What's Next?
A core character is just the skeleton of a character; there's more you can do to make your character fun and interesting. Now you have two possibilities: make a "real-world" character, or make a character for a specific genre such as fantasy or science fiction (sci-fi). Ask your GM what sort of game they're running and what sort of character you need to make.
Real-World Character: If you are playing in a campaign set in the "real world" and are playing a normal person, you also get a descriptor (which gives you another skill and more points to add to your Pools) and get to pick another skill based on your profession. More information about turning your core character into a real-world character is explained in the Real World chapter.
Genre Character: For most other games (such as fantasy or science fiction), you'll need to pick a type, focus, and descriptor; together with what you chose as a core character, this means you're an extraordinary person (and probably live in an extraordinary setting). You can choose your type, focus, and descriptor in any order, but many people like to start with a type because it includes a lot of important stuff related to the game genre. The types you can choose from depend on what genre the GM is running—fantasy, science fiction, superhero, and so on. As you continue building your character, it's okay to go back and make changes to things you decided earlier. For example, if you put most of your core character's Pool points into Might but the abilities from your type or focus mostly use Intellect, it's okay to move some points around so your final character's Intellect Pool is bigger than how you set up your core character.
Whether you're making a real-world character or a genre character, the information in the other chapters will remind you about what a core character gets and how the new parts of your character add to that.
