Every character has an Origin; this is what the PC was doing before being an adventurer, and in fact may be something they are still trying to do while wondering about and such. Rather then create an exhaustive list, I've tried to pick entries that emphasize a particular class and style of life (as well as the occasional weird one, like someone who is lost in time and/or space) as well as ones that come with a variety of benefits and drawbacks. Your character may begin play with a cart full of trade goods, partial ownership of a crossroads Inn or the ability to keep themselves and their friends from getting lost in the unknown wilderness. A PC's Origin, combined with their Class, helps define their skill set as well.
Choosing (Or randomly selecting) a Character Class is one of the final parts of the character creation process. You PC's class dictates a character's base Aptitudes as well as the sort of abilities a PC will bring to the table. There are four basic classes, which represent the broad archetypes you've likely come to expect when dealing with fantasy games. These are intended to be flexible and versatile, coming with built in options that help define a character further as they level up. Also included are four advanced classes, which are far more specific. While the options involved are fewer, they are intend to be more unique and geared to a particular style of play.
Species is an option for characters who choose a basic class. Human characters gain a bonus ability based on their class, while the various other races have bonuses (and penalties) unique to them. Some of the staples are here for those that have favorites, but most are unique to Break!! and designed with the sort of world that is implied by the game itself in mind.
One hope I have for future supplements (fingers crossed) is that the setting can be further defined by things like more Classes, Species and alternative Origin tables. While I enjoy waxing about legends and lore as much as the next Game Master, I feel players are often most in tune with the world expressed on (and via) their character sheet.
