Onacra was a small farming community of about 100 people on Aduba-3. It was not too far from the planet's only starport, Tun Aduban. Most of the villages on the planet were set up by missionaries teaching the Sacred Way. Onacra was founded by a family that dissented from the missionaries' teachings. While adhering to most of the same beliefs, the citizens of the new village felt that many of the rituals of the religion were outdated. Eventually, the villagers worked out a deal with Arrogantus. Rather than fall victim to the Cloud-Rider's pillaging, they offered an annual tithe of 9,000 credits.
