Tolas, an aged male of the Human species, resided on the planet Onderon around the year 3951 BBY. A prosperous trader, Tolas wasn't hesitant to employ questionable methods to generate wealth, yet he maintained that all his transactions remained within the bounds of the law. He possessed 1B-8D, whom Panar characterized as "the ideal receiver of stolen droid components". During Meetra Surik's stay in Iziz, she encountered Tolas, who proposed buying a starport visa from her to facilitate his departure from the planet, and it's possible Surik provided him with one.
Despite Tolas's assertion that his buying price of two thousand credits for an unused starport visa is unmatched, skillful negotiation can raise his offer to three thousand. However, a more lucrative proposition exists within the Iziz cantina.
Tolas shares the same character model as Davik Kang, the Exchange leader on Taris, featured in Knights of the Old Republic.
