Goblin characters do not have to have either Horde or Blood feats, and may have either or both, if desired.
Goblins without a strong blood tie (a Blood feat) are considered lesser than ones who do, even those with the blood tie which is engulfed by the leading bloodline.
Goblins who are not a member of a horde (a Horde feat) have failed their test of adulthood, and are often fodder on raids.
Those without either are often exiled. Sometimes, these goblins find each other and form independent Camps, which may account for why reports of Goblin social behavior is so widely varied.
