As for this idea, it is really not "done" at all. It stands as a declaration without any work done on it.
It needs examples. Even if it does not have specific examples, it needs general ones to illuminated. Then it needs one to three of your spell lists.
As it is right now, it is a 1. It is not well written, it is not well defined, and there is not enough material here to raise it beyond that.
Oh yes, can you capitalize the title?
I am also wondering what system you are used to looking at? Not that you need to stat thigns that way, but to give us a point of view. Your declaration is not stunning or innovative for most of us, as we are not used to Vancian magic or Locked spell lists. Go to Comment
A culture believes that souls are recycled. One child gets half of a soul, another child gets the other half. However, this means that with each passing generation, the amount of soul in the child will become less and less (Through division)until their culture will die in the future because of their soulless offspring.
