Mixed Ancestries
Source Galactic Ancestries pg. 5
A culturally diverse galaxy of biotechnology and widespread magic is rife with opportunities to play a character with more than one ancestral heritage. You can always play a character with two or more ancestries in your genealogy who still uses the rules for a single ancestry, whether or not you take the Adopted Ancestry general feat. Characters who want abilities beyond the scope of that feat might consider applying a custom mixed heritage.
Custom Mixed Heritage: You can work with your GM to create a mixed heritage for any ancestry. A custom mixed-ancestry heritage is an uncommon heritage. Choose an ancestry to tie to the heritage. You gain any of the traits of that ancestry and a new trait for your combined ancestry. You also gain low-light vision if the ancestry tied to the heritage has low-light vision or darkvision. Furthermore, this heritage lets you select ancestry feats for the chosen ancestry in addition to those from your base ancestry. You can select any options from standardized ancestry feats shared by both ancestries.
For example, a skittergoblin who selects the Ancestral Skills feat becomes trained in their choice of Goblin Lore or Skittermander Lore, plus any two of the four skills listed for the goblin and skittermander ancestries: Diplomacy, Nature, Society, or Stealth. Work with your GM if you need a custom feat to represent the combined abilities of both ancestries.
