Pirdia

The Pirdia is a type of creature that is native to the planet Parnassos. These creatures exist within the Star Wars universe, specifically in the novel "Phasma", which was written by Delilah S. Dawson as part of the Journey to Star Wars: The Last Jedi series of books. The novel provides a backstory to the character Captain Phasma, and the Pirdia plays a key role in her journey.

In terms of their physical features, Pirdia creatures are quite massive, possessing a distinctive silver tint to their bodies. They are similar in appearance to insects and have an exoskeleton covering their bodies, which is extremely hard and nearly impenetrable. Each Pirdia has six legs and they are known for their swiftness. Indeed, despite their size, Pirdia can move very quickly, rendering them a formidable predator in the wild.

As for their behaviors, Pirdia are known to have the unique ability to burrow through solid rock. This makes them an even greater threat, as they can easily surprise their prey from below. Furthermore, they can survive long periods without eating by going into a state of hibernation, in which they rest and conserve energy under the ground.

The Pirdia uses a unique form of predation where they hide in ambush, burrow up from beneath their prey, and attack. Given the harsh, post-apocalyptic environment of Parnassos, Phasma and her tribe were constantly under a threat of a Pirdia attack, which made survival there all the more challenging.

Despite their terrifying nature, the Pirdia are also a source of sustenance for the inhabitants of Parnassos. These creatures are huge and can kill easily but once defeated, they can provide greatly needed nourishment. This goes to show the tenacity and resourcefulness of the people living on Parnassos, effectively utilizing the dangerous wild creatures in their environment to their advantage.

the Pirdia of Parnassos are a perfect reflection of the harsh and challenging planetscape. Though they are creatures of fear and danger, they also provide survival opportunities, reflecting the quintessential ethos of Star Wars - struggle, persistence, and survival against all odds.
