Kodaian

The Kodaians were a race of beings which were native to the planet Kodai. Skittish and reclusive by nature, the Kodaians were nearly wiped out by an immense tidal wave, about a century before the Battle of Naboo. Many of the survivors fled off-planet, rather than waiting for the next tidal wave. Those that remained on Kodai were suspicious of strangers, fearing that the appearance of other beings would signal the onset of another tidal wave. They also feared the seas, and built great walls around their cities in order to keep the water out.
