Ok, Cain was the first vampire. In his body God's curse is most potent. Each Vampire that he embraced would be of the 2nd Generation( Cain being the first generation). He embraced 3 Vampires (2nd generation). They Begat 13 known as the Antediluvians who are the founders of the clans(okay not exatly 13 but I am trying to simplifiy, they are 3rd Gen)
Each of the 3rd Gen was cursed in some way and they pass their curse down to all of their children, which is the basis for the clan weaknesses.
All of that happened a long time ago,(during biblical times, the 3rd Gen were around before the great flood iirc), the blood of the vampires who are around now is a lot thinner and less potent as the average starting vampire is of the 13th Generation. You may purchase a lower generation(and more power) at character creation by putting points into the Generation background trait. Each point you put in lowers your generation by 1.
You only get 5 points to put into your background and if you dont put anything into resources, thats exactly what you have, nothing at all, no money, no where to live, nothing.
Dots refers to your ratings, as in drive 2 is 2 dots of drive, its a coloquialism based on the fact that the character sheets are just blank dots to be filled in.
I wouldn't mind helping anyone make a character as I have finished Sabrina.
