You have a pool of seven dots to allocate to advantages (backgrounds). A list of backgrounds can be found here. Notes:

• I strongly encourage you take at least two dots in the Avatar background. Without it, it's almost impossible to store your own quintessence and I intend to have the characters avatars involved in the game.
• You do not have to spend any points on the Mentor background. I will be allocating everyone mentors as part of the game.
