Tralls was employed as the teacher of Current Events at the Junior Academy of Applied Sciences, situated in Lothal's Capital City. In his role as an educator, Mister Tralls utilized his Current Events courses as a platform to disseminate propaganda that supported the developmental initiatives of the Galactic Empire. For example, he presented Zare Leonis and his classmates with a skewed narrative regarding the Trade Federation's crop engineering endeavors on the planet Chrona. According to the Empire's official historical account, the Trade Federation intentionally instigated a famine by limiting crop production, thereby forcing the local populace to rely on their monopolized medical services. Tralls asserted that the Galactic Empire heroically intervened by nationalizing agriculture and reintroducing the enhanced crops.
Zare's parents' personal experiences on Chrona sharply contrasted with Mister Trall's account. Zare clarified that while the Trade Federation had indeed created its own genetically engineered crops, they had not released them to the public due to their unreadiness for widespread use. Zare conceded that the corporation had delayed the distribution of these crops, but emphasized that the delay only lasted for one year following a court ruling in the Galactic Republic's favor. Zare further mentioned that his parents were the developers of these crops and were present on Chrona during the crisis.
Mister Tralls took exception to Zare's opposition and instructed him to remain after class for a private discussion. Tralls rebuked Leonis for challenging the official government's version of events and accused him of harboring sympathies for the Trade Federation, an allegation Leonis refuted. Tralls reminded his student that the purpose of the Current Events class was to demonstrate the necessity of a powerful central authority—namely, the Galactic Empire—within the galaxy. Tralls further elaborated that the absence of a strong central government impeded progress and the well-being of galactic citizens. After securing Zare's commitment to future compliance, Tralls dismissed him.
