[@Gisk] You would get more points as the Roleplay goes on and your character grows, sometimes it would be in bursts or gradual, and you're also subject to loss of points say in case of a crippling injury (spiritual, mental or physical) for long term or short term depending on the severity and type of injury.

The difference between Attack and Keyblade Proficiency is simple. Attack refers more to a character's raw physical strength and physical inflicted damage, Keyblade proficiency on the other hand refers to their ability to handle the keyblade and their knowledge of the weapon. To demonstrate: A character can have a good amount of physical strength but doesn't know how to wield a keyblade or use it properly to its optimal extent. Maybe another character doesn't have much forte in the strength department and is more magic oriented but he knows how to handle a weapon like the keyblade and can use it with some knowledge unlike the former character I mentioned. 

Star Wars and Marvel are not included I am afraid, just to make sure we don't stray off too much from the main plot, although this is subject to change should there be demand for a world based in one of them.

CS could be submitted when a proper OoC Thread is made, however, you're free to come up with at least some skeleton for the character/characters you want to roleplay. 

And you're free to choose what home world they come from, just don't stray too far off out of the Disney/Final Fantasy/Kingdom Hearts umbrella. You're also free to make up a world of your own should you feel the need to.

Also, don't worry about asking too many questions :) , if you have more I'm all ears.
