Odan-Urr

This datacron holds unheard of power and knowledge collected by an unknown individual. You access its power and discover information unknown to many:

Odan-Urr, Jedi Master and founder of the Great Jedi Library of Ossus, was one of the order's most famous and long-lived members. Although he participated in some of the most decisive battles of his time, Odan-Urr preferred the life of an academic, overseeing the library's Chamber of Antiquities for centuries until he was slain by Exar Kun shortly before the cataclysm inflicted by the Cron Supernova.

Of his many accomplishments, perhaps the most influential of Odan-Urr's works was his revised version of the Jedi Code, which he created in response to the struggles of his pupils to fully understand and embrace what it meant to be a Jedi. Odan-Urr's revised wording of the code became the definitive version, taught and recited by Jedi ever since. (Codex Text - Star Wars the Old Republic / SWTOR)

Galactic History 16: The Alsakan Conflicts

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:

During the boom period of early Republic expansion, dissent arose from the unlikeliest of quarters: the planet Alsakan. Colonized by the first explorers from Coruscant long before the development of the hyperdrive, Alsakan had been a member of the Core Worlds for centuries.

But as the planet grew more powerful and influential, its Senators believed that Alsakan, not Coruscant, should be the capital of the Republic. A series of skirmishes called the "Alsakan Conflicts" broke out, slowing Republic growth as it tried to quell Alsakan's forces.

Despite the best efforts of Republic diplomats and generals, Alsakan remained belligerent, and seventeen such uprisings would occur over the next several thousand years. Later, the battle cruisers built during the Alsakan Conflicts would inspire the Republic's Invincible-class dreadnought. (Codex Text - Star Wars the Old Republic / SWTOR)

Evocii Tribes

Although most Evocii remember little of their culture now, it is certain that the Evocii once existed in hundreds of tribes scattered throughout Hutta’s (then known as Evocar) once-lush surface. Usually ruled by a married couple acting as paired chieftains, the Evocii tribes traded and competed with each other, building monuments as proof of their comfort and superior resources. 

The most honored members of the tribe were rarely the chieftains themselves; the Evocii placed higher value on healers, trackers, and those who could predict Evocar’s intemperate weather. The tribes were not entirely peaceful, though; the Evocii preferred cunning guerilla attacks and raids to assaulting their enemies directly. 

The Hutts ignored the structure of Evocii society when they obtained control of the planet. Tribes were split up and intermingled, eventually losing their identity altogether. Only fragments of Evocii tribal culture remain, mostly in the communities that resisted Hutt rule and vanished into Hutta’s swamps. (Codex Text - Star Wars the Old Republic / SWTOR)

Underwalker

“Underwalker” is the Makeb nickname for a species of subterranean insectoid carnivores. The shell of an underwalker is astonishingly resilient and shares the properties of some of Makeb’s ores. Biologists believe that the underwalkers may have mutated over millennia of drinking water contaminated by mineral deposits. Whatever they once were, underwalkers are a constant menace to Makeb’s mining engineers because underwalker territory is often around the richest seams of mineral wealth. More than one underwalker has been sighted with tools lodged in its carapace: the sign of tragic events occurring around a newly bored drill shaft. (Codex Text - Star Wars the Old Republic / SWTOR)

Tythonian War Droid

The ruins of Kaleth are overrun with various squads of ancient–and hostile–war droids. A deadly remnant of Tython’s mysterious past, the original purpose of the droids has been lost in the mists of time. Some speculate they were once guardians, programmed to protect the powerful secrets of Tython’s original Jedi inhabitants. Others believe the droids were used for combat training by the order shortly after the creation of the first proto-lightsaber. A more sinister theory suggests the droids were somehow involved in the destruction of Kaleth itself. Whatever the explanation, one fact is not in dispute: The droids will attack any living creature that dares to enter the territory they still fiercely patrol. (Codex Text - Star Wars the Old Republic / SWTOR)

Trinthan Prowler

Cat-like and deadly, the Trinthan prowler originated in the Trinith system before being sold across the galaxy for use as trained hunters and trackers. After a string of incidents where bystanders were badly mauled, the Republic made Trinthan prowler breeding illegal and a large number of the beasts were released into the wild. They can now be found on a great many planets, where their predatory skills have allowed them to thrive feeding on smaller, slower and weaker creatures. (Codex Text - Star Wars the Old Republic / SWTOR)

Tonitran

Keen eyesight, an insatiable appetite and a bone-chilling call make the tonitran one of the galaxy’s most feared predators. These remorseless lizards use their muscular hind legs to gain purchase with their powerful claws and propel themselves at great speed, often resulting in a successful kill without their prey ever having known they were in danger. The substantial tail of a tonitran not only assists in its balance, but it also provides excellent defense against any creature foolish enough to attempt a furtive attack from behind. (Codex Text - Star Wars the Old Republic / SWTOR)

Terentatek

The legendary terentatek is a vicious, tusked monster that feeds on the blood of Force sensitives. Terentateks are known to cluster wherever there is a strong dark side presence and to remain dormant for many years before emerging to hunt. 

How terentateks came to be is a subject of much debate. Ancient chronicles report terentatek-like creatures on Korriban, twisted by the dark side rituals performed by early Dark Jedi. Other sources attribute their creation directly to the Sith Lord Exar Kun, who performed many Force experiments on creatures on Yavin Four. Terentateks are undoubtedly one of the most vicious of all creatures steeped in the dark side, and they are doubly dangerous because of their unnatural resistance to Force powers. 

Jedi throughout the ages have tried to wipe terentateks from the galaxy, but the creatures have proven incredibly resilient. The most recent concerted effort was three centuries ago; many terentateks were destroyed, but the hunt took the lives of many Jedi Masters, as well. (Codex Text - Star Wars the Old Republic / SWTOR)

Subteroth

Subteroths linger in the nightmares of every Makeb explorer. Armored, muscular and utterly deadly, these hulking beasts typically live in deep underground caverns, where their eyes have atrophied over time. Instead, subteroths hunt using scent and the crest on the back of their head, a hypersensitive organ that picks up the electromagnetic fields of a prey’s heartbeat and transmits it directly to the subteroth’s nervous system.

Makeb’s recent groundquakes have driven the subteroths out of their normal hunting grounds and toward the surface. Being surrounded by an abundance of prey and curious interlopers has driven the already-lethal subteroths into a feeding frenzy. (Codex Text - Star Wars the Old Republic / SWTOR)

Stoneray

Of all the creatures indigenous to Yavin 4, the stoneray fits most suitably within its dark side-permeated swamps and jungles. Their ashen skin and low-necked posture lend an air of the sinister. And at night, bathed in the crimson glow of the gas giant Yavin, stonerays appear to be covered in blood–a terrifying sight, especially when one is observed using its taloned tail to effortlessly disembowel its prey.
