On the back of the Sophont Creation Card there's a section to record the caste name next to each value from 2 to 12. This implies that the roll to determine C6 also automatically determines caste (and maybe gender). Conversely, if one selects the sophont's caste and gender, then the C6 value is determined automatically without a die roll.
