Add Game Settings in CS

[Falistor]

Hi everybody :)

I just wondered if it is possible to add new game settings in the CS, and how to reference them so that they are applied in the game. Does this require OBSE and if so, how do i accomplish it?

I want to make a mod for black soul gems. Basically, i want to create a new soul level (sentient), which has a higher capacity then the current biggest soul level (grand), and make it that only black soul gems have this capacity.

I already found out, that in the CS, there are the Game settings like "iSoulLevelValueGrand" which describes the capacity of a grand soul. So i think i would have to add a game setting "iSoulLevelValueSentient" and reference it so that all Humanoids have this soul level and only the Black Soul gem has the maximum capacity of the "Sentient Level".
Because i have never done a mod before, and have no idea how obse works, i wondered if someone could explain to me how to add new things in the game and how to reference them in the construction set.

I don't have any idea how to help, but it seems like obse may be the way.
