Ancestry Paragon
Source GM Core pg. 86
Many characters have some elements that connect them to their ancestry but identify more strongly with their class or unique personality. Sometimes, though, a character is the embodiment of their ancestry to the point that it's of equal importance to their class. For a game where an ancestral background is a major theme and such characters are the norm, your group might consider using the ancestry paragon variant.
Building an Ancestry Paragon Character
Source GM Core pg. 86
When creating an ancestry paragon character, instead of starting with one ancestry feat and gaining another at 5th, 9th, 13th, and 17th levels, the character starts with two ancestry feats and gains another at every odd level thereafter (3rd, 5th, 7th, 9th, and so on) for a total of 11 ancestry feats.
Playing with Ancestry Paragon Characters
Source GM Core pg. 86
Ancestry paragon characters have more versatility and power than other characters, though their extra abilities are usually limited to themes the ancestry already was suited for. It's unlikely to affect the game balance of combat encounters, but it might make exploration and social challenges easier for the heroes.
