Well how about one for each story...
Immaculate: Just because something is natural doesn't make it okay, strike out against destiny and wash aside anything that would seek to corrupt you.
Zealots Redemption: Dismissing yourself as eternally damned is nothing but a form of cowardice, a convenient excuse to alleviate yourself of the burden of trying to be a better person.
Birthright: (Heck there's so many... How do I pick one....) Uhhh.... Sibling love is the purest form of love? The banality of civilization is a curse that can only be alleviated by striking out on your own? Exceed your natural limitations by changing your nature? ...I could have picked a lot here honestly.
Empire of Mercy: Seek out your potential and aspire to a greater world, no matter what you must break on the way.
