds, your Aeriths, your Ramzas and your Edges.
Forces of Ruin
The Forces of Ruin are those who desire power for the sake of power - or at the expense of others. They are those whose hearts might be controlled by the Heartless or the Shadow Lords. They desire conquest, selfish gain, or may simply be those misguided individuals who have placed their faith and loyalty with the wrong people. These people may not see themselves as the 'bad guys', but their goals and plans will ultimately lead towards darker ends and the collapse of the worlds.
These are your Sephiroths, your Kefkas, but also your Vayne Solidor and Gastons.
Wandering Force
The Wandering Force comprises of people who are not among the Forces of Ruin, nor the Forces of Restoration. They can be your commoners, your merchants, or your rebels without a cause. Those who fall among the Wandering Forces can be the chaotic type whose actions sometimes lend them to either side of a battle, your mercenaries who don't care what happens to the worlds, or those who have their own morality which sometimes walks the line between Light and Darkness. Like anyone else, they have their own friends, family, allies and enemies, goals and beliefs, but what sets them apart is that they are not pursuing actions which would ultimately lead to the salvation, or destruction of the worlds.
These are your Maurices, your Jack Sparrows, your Fox and your Setzers.
