Save the Mantaris! (2002)

From the introduction:

This adventure idea, a companion to Secrets of Naboo, takes place in and around the Civic Spaceport in Theed. The Gungans are preparing to launch an effort to colonize one of Naboo's moons, using the Mantaris transport, a spacecraft developed in a joint effort between the Naboo and the Gungans. Queen Amidala, the ruler of the Naboo, and Boss Nass, the leader of the largest Gungan community both want this project to succeed, as they see it as the dawn of a new era of cooperation between their two peoples.

However, anti-Gungan (well, anti-alien in general) terrorists seek to sabotage the mission. Their first step is to kill a Gungan technician and kidnap one of the lead Naboo engineers. The evidence seems, on the surface, to point to disgruntled Gungans. A faction among the citizens of Theed that still considers the Gungans barbarians, rushes to judgment. The Gungan contingent in Theed blames these Naboo, claiming they are attempting to manufacture an excuse to wage war. The terrorists' plan is working like a dream.

Enter the heroes.
