Warto was a male Boltrunian who served the Cloud-Riders under the leadership of Serji-X Arrogantus. Originally a laborer on a Corellian freighter, his behavior and temper addled his crewmembers. In turn, he was abandoned by his crew on Aduba-3, where he was forced to eke out a new existence lifting crates and strong-boxes at the local starport, while also mugging several of the weaker locals. He came to spend most of his free time at Locru's Central Saloon, consuming large amounts of strong nikta.
