The free archetype

The campaign uses a custom version of the Free Archetype official rules variant.

During character generation you may create one or more significant NPCs as part of your life (wife, kids, mistress, uncle, blood brother, drinking buddy, homeless guy you're taking care of...)

Choose your free archetype at character generation. You may choose any one archetype from the profession category: Profession category at Nethys

At 2nd level and every even level thereafter you gain an extra class feat, to a maximum of the number of created NPCs. These feats can only be used to take archetype feats from your chosen archetype. Special: You are free to select another dedication feat before you have gained two other feats from your free archetype.

So if you create five NPCs you have given yourself the right to pick five feats from your chosen archetype for free.
