Alderaan, a revered Core world, had long been a centre point in galactic politics, exploration, and culture. Alderaanian exploration vessels plied many of most important trade routes in the galaxy and as such became renowned traders and so occasionally colonists from Alderaan settled many scattered worlds. Alderaan was a beautiful blue green orb lacking moons, and was the home of a peaceful society governed by a viceroy. Unlike the crowded Core worlds like Coruscant, Alderaanian society struck a harmonious balance between urban centres and undisturbed wilderness. Alderaan was once home to a native sentient species that had long ago died out, an insectoid culture known as the Killiks, who left behind impressive hive-edifices (called the Castle Lands) on the Alderaanian grasslands after being forcibly evicted by ancient beings known only as the "celestials".
Much of Alderaan was covered by gently swaying grasslands and prairies. Alderaanian artists used the landscape itself to create living works of art, planting grasses of different hues and textures along carefully plotted paths. The savannahs supported a variety of ruminant life forms, such as grazers and nerfs, and ranching was a common occupation. The few metropolitan areas of the planet were designed in such a way to complement their surroundings. The city of Aldera's skyline consisted of gently curved, gleaming white buildings that formed a subtle bridge between the green grasses and white clouds. Here, students from across the galaxy studied at the famed University of Aldera, a learning institution that promoted inspiration and free-thinking. Other centres, such as Crevasse City, melded so perfectly with their surroundings as to be almost invisible from a distance unless you knew exactly what to look for. Since the time of the Clone Wars where the planet was turned into a devastated battleground Alderaanians decided to outlaw weapons and disbanded the small army it had. After this law was passed and years went by, the period of re-growth was spectacular, and Alderaan was once more renowned for its beauty, hailed as the "Bright Centre of the Universe."
