Background bonuses will be assigned for character concepts. Some backgrounds will be required for certain starting classes.
1st Level Jedi:
There is not a well organized recruitment program for infants. Unless a parent seeks out the shaman council, or a shaman stubles uppon a young force user, there is no way for someone to start as a jedi. There is one VERY common exception. knights and masters are allowed to have families, and often do with other knights and masters. The resulting children are almost always force sensitive and are trained from an early age.
The only way to be a 1st level jedi, is to be the child of a jedi. Depending on back story, your character will be granted a gm chosen force talent or extra set of force powers.
A large part of the champaign will be recruiting mystics from accross the galaxy. You are one of these recruited mystics. Though not yet trained as a jedi, you have been recruited for your abilities with the force. You can be a mystic and chose any class besides Jedi. Depending on back story, your character will be granted a gm chosen force talent or extra set of force powers.
Super Soldier Trainee/SWAT Trainee:
Many military institutions have found that some extra funding and training can go a long way. A Super Sldier background often means that the character starts play with special equipment and possibly a bonus combat feat.
