Sass Sikili, a Verpine skilled in negotiation, delivered a speech at the inauguration of BastEx.
Sass held the responsibility of communicating with external parties for the Roche administration. He engaged in discussions with Boba Fett regarding a potential partnership with the Mandalorians, an alliance that ultimately gained approval from both factions. Sass cautioned the leaders of Murkhana that the Roche government would retaliate proportionally if they persisted in violating trade agreements concerning technology exports. Following Murkhana's continued exportation of technology, Sass reached out to Fett, conveying the Roche government's desire for the Mandalorians to handle the situation in Murkhana. The introduction of the Tra'kad by the Mandalorians later became a source of bewilderment for him.
