Selective cultures only allow visitors and immigrants from specific places. Such a culture does not allow others from places deemed dangerous, but may make an exception with heavy vetting.

Bonus: If you come from a selective culture, increase the dice sizes of one of your Mental skills to a d12, one of your Social skills to a d10, any other skill to a d10, any two skills you want to a d8, and any three other skills to a d6.
