Kwa

The Kwa were a species of sentient blue lizards from the planet Dathomir. They were one of the first species in the galaxy to travel offworld and used a mysterious technology called an Infinity Gate to travel across the galaxy. They had a tendency, upon encountering more primitive species, to "enlighten" them by teaching them how to use the force and gave them ships and stuff. Then they tried it with the Rakata, who subsequently pwned them into near extinction. The remaining Kwa fled back to Dathomir, when a few thousand years later, the Witches of Dathomir would wipe them out. The Kwa also loved the colour blue, painting their temples technology in the colour, heck they even went so far as to attempting to change the atmosphere of every planet that they went to, to the colour blue.
