Dekamin is an exiled Carja thief living at a camp on the outskirts of Brightmarket. He was formerly a Shadow Carja refugee, but left Sunfall due to the poor living conditions. Because of his allegiance to the Mad King Jiran, he is no longer able to reside in Meridian and must fend for himself in the wilds of the Sundom.
To provide for himself he regularly stole fruit from Gulahni's storehouse in Brightmarket at night, however he stopped after Aloy's intervention. As penance, he runs errands for the sellers in Brightmarket as well as helping run Gulahni's stall under her supervision.
