While their world lacked readily accessible resources like metals or wood, Lur had an abundance of lifeforms, both animal and plant. The Lurrians learned to domesticate certain creatures. They began by taming creatures for food, then transportation, then construction. Eventually, they learned that selective breeding could bring about desired traits. In time, the Lurrians discovered many natural herbs, roots, and compounds that, when administered to females ready to breed, could bring about dramatic changes in the genetic code of offspring.

Now, these beings have a very advanced culture based on their knowledge of genetic manipulation. While they lack technological tools, many of their newly developed lifeforms perform the functions of these tools. Swarms of asgnats burrow subterranean cities in the glaciers; herds of grebnars provide meat; noahounds guard the cities. The Lurrians have bred creatures whose sole purpose is to cultivate genetic code altering plants and herbs or to consume the wastes of their culture.

Over the millennia, the Lurrians have developed a peaceful society. These diminutive beings live long and enjoyable lives filled with recreation and merriment. They are social and live in cities of a few thousand each. Family ties are extremely strong and violence among citizens or individuals is rare. The Lurrians have a fierce love of their homeworld and few willingly leave it.

While genetic manipultaion is strictly controlled due to the atrocities of the Clone Wars, there are still those who seek genetics experts. The Empire has quarantined the world due to the Lurrians' abilities, but little effort is made to enforce the quarantine. Some resort to enslaving them to aquire their services.
