Because Vorgo abandoned his jedi training in order to pursue happiness with his newfound love, he was never officially given the title of Jedi Knight.
He did train a lot of his powers, but was never given a real lightsaber.
Although unfortunate, this has helped Vorgo to avoid the consequences of Order 66. At that time, he was no longer seen as a Jedi Padawan and therefore, could escape the Inquisition that hunted down all force users.

Now that he has lost his family, he has decided to step up again and perhaps even train in the arts of the Jedi. Who knows, he might even get a chance to construct his own lightsaber on the path to the Light Side.

Vengeance:
Vorgo is in search throughout the vast galaxy for the one responsible for killing his wife and child.
They were cowardly murdered, whilst Vorgo was out hunting, by a bounty hunter. He assumes they were murdered by The Empire to prove their point as Vorgo refused their invitations once too many to work for them as a force-guided bounty hunter.
His search, with guidance from the force, led him to a dust sand planet, Tatooine, where he has a feeling that great adventure awaits in search for the destruction of The Empire.

Bravery and Anger (50 Light Side):
Vorgo's bravery is quite remarkable. Whether facing down a charging Rancor or racing into a burning building to save innocents, he is always willing to take risks to help others.

Hot blood, however, can easily lead to hot tempers. Vorgo is quick to anger and what he cannot deal with face-to-face can often frustrate him to the point of rage.

Vorgo is a strong muscled Zabrak of average height and weight. He's got a black tribal covering his face and body.
He has 8 small horns on his head.
