Each character is described by three Attributes that describe her basic strengths and weaknesses, as well as how she approaches life. Those Attributes are Verve, Affinity, and Guile, and they are rated either D6, D8, or D10.
A D10 in an Attribute indicates an high rating in that Attribute, while a D6 indicates a low score and D8 is average. During the character creation process, you get to choose one Attribute at D10, one at D8, and one at D6.
Affinity is your character's ability to grasp how the world operates, both people and objects. Affinity includes a degree of intuition and natural ability at skills; characters with high Affinity are often builders, healers, or preservers. Aim, Treat, Intuition, Society, and Cultivate are examples of Affinity skill specialties.
