At the top of each character sheet is a descriptor. This is a short introductory character summary. The descriptor is made up of the following elements, some of which are not always used..
Example: an aging rugged human bounty hunter who loves 50s music
The trait is the name of a special ability defined by a character's lowest or highest attribute.
The age entry is only used if the character is younger than adult or older than middle-aged. You may choose any synonyms for young and old (adolescent, youthful, aged, mature, etc.); age can give you a free exploit.
The hook is a broad background/skill/interest chosen by the player. It can be anything, but it's designed to round out the character with personality, interests, or hobbies. For example, a player might choose “...who enjoys hard liquor” or “... who has a taste for romance” or even “...who collects insects as a hobby”. The hook works as a broad skill. Any time you make an attribute check, you can use the descriptor to make the dice pool explode. The GM should be generous in allowing this; the hook should provide a frequent reminder of a character's background. What you can't do with the hook is gain a combat bonus to attack or damage.
Have each player read their full descriptor to the rest of the group before beginning play.
