"They embraced space and for that they were rewarded with the gift of a flawless sense of direction."
- – Paladin, Wing Commander
Driftborn were introduced Starfinder as a newly emerged subspecies of Gnome; like Bleachlings they appear to not succumb to the affliction that haunts Feychildren. They began appearing some time after the creation of the Drift plane by the god Triune. Compared to the rest of their kin, Driftborn are more exotic with lithe physiques adapted for space travel and shifting, iridescent patterns on their skin. They also possess a strong instinctive sense of spatial positioning and orientation. These adaptations appear to have arisen from prolonged exposure to drift travel.
In essence, they're the first evolutionary step towards gnomish navigators.
From a stats perspective, Driftborn use the same statlines as other Starfinder gnomes but they get +2 Dexterity instead of +2 Charisma (Feychildren) or +2 Intelligence (Bleachlings).
