INFO: Cereans were a sophisticated and cultured humanoid mammalian species that hailed from the planet Cerea in the Mid Rim. They had tall tapering heads, which housed large binary brains, enabling them to focus on many things at the same time. Aside from this unique feature, Cereans were physically similar to Humans, although they possessed an extra heart, which supplied extra blood circulation to support their brains.
Cerean males aged more quickly than the females, who had similar lifespans to Humans. Thus, there were fewer males than females. Polygamous marriage was a necessity in order for the species to survive. Each male usually had one primary "bond-wife", and between four and ten "honor-wives".
Famous for their extraordinary thinking abilities, Cereans were often found among the ranks of the Jedi Knights, being exempt from the Jedi's vow of celibacy, due to their low birth rates. One such Jedi, Ki-Adi-Mundi, served the Jedi High Council during and prior to the outbreak of the Clone Wars.

HOMEWORLD:Cerea was a planet located in the Mid Rim region of the galaxy. The homeworld of the Cerean species, Cerea was notable for its inhabitants' harmonious relationship with nature. Technology and pollution were frowned upon by the conservative government, a major point in the planet's decision not to join the Galactic Republic. The Cerean population mainly lived in giant buildings that took up a minimum of space, allowing the remainder of the planet's area to be employed as farmland. Foreign immigrants and visitors were, with a few exceptions, only allowed in Cerea's Outsider Citadels, enormous buildings erected to let non-Cereans practice their technological ways. This ensured that the foreigners' technology did not contaminate Cerea's nature, but also led to a concentration of criminal elements within the Citadels.
Cerea was ruled by the Council of Elders, which in turn was led by a president. The planet was situated far away from any major hyperspace routes, and was for the most part ignored by the Republic until a few years prior to the Clone Wars. Cerea's seclusion caused a unique culture to develop, one that focused on other values than the mainstream galactic civilization. In 21 BBY, Cerea was the site of a battle between the Republic and Confederacy of Independent Systems, which had an adverse effect on the planet's relatively untouched nature. For further info please see the post below.
BIOLOGY AND APPEARANCE:Their enlarged skulls, extending up to twenty centimeters above their foreheads, housed complex binary brains, provided with sufficient blood by an extra heart in their heads. The binary structure of Cerean thinking helped them to ponder two sides of an issue at once. It also enables them to process information and solve problems rapidly. Because of their thoughtful nature, they tended to be calm, rational, and analytical, preferring peaceful philosophies and a lifestyle which worked in harmony with nature. Though the quick-thinking Cereans had equally quick reflexes, they were commonly not as well coordinated as Humans. Because of the weight of their enlarged skulls, Cereans often had back problems.
CULTURE AND HISTORY:Cereans developed a low-tech society on their homeworld, and preferred to live in isolation from the wider galaxy. However, during the years leading up to the Invasion of Naboo, a generational dispute erupted on Cerea when the younger generation took up a rebellious stance against their low-tech society. Many Cerean youths wished to own such technology as was commonplace in the Galactic Republic, like starships and speeder bikes. This unrest was ultimately quelled by Jedi Knight Ki-Adi-Mundi, who traced the instigator of the movement, Ephant Mon, to Tatooine.
Many Cereans used specially-forged Kasha crystals as a meditational tool. By focusing one's thoughts while in contact with such crystals, distractions were eliminated, creating an exceptional meditation environment. Cerean Jedi sometimes incorporated these crystals into their lightsabers, providing great focus, even during intense physical combat.
IN THE GALAXY:Ki-Adi-Mundi served as Jedi Watchman for his home system, though he relinquished this post during the Clone Wars to fellow Cerean Tarr Seirr. When Seirr was also called away, the Cereans were left undefended, and their planet was attacked by the Confederacy of Independent Systems. The death toll of the Battle of Cerea reached over one million, and included the family of Ki-Adi-Mundi. This led to the Cereans becoming even more removed from galactic affairs with the rise of the Galactic Empire.
By the time of the Yuuzhan Vong War, the Cereans had developed a unique Force tradition, known as the Ner Yan. This group used the Force to link their minds, although in a haphazard manner. Ka-Tu-Un was an adept of this tradition and was mistaken for a Jedi by the Yuuzhan Vong.
