Piasas constituted a sizable avian species native to the world of Koboh, these birds were easily identifiable due to their significant size and axe-shaped beaks. The piasa occupied the position of an apex predator on Koboh, inspiring dread in any animal that caught its attention as potential prey. These creatures were primarily nomadic, seldom settling down to roost. Nevertheless, one particular piasa had established a nest within the Boiling Bluff region, situated close to Rambler's Reach Valley. During the year 9 BBY, [Cal Kestis](/article/cal_kestis], a Jedi Knight, alongside his droid partner BD-1, came across a piasa at the Forest Array located on Koboh, and they liberated it from a dense accumulation of Koboh dust that had ensnared the massive animal.
