Sea Leviathan

The Sea Leviathan was a semi-sentient form of Sithspawn, alchemically engineered by the Givin Vul Isen, a scientist in Darth Krayt's One Sith Order. Inspired by the original creation of the exiled Dark Jedi who became the first Sith Lords of millennia past, the Sea Leviathan was born in the depths of the aquatic Outer Rim planet of Dac solely to kill the native Mon Calamari species in accordance with Emperor Krayt's ordered extermination of the entire race. With assistance from the Quarren Sith Lord Darth Azard, Isen summoned the Sea Leviathan from the depths of Dac's Soheras Trench and unleashed it upon the seemingly helpless Mon Calamari, who had been detained in the Imperial Extermination Camp 28.

In 137 ABY, the same year of its creation, the Sea Leviathan met its demise when it was attacked by the Mon Calamari Rangers, led by Imperial Master Treis Sinde. Despite the Leviathan's successful massacre of many Mon Calamari, Sinde was able to coax a school of devilsquid with the Force into an attack on the Leviathan. Unable to defend itself against the assault, the monstrosity was subdued and dragged into the abyss of Devil's Crevasse to be ravaged by the devilsquid.

Biology and appearance
The Sea Leviathan was an aquatic beast specially bred by the Givin Vul Isen, a scientist of Darth Krayt's One Sith Order, for life in the deep seas of the Outer Rim planet of Dac. It was a creature of considerable length and mass, being of far greater proportions than either the Aquatic Terrain Armored Transport[1] or the Acklay-class mobile fortress,[2] two vehicles used by the military of the Empire. The Sea Leviathan had pectoral fins that were on either side near its chin, as well as a taloned caudal fin for propelling itself through the waters of Dac.[1]

The Sea Leviathan had long tendrils surrounding a gaping maw filled with rows of long teeth.[3] Like its terrestrial cousin,[4] it had two sets of yellow eyes—one atop the other—and four nostrils in a similar arrangement. The Sea Leviathan had a green hide,[1] in contrast to the purplish skin of its land-based kin.[4] Cranial horns were situated on either side of its face and head, which gave way to the rows of blister pods that began at the creature's neck and continued down the length of its entire body. The pods served as siphons of life-energy, as well as being the Sea Leviathan's primary means of attack. Because of special engineering on the part of the beast's creator, the Sea Leviathan only drew upon the energies of the Mon Calamari species; its blister pods were not used to effect any other.[1] Though bred on the planet Dac, the Sea Leviathan was not part of the native fauna. When encountered by the resident Mon Calamari, they recognized it as foreign and regarded the beast with terror before fleeing.

Behavior and intelligence
Despite its considerable girth, the Sea Leviathan had incredible speed; it was often able to out-swim its prey and was even able to keep pace with underwater attack craft.[2] Like its land-based relatives,[4] the blister pods with which a Sea Leviathan was equipped were used to siphon life energy from its victims. The beast actively hunted its prey, and when in close proximity, the blister pods resonated with a sickly green aura as they began to drain the life of the intended target.[1] Due to Vul Isen's special engineering, however, the Sea Leviathan only activated its blister pods when hunting Mon Calamari and did not use them when combating other sentient or non-sentient species. Should the beast be attacked by other creatures or beings, it relied only on its size, speed, and teeth as a means of defense.[2]

Sea Leviathans were not a natural occurrence, but were instead a variation of the terrestrial Leviathan that was created through alchemical practices millennia before by the exiled Dark Jedi of the Hundred-Year Darkness. In accordance with Darth Krayt's ordered extermination of the Mon Calamari species, Sith scientist Vul Isen engineered a semi-sentient beast that was not only indulgent upon the life energy of its victims but was also able to assimilate their sentience as well. Each absorbed life allowed the Sea Leviathan to think more like a Mon Calamari; it then instinctively located them in their dwellings and commenced massacring them in kind. The power of the Force was required to bring the beast to life. Through their mastery of the dark side, Vul Isen and his colleague, the Quarren Sith Lord Darth Azard, imprinted parts of their own consciousness onto the Sea Leviathan's mind to awaken it from its vegetative slumber. Once alive, Lord Azard was concerned that as the beast harnessed the sentience of more Mon Calamari, it would turn on the Sith; however, Isen assured him that because their mental imprints were part of the Sea Leviathan's mind, it would ignore them and only hunt its intended prey.

History
In the year 137 ABY, Dread Lord Darth Krayt ordered that ten percent of the entire Mon Calamari species was to be exterminated for their support and allegiance to the Galactic Federation of Free Alliances, the former dominant galactic government.[5]  He commissioned one of his many Sith Lords, the Quarren Darth Azard, as the overseer of his genocidal will. Azard traveled to the Mon Calamari homeworld of Dac, where scientist Vul Isen was also sent and ordered to expedite the success of the Quarren Sith's mission. Lord Azard was content with rounding up the Mon Calamari in detention camps and simply letting them all die of starvation or disease.[1] Isen, however, had more creative methods of committing genocide and was eager to implement one of his schemes to satisfy Lord Krayt. After consulting the Chagrian Sith sorcerer Darth Wyyrlok, Isen created an aquatic version of the land-based Leviathan to unleash upon the helpless Mon Calamari. Once his oceanic Sithspawn was ready, both he and Darth Azard used the Force to bring the Sea Leviathan out of hibernation from the Soheras Trench and then set it upon a group of Mon Calamari that had been detained in the Imperial Extermination Camp 28. Impressed by the efficiency with which the Leviathan consumed its prey, the two Sith unleashed their handiwork into the waters of Dac as bait for the Mon Calamari Rangers, freedom fighters who had assumed the responsibility of protecting their kinsfolk from the attacking Imperial Sith.[1]
