While he was traveling through the galaxy in one of his ship with a crew of smuggler, they coincidentally came across a galleon belonging to a group of slavers. Saadoon-Kauldi's crew boarded this galleon and they witnessed the poor conditions in which their hosts's slaves were being treated.
Saadoon-Kauldi, who had been a slave himself in the past, lost his temper and brutally killed all the slavers. He then released all the slaves.
To his surprise, the slaves swore loyalty and service to Saadoon-Kauldi. The Kadri'Ra understood that this increased his own influence and prestige. Believing himself to be a better person than his victims, Saadoon-Kauldi decided to give his new followers a good amount of respect.
Besides this, this skirmish prompted Saadoon-Kauldi to temporarily destinate his resources to the release of an ever bigger number of slaves.
