K'kayeh dragon

The k'kayeh dragon was a gigantic, serpentine beast that was created by the Sith Lord Darth Rivan to defend his fortress on the planet Almas. The dragon was 200 meters in length and was covered by thick skin as strong as armor that was the exact color of the sands of the Almas Wasteland that surrounded Rivan's fortress. The creature preferred a subterranean lifestyle and rarely strayed to the planetary surface, instead choosing to spend most of its time roaming the deep underground caverns and swimming along subterrestrial rivers.

After Rivan was driven from Almas during the New Sith Wars, in his absence the k'kayeh continued to reside on Almas for over a thousand years, coming to be regarded by the population of Almas as a creature of legend. Circa 17 BBY, the gatekeeper of an ancient holocron that Rivan had created summoned the dragon to attack the Imperial Inquisitor Valin Draco and a group of Alderaanian Resistance agents inside a cavern beneath a ruined Jedi academy. The agents withstood the creature's attack, and after Draco was sent tumbling off a ledge and into a deep chasm below, the k'kayeh ceased its assault and retreated.
