Legend
True, but I wouldn't even say that these themes are particularly exclusive. To put it another way, there are powers that resemble others across power sources.Well, its mostly fluff. There's some broad mechanical themes running through the various power sources.
To elaborate upon my previous comment about "restriction", I was mostly imagining the silliness associated with, "They can't publish <whatever race> before <blank> power source!!!1! WHat about there powerz?!!" which I find to be mostly BS. I feel that this development strengthens the validity of my position slightly.
FWIW, I sure wouldn't mind seeing some published feats that, for example, give some bonus to all Martial exploits or Arcane spells. I would like if there was a little bit of direct mechanical influence behind power sources.
