Vrake

Although currently abundant, the strikingly patterned vrakes were on the verge of extinction for more than a hundred years. An enterprising Makeb scientist, Kaylah Taprish, took a liking to the creatures--she claimed their faces reminded her of her favorite uncle--and spent five years studying and crossbreeding them before releasing a dozen new colonies into the wild. Unfortunately, with their numbers increased, vrakes have now become fiercely territorial.

The head crest of a vrake resembles the face of another Makeb predator, the thunderhead hawk. Vrakes use the crest to startle prey--usually birds and small rodents--for the rest of their colony to pounce on. (Codex Text - Star Wars the Old Republic)

Voreclaw

A subterranean species of semi-sentient bipedal insects, the voreclaw survived the devastating ritual that wiped out all life on Nathema's surface... but not without cost. The dark side cataclysm obliterated the Voreclaw's hive mind, transforming their underground colonies into mindless individuals without purpose or will.

Driven by hunger, the voreclaw emerged onto Nathema's barren surface, where the sun's radiation seared their exposed flesh and charred their chitinous shells. With no other plants or animals to eat, the voreclaw resorted to cannibalism-- devouring each other until only the few strongest remained.

The species was saved from extinction when the Sith Emperor captured the few survivors to use as guardians in his underground vault. Frozen in carbonite, the voreclaw remained in suspended animation for generations--grim sentries waiting to be awakened should anyone be foolish enough to enter their new domain.

Vine Cat

The heavily armored, sharp-toothed vine cat can pounce up to eight meters and has been known to tear a sleen apart in less than ten seconds. Its armored frill and hide protect it against larger predators such as the jurgoran, and its claws make it an expert climber when it needs to get away. The vine cat was introduced to Dromund Kaas by the early Sith from the dark forest world of Ziost and is responsible for wiping out three of Dromund Kaas’s native herbivorous species to date.

K’lor’slug

Hulking, worm-like creatures with pincer legs and gaping maws of teeth, k’lor’slugs are among the most dangerous species on Korriban. Not only can they shear a man in half or swallow him whole, they can project their vile, venomous spit great distances. Hatched from eggs laid hundreds at a time by their queens and blessed with a short incubation period, these hideous monsters can infest and overrun an area in no time. 

A century ago, a notorious hunter named Riegenn Hetuu was contracted to bring a live k’lor’slug queen to an eccentric Hutt for a gala celebration. The beast was meant to be a highlight in the Hutt’s annual gladiatorial tournament, but when Riegenn arrived on Hutta and opened his cargo bay, some four hundred k’lor’slugs poured out, consuming the hunter as well as the Hutt. To this day, the sound made when a batch of k’lor’slugs hatch is called “a Hutt’s cry.” (Codex Text - Star Wars the Old Republic / SWTOR)

Rancor

Rancors are reptilian monstrosities known as some of the galaxy’s most dangerous predators. Although indigenous to the planet Dathomir, they have spread to many other worlds and thrived in many environments. Rancors are a favorite among the wealthiest underworld crime lords, who raise them from eggs to become (relatively) tame pets. Those whose rancors survive to adulthood are afforded a great deal of status, as well as a powerful weapon against their enemies.

A unique feature of the rancor is its tough hide–a mixture of fine scales, thick skin and bony plates. Blaster bolts and vibroblades have little effect upon the hide, and while these attributes fade from a hide removed from a rancor carcass, a few lucky hunters nonetheless wear ornamental outfits made from the material. (Codex Text - Star Wars the Old Republic / SWTOR)

Galactic History 08: Hyperspace Cannons

This datacron holds unheard of power and knowledge collected by an ancient race. You access its power and discover writings which are clearly only one small piece of a massive galactic history: 

Early spaceflights were conducted with sleeper ships, their crews preserved via suspended animation over the long journeys to other worlds. But these journeys were incredibly slow. Remembering the efficient hyperdrive technology of the Infinite Empire, the most brilliant scientists of the galaxy began to study what remained of those machines, despite the claims of Tiran, the Drall scientist who centuries before said that nothing could travel faster than the speed of light. 

Eventually, this led to the development of a hyperspace “cannon.” These cannons allowed a ship to be propelled into hyperspace, though a second cannon was required for a ship to return to its origin point. 

The Core Worlds quickly established a hyperspace cannon network. The children of Coruscant soon encountered the Duros civilization, whose people became some of the earliest–and most daring–hyperspace explorers. The true colonization of the galaxy had begun.

Galactic History 03: The Battalions of Zhell

This datacron holds unheard of power and knowledge collected by an ancient race. You access its power and discover writings which are clearly only one small piece of a massive galactic history: 

In the millennia before the founding of the Republic, humans had not yet developed spaceflight. One human population–perhaps the only one–was confined to Coruscant, divided into thirteen tribes. This nearly proved disastrous when a volcanic eruption caused a near-extinction event, wiping out a large percentage of human life. 

This made the humans easy prey for the Taung, a gray-skinned species that reveled in battle. Awed by the majesty of the eruption’s ash cloud, the Taung took the name “Warriors of the Shadow,” descended on the surviving humans and subjugated them. Gradually the fighting force of the thirteen human tribes–known as the Battalions of Zhell–mustered a resistance against the Taung. 

After years of struggle, the Battalions managed to repel the Taung and claim their freedom. Coruscant has been the seat of humanity ever since. (Codex Text - Star Wars the Old Republic / SWTOR)
