Tolas was an elderly Human male living on Onderon in 3951 BBY. Tolas was a successful merchant who was not afraid to utilize shady practices to make money, though all his dealings were legal, as he said. He was the owner of 1B-8D, described by Panar as "the perfect fence for droid parts." When he was met by Meetra Surik during her visit to Iziz, Tolas offered to purchase a starport visa from her in order to get offworld, and Surik may have given him one.
