The Kwi did not have the ability to talk unlike the Kwa though they possessed a collective memory of their former glory and the importance of the protection of the ancient Star Temples. However, they could race at incredible speeds. In 31 BBY, many Kwi were slaughtered by the Nightsisters during their attempt to access the secrets of the Infinity Gate.
The remaining Kwi disappeared into the deserts and would form tribes including the Blue Desert People and the Blue Mountain People, as well as the Rhoa Kwi. The Kwi also migrated every dawn and every dusk.[1]
The Witches of Dathomir of the light side apparently respected the Kwi. The offer of a Kwi to let someone ride them was an opportunity the Witches considered to be a rare honor.[3]
