Zephyrus was a slavemaster who, in 1100 BBY, outfitted the slave caravel Sickly Tremor with durasteel cages to bring slaves he claimed could heft a cargo skiff in one hand to Ovise III. However, the shipment never arrived, and Zephyrus's fate remained a mystery, although it was theorized his ship crashed on Endor, and that the slaves he boasted of were ancestors of the moon's Phlog population.
