Primordial Ones & Primal Ancestry Feat in PFS

[Chovesh]

I'm about to start my first PFS game Thursday and I'm thinking of a doing a build that is Unarmed Fighter at Level 1 and then becomes a goliath druid.

The Primal Ancestry feat requires being a member of the Primordal Ones (Pathfinder Campaign Setting: Andoran, Birthplace of Freedom).

QUESTION
How do I accomplish this within PFS since it shows that the Primal ancestry feat is legal for play?

Do I have to be a druid first, or can I simply start out as a non-druid member?

My question is unclear, it should be "Can one start out as a member of the Primordial Ones" or does something special have to happen for this to occur in PFS play?

It sounds like a role playing requirement: those are waived in pfs.

I can't find the Primal ancestry feat to check though. I don't have the book and its not in nethys yet.
